What this lesson shows
Fixes a mistake
3 × 4 = 12 + 5 = 17 is false: 12 is not 17. Both sides must be the same.
The worked example
The lesson works this one step by step: 3 × 4 + 5. Then your kid tries one like it on paper.
The steps
- Not a run-on
- One step a line
- Every line true
Helping at home
An equal sign says both sides are the same number, so a run-on line like 3 × 4 = 12 + 5 = 17 is false. Write one step on each line, and check that each line is true.
If your kid gets stuck
One step on each line.
