Multiplication arrays How can we easily solve 6x3? 6x3 is the same as saying: “6 groups of 3”. If we make the groups, we can easily find the answer.

Multiplication arrays Let’s make those groups. Remember, 6 groups of 3; write them on your whiteboards.

Multiplication arrays If we rotate the array, is the answer still the same? Yes! 6 groups of 3 is the same as having 3 groups of 6. 6x3=18 3x6=18

Division arrays We can use the array to solve division. 18÷6= 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

Division arrays 18 divided into 6 groups makes 6 groups of 3. 18÷6=3 Think back to the multiplication sum. Can you see the link? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

Division with remainders Solve 65÷10 Make groups of 10 to start with.

We have 6 groups of 10. How much is that in total? 6x10=60 60 65 +5 There are 5 left over

65÷10= 6r5
