What this lesson shows
13.8 − 6 + 3 = 4 × 1.2 is false: 10.8 against 4.8. Work each side to one number.
The worked example
The lesson works this one step by step: 13.8 − 6 + 3 = 4 × 1.2. Then your kid tries one like it on paper.
The steps
- The equal sign means the same
- Work each side
- Compare
Helping at home
The equal sign says both sides are the same number. Work each side to one number in the order of operations, then compare: the same number is true, different numbers are false.
If your kid gets stuck
Work each side to one number.
