What they’re learning
Your child is learning that multiplication describes equal groups. An array is a tidy arrangement in rows and columns that makes those groups visible. The same array can also help them see related division facts.
Explain it to my child
Multiplication is a quick way to count equal groups. If we make 4 rows with 3 counters in each row, we have 4 groups of 3, so 4 × 3 = 12. We can also turn it around: 12 shared into 4 equal rows gives 3 in each row.
Try it together
Use coins, LEGO pieces, buttons, or cereal. Make 3 rows of 4. Count by rows, then by columns. Ask: “What multiplication facts can you see? What division facts can you see?” Rearrange the same 12 objects into a different array.
Practice
- Draw an array for 3 × 5. How many objects are there?
- There are 4 rows of 6 dots. Write a multiplication equation.
- 18 counters are shared into 3 equal rows. How many counters are in each row?
- Write two multiplication facts for an array with 2 rows and 7 columns.
- 24 cards are arranged in 4 equal rows. How many cards are in each row?
Check understanding
- Can your child explain what each number means in 4 × 6 = 24?
- Can they use one array to write a multiplication fact and a related division fact?
Parent answer guide
- 15
Three groups of five make 15. - 4 × 6 = 24
Rows × objects in each row gives the total. - 6
18 ÷ 3 = 6. - 2 × 7 = 14 and 7 × 2 = 14
Turning the array does not change the total. - 6
24 ÷ 4 = 6.
