This book helps students understand the standard K.NBT.A1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
Students use ten frames to model teen numbers are a group of ten and some ones.
The booklet was created so that the numbers are in random order. Print pages 1-6 with the odd pages on one side and the even pages on the other side. Don't print page 7 -- it's just and extra blank that got stuck in there.
Each set of three double sided pages makes 2 books. Print, fold, staple the books and then cut. Quick and easy :)
