Homeschooling in the Summer

I like homeschooling.  But not in the summer.

summer whining

It’s not that I’m even tired of homeschooling exactly.

I just want my time back.  For a little while.

The other day I read someone’s blog. (I have no idea now where I read it from, I just remember the shell shock afterward). They mentioned that they’re dreading the summer because their kids will be home and they will no longer have seven hours of alone time to do their home business work.

I nearly cried.

summer alone

Seven hours.  Alone.  For nine months.  Does she even get what that means?  Now, I know I chose homeschooling and I don’t have to do it, but that does NOT preclude the possibility of me simultaneously whining about it, because it can really suck sometimes.

Do you have any idea how productive I could be if I actually had hours on end in the house alone.

summer working

I might weed the garden.

I might actually run every day.

I might have a consistent routine.

Summer is actually a break.  Because, even though the kids are still here, I’m not sitting with them for four hours a day while they groan and moan about becoming useful humans.

I can tell them to go outside or they will do chores.

But the other half of my brain says, “You know what September will be like if you totally stop schooling over the summer.”

summer september

That’s right, they can barely remember their own names let alone the times tables.

Last summer we took off.  I didn’t have them retrained to do their work until approximately February.

I’m still nailing down what our school or lack thereof will look like this summer.  I keep trying to figure out how I can have them do math, reading and writing, without me being involved in any way.  It’s a tough nut to crack.

So what about you, do you take summer off and what does September look like afterward?

Journaling Your Scrapbooks and Portfolios

I’m a big believer in keeping records.  I keep scrapbooks of our family happenings, photo journals of our family vacations, and of course, school portfolios of my kids’ work.  We love to look back and remember our best bits, cool trips, and the progress we’ve made in our learning.  For several years my books involved mostly pictures, but I’m always amazed (and a little saddened) by how little I remember once a few years have gone by.  Now I make sure to include journaling in our pages to tell the stories that go along with the pictures.  Here are some fun ways to bring your pictures to life using words:

  • Use the ABC’s.  We went to Zion’s National Park and then made a ABC photo book of our trip.  Each page was a new letter. ABC Journaling
  • Take a picture of the words and projects.  My kids often want to keep all of their school projects, but I’ve taught them that if we want to keep something, it’s best kept in a picture.  We take lots of pictures of the things we learn about, and then we keep the memory without keeping the item.  I didn’t want to keep this giant water cycle poster, but my kids worked hard on it, so we took a picture that makes the words, and their work, stay with us.The Water Cycle (1)
  • Forget about long drawn out stories.  Sometimes a few words can say it all.  We had an amazing trip to Mexico, and interspersed these pages with just a few favorite memories.Short Journaling
  • Use favorite poems or quotes from books.  My mom took my sisters and I to Prince Edward Island, so naturally she made us this photo book of pictures and quotes from Anne of Green Gables:Quote Journaling
  • Use guest journaling – have others share their thoughts and favorite memories.  My kids told me what to type as they recounted the story of sending Daddy on a treasure hunt around town for his birthday on this page:Guest Journaling
  • Include a TOP TEN list.  I often ask my family what their top ten favorite things are about an event or a holiday.  I record their answers.  I love including things in “our own words.”
  • Record a funny conversation.  Every Cinco de Mayo we celebrate by making a Mexican feast and then having a tortilla toss.  We go into the yard and throw flour tortillas – the tortilla that goes furthest wins of course.  Well, several years ago on the SIXTH of May my daughter said longingly: “{Sigh}  The best days are Mexican days.”  She was fondly remembering the lovely time we had chucking tortillas across the yard the day before.  I about died laughing in the moment, but I wouldn’t remember it at all if I hadn’t written down in a little block quote on the scrapbook page.
  • Turn it into a storybook.  My mom created a spin-off Cinderella tale by dressing up all her grandkids.  One of their favorite things to do at our family reunions is play dress-up together, so this highlights them perfectly.Storybook Journaling

It doesn’t matter how you do it exactly, but record all those tasty memories so you’ll have a record of all the GOOD that your family is.  There is plenty of bad and hardship in the world, but your scrapbook can be a log of the good and wonderful parts that are your family.  Write them down!  Hold on to all those awesome memories you’re creating!

