Arrays for multiplication
Use arrays to represent multiplication and division situations
What a learner can do afterwards
- Build an array of 3 rows of 4 objects to show 3 × 4
- Read an array and state the total
- Use an array to solve a simple division problem (e.g. 12 objects in rows of 4 → 3 rows)
The lesson
When objects sit in neat rows and columns, that is an array. Arrays help you multiply and divide fast.
Tap to fill the grid, one at a time: 3 rows of 4.
Try it together
Mia's egg box has 3 rows. Each row holds 4 eggs. She counts 3 × 4, so she has 12 eggs.
Tap to fill the grid, one at a time: 3 rows of 4.
Good to know
You can read an array backward too. 12 eggs in rows of 4 make 3 rows. That means 12 ÷ 4 = 3.
Rows and columns in an array show multiplication and division together.
