Counting to 30
Say the numbers in order to 30, and what comes next.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 21
- All aboard the counting train! Let's count past 20: 18, 19, 20, 21, 22, 23.
- This is a number chart. Each row has ten numbers. Counting goes across a row, then on to the next row.
- Numbers in the twenties sound like twenty and a number you know: twenty-one, twenty-two, twenty-three, all the way to twenty-nine. After twenty-nine comes thirty!
- Your turn! Tap the number that comes after 24. It's the very next box.
- Try it with a grown-up! March like a train and count every step, all the way to 30. Choo choo!
Georgia's K-12 Mathematics Standards:
- K.NR.2.1 — Count forward to 100 by tens and ones and backward from 20 by ones.
