Grade 2 · Number · Lesson 1
Meet Numbers to 200
The position of each digit tells how much it is worth.
The big idea
Take 187 apart by place value
In 187, the 1 means one hundred, the 8 means eight tens, and the 7 means seven ones.
- 1 hundred
- 100
- 8 tens
- 80
- 7 ones
- 7
100 + 80 + 7 = 187
A zero holds a place
What does 107 mean?
107 has 1 hundred, 0 tens, and 7 ones. The zero keeps the ones digit in the ones place.