Navajo Tacos Recipe

Navajo Tacos are one of my kids favorite meals . . . mine too.  It’s a scone topped with chili, lettuce, cheese, sour cream, onions, olives, salsa and any other taco-like toppings you love.

power lines and navajo tacos 015

I always make the scones from scratch, so the recipe will include the bread dough and all, but you can use pre-made bread dough or crescent roll dough if you like.  I also make the chili from scratch so I’ll include chili directions, but again, canned is cool.

Navajo Tacos

Prep Time: 1 hour

Cook Time: 9 hours

Total Time: 9 hours

Yield: Serves 8

Serving Size: 2 Tacos

Navajo Tacos

Navajo tacos use fried bread rather tortillas for a filling Mexican style meal.

Ingredients

    Chili
  • 3 c. red kidney beans
  • 1 c. white beans
  • 1 16oz can tomato sauce
  • 2 T. chili powder
  • 1 t. salt
  • 1/2 T. onion powder
  • 1/2 pound cooked ground beef
  • water
  • Scones
  • 4 c. warm water
  • 2 T. yeast
  • 1/2 c. sugar
  • 8 c. flour
  • 2 c. frying oil or shortening
  • Toppings
  • shredded cheddar cheese
  • shredded Monterrey jack cheese
  • sour cream
  • salsa
  • sliced olives
  • diced onions
  • green onions

Instructions

    Chili
  1. Put the beans in a slow cooker, cover with water, plus 2 inches above the beans. Turn on high and cook for 6-8 hours.
  2. Add the tomato sauce, meat, and spices and cook for another hour or until heated through.
  3. Scones
  4. Add the yeast and sugar to a large bowl with very warm (but not boiling) water. Let sit for about ten minutes.
  5. Add flour, one cup at a time, until you can stir no more in.
  6. Dump the dough out on a floured counter and knead in more flour until the dough is no longer sticky.
  7. Let sit for 30 minutes then knead again briefly.
  8. Divide the dough into sixteen equal pieces. Roll each piece into a flat circle.
  9. Fry in hot oil in a skillet, one at a time until golden, flip and cook for another 30-60 seconds.
  10. Top with your favorite taco toppings.

So again, just top a fried bread scone with Chili and taco toppings.  We put all the individual ingredients on the table and let the kids add what they like.  That’s sure to make them happy.

They’re called Navajo Tacos because the Navajo people make fried bread similar to the scones in this recipe.

They’re yummy and if you opt for pre-made chili and pre-made bread dough you could get ‘er done in 30 minutes.

Magic Muck

Magic muck is a gooey concoction that kids will love to make. It’s super simple.  All you need is 3/4 cup of cornstarch and 1/3 cup water.  Combine them in a bowl or a ziploc bag and let the two ingredients sit for a few minutes without stirring. Then pick it up and mix it with your hands until it is well incorporated. If you want, you can food coloring and/or glitter to make the concoction colorful and sparkly.

Prep Time: 5 minutes

Magic Muck

Magic muck, oobleck, whatever you call it, it's messy fun. Plus it's a non-newtonian solid.

Ingredients

  • 3/4 c. corn starch
  • 1/3 c. water
  • food coloring (optional)

Instructions

  1. Mix corn starch and water, add a few drops of food coloring. Let it sit for about five minutes, then come back and mix it again.

Notes

This is not food. It's non-toxic though so if your two year old eats it, he'll live.

When you pick up a handful of magic muck and squeeze it will form into a hard ball. Now open your hand and watch the solid ball turn back into a liquid. You can experiment by adding different amounts of cornstarch and liquid to see what happens. When you’re done playing, seal it in a ziploc bag until you’re ready to play with it again.

Warning: This can get a little messy!!!

Here’s a video of a couple of grown-ups playing with slightly MORE magic muck!

Under The Stairs Sleeping Cubby For Kids

Isn’t this the cutest little under the stairs sleeping cubby for kids?

My dad and mom built this little bed cubby in the area under their stairs.  Besides all their great bedrooms, they’ve outfitted their house with little tucked away beds all over the place for their grand kids.  The curtain can close over it for privacy, and there’s plenty of room for a couple of kids to hang out a play video games in there too.  Love it.

