Today, I will build whole numbers from 51 to 100 using base ten
Vocabulary
Steps
Base ten blocks:
1. Identify the number in the tens place. Build it and record how many. 2. Identify the number in the ones place. Build it and record how many.
8 tens = 80
6 ones = 6
3. Count by tens and then count on by ones. Record the whole number
8 tens + 6 ones = 86
