    Love this site!!!

  2. Jenna Strawn says:

    Interested to look at your “Units at a Glance” but the link is broken. I’m loving what I’m seeing here so far. When are you anticipating getting the year 3 materials up? Thanks!

    • Thanks Jenna, just checked the link and it seems to be working. I went ahead and e-mailed you the Units at a Glance pdf just to make sure you can get it. I received the proofs for the first of the Year 3 Units today in the mail, so they should begin coming out within the next 2 weeks. Thanks!

  3. Amy Smith says:

    I just purchased the mom’s planner, and was excited to get to print it out tonight to get it ready, but in my email where it says ”
    Click the link below to download your order”, when I click, all I am directed to is a reciept for my order. Please help!!

  4. Irma says:

    I have subscribed twice today and I have not received my e-mail.

    • Hi Irma,
      What were you subscribing to? Were you signing up for our newsletter in order to receive the Free Unit 1-1 coupon code? Just checked our newsletter subscription service and it seems to be working, but we didn’t receive a request from you. Let us know if that’s what you were trying to do so we can troubleshoot the problem for you. Sorry for the confusion! Just shoot us an e-mail to contact@layers-of-learning and we’ll get you squared away as soon as possible. Thanks!
      Karen & Michelle

  6. Robyn says:

    Hi – I really want to use year four for the next school year. Do you think it will be finished by August?

    Thank you,

  7. Maria says:

    I would love to try out your free unit, not sure how to go about registering for it thou?
    Thank you 🙂

  8. Kori says:

    I am very excited about this program. Planning to get the first year right away. My only sad point is that Year 4 seems like it will be too centered on American history for those of us not in the USA. I understand why it was written this way but wish there was a way to make Year 4 more about current world history so it applied to all using it around the world. Just a little wish of mine… Great looking curriculum.

    • Hi Kori, Yes, we are aware that the Year Four in particular is very US centered and that we have many interested people from Canada, the UK, Australia and other places. We have toyed with the idea of writing a version that is more international or perhaps from the perspective of various English speaking countries. We might do that in the future.

  9. Kori says:

    I just wanted to comment on your customer service and how outstanding it is! Thank you for your immediate help (was not expecting an answer in the middle of the night – when are you sleeping?). We loved the first unit that we tried on trial basis and just bought the first year. Can’t wait to get started! Thank you!

  10. Martha Stanley says:

    I wanted to know how big the download for year one is? Worried about enough space on my device to get them all at once. Also would a good set of encyclopedias be enough extra resources for history and science? Really excited to try the curriculum.

    • Unit 1-1 is 17.9 MB. All of the units are about the same size. One unit will fit on an iPad or higher end tablet, a laptop or a desk top, but probably not on a phone. We recommend only downloading to a laptop or desk top if you are purchasing the entire year.

      A history or science encyclopedia are great basic resources to keep on hand because not every topic is covered in books and sometimes you just don’t make it to the library. But every unit has recommended book lists to search out at the library (or purchase if you like) and these really help to round out the information in a non-textbooky sort of way. You could get by with just the encyclopedias, especially in the pre-high school years, but we personally always heavily use our local libraries.

  11. Katie says:

    I’m a little confused. I thought I read that you plan for a 40 week school year, but all of these units are 20 weeks. Are you suppose to go through 2 units a year?

  12. Kelly Jeter says:

    When will unit four be completed? Will you include presidents in unit 4?

    • Do you mean Unit 4-4? We are ordering the proofs even now. It will probably be another three weeks before it’s out though. It includes revolutions around the world, the geography of the mountain west (United States), energy, and the second half of Romantic arts, mostly poetry and music.

  13. Renee says:

    I’m very interested in starting the curriculum with my will-be first grader in the fall of this year (2017). It looks like Unit 4-4 will be completed and released this year for sure, do you have a release schedule for the rest of Unit 4 (5-20)? Also, what do you recommend users doing for year 4 if they have completed years 1-3 and all of 4 is not released yet?

    • We know you’re anxiously awaiting. Units 4-4 and 4-5 will be released within two weeks-ish (by the end of February 2017 for sure). We don’t have a definite schedule for the release of the rest of Year Four. The more you harass us, the quicker we move, other than that, no promises. 😉

      If you are ready to move on to Year Four and we’re slower than you, then use the Units at a Glance and the encyclopedias we recommend in the Curriculum Guide to stay on track. We do have lots of activities and experiments in our lessons pages that fit with the Year Four curriculum.

  14. Cindy says:

    Is there a place to view the recommended book list for year 4? I’m considering this for my 8th grader next year, and I would like to see the books used before I purchase. Thank you.

    • Each unit has more than a dozen books in the “library list”, but none of the books are required. They are outside reading to broaden your understanding of the topics in each particular unit. Though we’ve reviewed and searched out the books in the library lists, you can actually choose any books that you like or that your library has. We don’t use the books to build the program on and almost none of the activities depend on a particular book (we do have explorations on things like “The Canterbury Tales” and “The Constitution”). We can’t provide a complete list partly because Year Four isn’t finished yet and partly because we don’t have a complete list for each year written up. The lists are only in each individual unit. If you’ve still got questions, please reply back!