Kids and Tools

I saw this post from “A Little Learning For Two” and absolutely loved it.

The family set up a work space in their garage next to Daddy’s workbench where their girls can do their own projects.  You’ve got to see the pictures for yourself.

They get their own hammers, measuring tape, screwdrivers, and screws.  Instead of hard to handle nails the girls practice pounding thumbtacks into balsa wood.  They’re not making a “project”, the girls just get to play, screwing bits of wood together any way they like.

I’m a big fan of letting kids do real stuff, not just play.  Kids are hungry to act like Mom and Dad, especially when they’re little, but even teens like real responsibilities, real challenges, and real success.

So this idea hit the spot for me!

Frozen Yogurt Dots

Fro-Yo Dots (2)I saw these little frozen yogurt dots on Pinterest and thought I’d give it a try.  It was a definite hit among all my kids.  We’re all yogurt fans.  We eat it for plain, make smoothies with it, and now we also make this yummy little treats.  They were really easy and fast to make.

You just scoop a few spoonfuls of your favorite flavor of yogurt into a plastic baggie.  Then line a cookie sheet with waxed paper and snip off one corner of the yogurt baggie to allow bits of yogurt to drop out.  Put drops of the yogurt on to the waxed paper.

Fro-Yo Dots (1)

 

It only took me a couple of minutes to fill 2 big cookie sheets.  Finally, you just slip the whole cookie sheet into the freezer.  Once the yogurt is good and frozen you pop the dots off the waxed paper and put them into a small resealable container and store them in the freezer.

My kids love having little snacks on hand, and these are pretty tasty.  The only drawback is that they thaw really fast once they’re out of the freezer, so they can only get a few out to eat at a time.  Really yummy though!

We’ve made quite a few flavors – strawberry, strawberry banana, peach, blueberry, lemon, and key lime pie.  We usually buy Yoplait because we love the flavor, but it will work with whatever your favorite yogurt is.   Hope you like these tasty frozen yogurt dots as much as we did!

What is Common Core and Why Should Homeschoolers Care?

What is Common Core?

Common Core is a movement to create a common set of standards, a common curriculum, across the entire United States educational system.  You can visit the Common Core website and read for yourself about the plan.

Common Core

The concept is that if students across the nation are all learning the same stuff, are all held to the same standard, then you won’t have some schools where kids are at a disadvantage to other kids across the nation.  A common curriculum also ensures common values and common culture across the United States.

Though on the surface Common Core appears to have laudable goals, when examined a little more closely some pure evil pops up.  For example, for all schools across the country to have the same expectations for their students, the standards have to be lowered to the least common denominator.  A quick look at the curriculum shows just how dumbed down it is.  For example, kids no longer read classic literature, literature that defines our culture and is part of the “great conversation” of ideas from the ancients to today.  Ideas, thinking, and facts are replaced by ideology like multiculturalism (the belief that all cultures and practices are equally valid, a variation on moral relativism), sexual promiscuity and deviance, environmentalism (the belief that “nature” is more important than people), and a denigrating of traditional American values and history.

Common Core reading material

The homeschool movement exists for the most part because the schools are already so bad at teaching kids.  If all of our schools are as bad as our worst schools, how is that going to fix the education system?  Proponents say that the worst schools will be raising their standards.  Okay, so let’s say we accept that the standards will align, not to the worst schools, but to average schools.  Average schools in America today are still really, really bad as far as academic achievement is concerned.  And why on earth would you pull down the best schools in the misguided idea that everyone should have “equal” results.

But that’s not the worst of it.  The scary part of common core is that all schools teach the same culture, the same values, across the entire nation.  Whose values?  Whose culture?  Exactly.  Not yours, we can pretty much guarantee that.

Your kids will be taught to accept all government approved behaviors and government approved belief systems and to reject those beliefs and attitudes not approved by government, which of course includes traditional families, Christianity, celebration of a belief in God, morality, virtue, and individual freedom.

Parents already complain they don’t have enough say in the curriculum taught in their local schools. Wait until the federal government gets their hands on it.  Common core, once adopted by a state is not optional for schools.  The teachers have to teach the lesson plans, they have to use the required books, they cannot add to or subtract from the curriculum they are given.  Teachers will no longer be anything but regurgitating administrators of the official government line.  Teachers who do not comply will be fired.

