Is everything here really free?
Yes. You need a Share My Lesson account to download, and that is free too. We are run by the American Federation of Teachers, not a marketplace, so nothing sits behind a paywall.
How do I find lessons for my grade?
Use the tabs above the resource list: PreK, K-2, 3-5, middle school, high school. Every resource card shows its grade range, so you can check before you download.
Can I search by standard?
Yes. Search a code like 5.NBT.A.2 and you will land on a page listing every resource aligned to it.
