About this skill
Substitution is the first step into algebra. Put the number in brackets so the sign and the order stay clear.
How to teach it
- Circle the part to do first and rewrite the expression after each step.
- Remember that multiplication/division and addition/subtraction pair up and go left to right.
- Check by estimating.
Mistakes to watch for
- Doing addition before multiplication because it comes first on the line.
- Applying multiplication before division even when division appears first.