So why should Homeschoolers care?

Common Core is national, it applies to all children, no matter how or where they are taught.  There will be mandatory national testing, probably every year, that all students, including homeschoolers, have to take part in.  You will not be exempted.

Homeschoolers have become complacent because “homeschooling is legal in all 50 states”.  Yes, but there are many, many people who still are vehemently opposed to you teaching your children and passing on your values in your own home.  They want control of your children’s education.

I don’t care what or how you teach your kids.  I don’t care if you are classical, unschooler, or Montessori inclined.  I don’t care if you teach Christianity, New Age, Mormonism, Islam, Judaism, or Atheism in your home.  I don’t even care if you’re for all the “government approved” morality and teach environmentalism and homosexuality to your kids, as long as you don’t force it on me and mine.  But there are many people who do care.  Many of those people are in government.  The type of person who wants to control your life is drawn to government as a tool for force.

Freedom to Teach

Common Core is not as much a way to fix and improve our education system as it is a way to control the information your kids are exposed to.  It is a way to indoctrinate children to a particular world view.  Personally, I believe in indoctrination of children. Kids are always taught a certain way to look at the world; the difference is that I believe parents are the ones who should control that, not government.

What Can You Do About It?

The fight against Common Core has to happen state by state.  Most state legislatures, not seeing Common Core for what it really is, have already adopted it, to be implemented soon.  But it can be repealed and rejected.

Common Core

First you should learn more about Common Core.  Read what people on both sides of the issue are saying about it and decide for yourself what you think of it.  Then you should contact your state legislature, your local officials, and your state board of education about it.  Explain not only that you are against it (or for it) but why.  Give at least one clear reason for your opinion.  Our state officials need to not only know what we think, but they need to be educated on the issues and what they’re really about.

Mongol Empire Map: On the Eve of the Mongol Destruction

Every now and then someone comes along who completely changes the world.  Usually, not in a good way.  This could definitely be said for Genghis Khan and the Mongol Empire.  Most people know the Mongols had the largest contiguous empire in the world, second only to the British for biggest empire of all.  But do you know what the world looked like before Genghis took off on his warpath?  Here we present a printable Mongol Empire map you can color of what the world looked like On the Eve of the Mongol Destruction.

On the Eve of the Mongol Destruction in color 001

We colored the Christian nations in reds, yellows and oranges.  The Muslim nations are in greens.  The Buddhist nations are in browns.  Pagan or shamanistic people are shown in purples.  And the Hindu peoples are in shades of gray.  There is some overlap though and never does 100% of any people belong to the predominate religion.  Where there were large proportions of multiple religions, such as in Japan we chose the religion of the ruling class.

One interesting thing to notice are the kingdoms of Naimen and the Uyghurs in central Asia.  They are the only Christian nations far outside the Christian realms of Europe.  Makurra and Ethiopia are also Christian islands in Africa.  The people of Naimen had an ancient tradition that they were descended from the wise men who visited the Christ child after his birth.  They had always been true to their religion.  After Genghis began his conquest there were some Christian unit commanders from Naimen and Uyghurs who spared the lives of the Christians in the lands they conquered out of respect for their religion.

The Mongol Empire growing, swallowing most of Asia and part of Europe.

The Mongol invasions were appallingly destructive.  Most cities that resisted lost 100% of their population.  Most people were put the sword after surrendering, but young women and young men were taken as slaves, and skilled artisans were shipped back to Karakorum to build the capital and run the empire.  Millions died, hundreds of thousands were displaced.  Entire nations and races disappeared.  Libraries were burned.  The Mongols raided as far west as Spain and very nearly took the Holy Land which would have left Africa wide open.

So how did a bunch of stone age tribesmen, who had no cities of their own, who herded goats and raised horses, scratching a bare subsistence off the land, come to conquer great empires like Korea, China, Persia, and The Rus, not to mention completely dominate the best knights of Christendom?  The answer is one man: Genghis Khan.

Genghis Khan

Genghis reminds me of what Olivander says of Voldemort in Harry Potter and the Sorcerers Stone, “After all, He-Who-Must-Not-Be-Named did great things–terrible, yes, but great.”  Only Voldemort is a pansy next to Genghis.  Genghis is responsible for the death and sufferings of millions.

