Teacher Notes (not visible to students)
This activity gives students practice with tens and ones. It supports the standard: 1.NBT.2. Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: *10 can be thought of as a bundle of ten ones — called a “ten.” *The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones. *The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones). It gives a visual with base ten blocks and the standard form of the number are color matched to the blocks.
