What this lesson shows
Fixes a mistake
883 is odd, whatever its 8s say.
The worked example
The lesson works this one step by step: 883. Then your kid tries one like it on paper.
The steps
- Not the big digits
- Only the ones decide
- Pair them up
Helping at home
Cover every digit but the ones. Only the ones digit decides: pair its dots, and see if one is left over. The other digits never change it.
If your kid gets stuck
Cover every digit but the ones.
