The document provides instructions for dividing multi-digit numbers by single-digit numbers using repeated subtraction. It demonstrates dividing numbers by highlighting the times table being used, circling the number of groups, and subtracting that number of groups from the full amount until reaching zero. Examples are shown dividing 72 by 4, 84 by 6, 96 by 6, 112 by 8, 108 by 6, and 125 by 5.

The easy way to divide!
72 ÷ 4 = 18 18 4 72 we know 10 x 4 40 32 we know 8 x 4 32 0 We highlight the times table we are using. We circle the number of groups.
84 ÷ 6 = 14 14 6 84 we know 10 x 6 60 24 we know 4 x 6 24 0 We highlight the times table we are using. We circle the number of groups.
Try this one on your whiteboard… 96 ÷ 6 = 16 16 6 96 we know 10 x 6 60 36 we know 6 x 6 36 0
Try this one on your whiteboard… 112 ÷ 8 = 14 14 8 112 we know 10 x 8 80 32 we know 4 x 8 32 0
Try this one on your whiteboard… 108 ÷ 6 =18 18 6 108 we know 10 x 6 60 48 we know 8 x 6 48 0
Try this one on your whiteboard… 125 ÷ 5 =25 25 5 125 we know 10 x 5 50 75 we know 10 x 5 50 25 we know 5 x 5 25 0
