How to use it at home and in class
At home
Find factors in pairs, starting from 1, and stop when the pairs start repeating. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.
In class
Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.
Mistakes to watch for
- Mixing up the two words.
- Missing a factor pair by not checking each number in order.
What to practice before and after factors and multiples
- After: prime numbers, once this one is mostly right.
- Learn it first: the factors and multiples lesson and the factors and multiples chart.
