What it is
Equal groups are groups that all have the same number, like 3 bags with 4 apples in each. An array is things lined up in straight rows and columns, where every row has the same number. Both are found by adding the same number again and again: 4 + 4 + 4 = 12. This is where multiplication begins in third grade.
What comes next
Multiplication in third grade, which is a shorter way to write equal groups.
How to teach it
- Make equal groups with real things, like snacks on plates or crayons in cups.
- Look for arrays around the house, like egg cartons, muffin pans and windows.
- Say "3 rows of 4" before writing the addition.
- Skip count to check. 4, 8, 12.
Common mistakes
- Counting rows and columns the wrong way around. Rows go across.
- Writing one addend too many or too few. There should be one number for each row or group.
- Drawing arrays with uneven rows.