This printable map is part of Layers of Learning Unit 2.15, available later this summer.

Michelle Signature

Additional Layers:

  • People like Genghis Khan set civilization back hundreds of years.  Today if we think of central Asia at all, we think of sparsely populated backwaters.  But before Genghis the Silk Road route was littered with large, rich, advanced cities based on agriculture and trade.  The region has never recovered in terms of population or in terms of advanced technology of the age.  Other major set backs in civilization include the fall of the Western Roman Empire, the conquests of Islam, the Spanish conquest in the New World, the slave trade in Africa, and the Black Death in medieval Europe.  It can and almost certainly will happen again.
  • The Mongols were a pagan shamanistic tribal people.  After they created empires many of them adopted Islam, which spread the religion even further into Asia.  Before Islam and before the Mongols most of the areas we think of as Muslim today were actually Christian, including the middle east.
  • Look up the history of any one of these nations on the map.  They are all interesting, most are not in any of your history books, and becasue of the Mongols have largely been forgotten.  But they are in Wikipedia.
  • The Mongols tried to conquer India, but like Alexander before them, they failed.  In another couple of hundred years, descendants of the Mongols, now converted to Islam, would conquer northern India as the Mughals.

PVC Rocket

All rockets are powered by explosions.  All explosions are rapidly expanding gases.  Usually they’re expanding because they’re burning, but not always. In the PVC rocket launcher the propellant is burning hairspray.

PVC RocketThe Science Behind the PVC Rocket

In the rocket we built, the hair spray inside the tube is set on fire.  Hairspray is tiny particles suspended in the air, it is in aerosol form.  This means each little particle is mixed with lots of air.  And each little particle is also very inflammable, it will burn with the slightest provocation.  When the hairspray burns the chemicals in the hairspray, which usually includes some form of alcohol (I know, we put that stuff on our hair), mixes with oxygen and forms carbon dioxide gas.  The carbon dioxide gas formed is in much greater concentration than that of the surrounding air.  That means the pressure inside the launching tube is much greater than the pressure outside.  The easiest way for this pressure to escape in the PVC rocket is by popping the foam rocket off the launcher, so that’s what it does.  The force is enough to send the rocket 40, 50, or 60 feet into the air.

How to Build the PVC Rocket

First the base:

  1. You need an 18″ long piece of 3″ diameter PVC pipe, a 3″ end cap, and PVC primer and cement, plus a BBQ igniter and a couple of 1 1/4″ self taping screws.
  2. Glue the end cap on  to the PVC pipe.
  3. Use a power drill to put the self taping screws through the PVC pipe about an inch from the bottom of the pipe (the end with the cap).  When you’re finished you want the tips of the screws to be about 1/2 inch apart inside the PVC tube so you get a good arc between them.  Just before you finish tightening the screws down, insert the naked wire ends of the BBQ igniter under the screws so they have good contact with the screws.

foam rocket and pvc launcher

Now the rocket:

  1. Cut a piece of foam from a sleeping pad, like the kind you go camping with, so that it fits around the launcher tube and has just a bit of extra space.  When the body is finished it needs to be snug, but able to slide on and off the rocket launcher.
  2. Tape the seam with duct tape then strap duct tape around the body to make it strong.
  3. Cut a 2 liter pop bottle in half and slide the top half (the half with the cap) onto one end of the foam rocket body.  Secure it with more duct tape.  This makes the nose of the rocket.
  4. Next cut fins from more of the foam pad.  The exact size and shape isn’t important and they don’t have to exactly match each other.  Just eyeball a 45 deg cut ending in a square end.  Secure the fins to the rocket body with hot glue.  Make the fins angle around the rocket body in a gyre shape so when the rocket is launched it will spin.  This makes it fly straighter.

How To Launch the PVC Rocket

  1. Do it outside.
  2. Spray hairspray, the cheapo kinds work best, into the launch tube for about 2 seconds.
  3. Slide the rocket over the tube.
  4. Have everyone stand back a bit.
  5. Click the BBQ igniter.

The BBQ igniter makes a spark inside the hairspray filled tube and BOOM!  the rocket takes off.
