What this lesson shows
Fixes a mistake
3 + 7 = 10, so 7 + 3 = 10 too. One pair of partners gives two facts.
The worked example
The lesson works this one step by step: 10 as 3 and 7. Then your kid tries one like it on paper.
The steps
- Fill some squares
- Count the empty ones
- Turn it around
- Partners both ways
Helping at home
Read each box aloud. After your kid finds the partner, say the pair both ways: "3 and 7, 7 and 3, both make 10."
If your kid gets stuck
Count the empty squares. Then say the pair both ways.
