Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 6
- Let's take away across ten. Here's 14 minus 6.
- Break the 6 into two parts: 4 and 2. Why 4? Because 14 minus 4 lands right on 10!
- 14 minus 4 is 10. Then 10 minus 2 is 8.
- Your turn: 13 minus 5. Tap to jump back to 10 first, then take away the rest.
- 13 minus 3 is 10, and 10 minus 2 is 8. So 13 minus 5 is 8!
- Take away just enough to get to 10. Then take away what's left. Ten is your stepping stone!
