Expanded Form to 100 with Base 10 Blocks 1-97
Transition from ten frames to using Base 10 blocks to unitize and model numbers in units of ten and one. What's 83? 80 and 3. It's also 8 tens and 3 ones. To know there are 8 tens, add 5 tens and 3 tens. To encourage Base 10 thinking, use both formal names and nicknames. 83 is both "eighty-three" and "8 ten 3."
