Why integers are hard
You can’t hold negative three apples. Integers ask children to think of numbers as positions and directions, not just amounts. Rules like “a negative times a negative is positive” feel arbitrary if they’re only memorized.
Why algebra depends on them
Solving equations means moving terms, combining them and working with negatives constantly. A child who is unsure about integers makes sign errors that look like algebra problems but aren’t.
Integers are positions and directions, not just amounts.
What helps
Number lines, temperatures, elevations and bank balances make integers concrete. Explaining why the rules work, not just what they are, makes them stick. And plenty of short, spaced practice before algebra begins in earnest.
What you’ll take away
- 01Integers are positions and directions, not just amounts.
- 02Many algebra errors are really integer errors.
- 03Number lines and temperatures make them concrete.
