Count by 25s
0, 25, 50, 75, 100, 125… (sets up quarters later).
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 16
- Let's count by 25s! 25, 50, 75, 100. Four 25s make 100, just like four quarters make a dollar.
- Keep going: 125, 150, 175, 200. It's the same pattern again, with a 1 in front!
- Your turn! Tap to count by 25s from 200 to 300.
- Did you notice? The endings repeat: 25, 50, 75, and then a new hundred. Over and over!
- That pattern goes all the way to 1,000: 900, 925, 950, 975, 1,000!
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.
