Counting Past the Hundreds
Count forward and back by ones across hundreds: 198, 199, 200, 201.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 14
- Counting by ones is easy, until we get to a new hundred! Let's count: 196, 197, 198, 199.
- After 199 comes 200! The ones and tens are full, so they make a new hundred.
- Your turn! Start at 297 and tap to count on 4.
- 297, 298, 299, 300, 301. You crossed into the 300s!
- It happens with tens too: 408, 409, 410. After 9 ones comes a new ten.
- Counting back works the same way, backward. 302, 301, 300, and then 299!
Georgia's K-12 Mathematics Standards:
- 2.NR.1.2 — Count forward and backward by ones from any number within 1000. Count forward by fives from multiples of 5 within 1000. Count forward and backward by 10s and 100s from any number within 1000. Count forward by 25s from 0.
