Kindergarten Math · World 3: Ten Frame Pond · Level 17
Building Teen Numbers
Put a teen number together and break it apart on ten frames and a rekenrek.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 17
- You can build a teen number. To make 16, fill one ten frame: that's ten. Then put 6 more on the next one.
- You can break a teen number apart too. 18 is ten ones and 8 more ones. On the rekenrek: 10 on top and 8 on the bottom.
- Your turn! Build 15 on the ten frames.
- Your turn! Build 19. That's ten and 9 more!
- Try it with a grown-up! Make a pile of ten beans or pennies, then add some more. Say it: ten and 5 more is 15!
Georgia's K-12 Mathematics Standards:
- K.NR.3.1 — Describe numbers from 11 to 19 by composing (putting together) and decomposing (breaking apart) the numbers into ten ones and some more ones.
