This document provides a step-by-step explanation of how to divide a 3 digit number by a 1 digit number using a chunking method. It uses the example of dividing 882 by 6. It works through imagining sharing sweets between children, giving chunks of 100, 40, and 7 sweets to each child and subtracting those amounts until there are no sweets left, showing the quotient is 147. The document encourages visiting a website for more math help and games and mentions a book on mastering multiplication tables.

2. When “chunking” I think of the question as referring to a certain
number of sweets (in this case 882) that needs to be shared between a
certain number of children (in this case 6). I then ask myself, how
many sweets can I give to each child?
6 882

3. In this example, I’ll start by imagining that I’m giving each child 100
sweets.
This is 6 x 100 = 600
6 882

4. In this example, I’ll start by imagining that I’m giving each child 100
sweets.
This is 6 x 100 = 600
This amount is placed under the 882
6 882
600
6 x 100

5. To find the number of sweets remaining, I then subtract 600 from 882
6 882
600
6 x 100

6. To find the number of sweets remaining, I then subtract 600 from 882
Which is 282
6 882
- 600
282
6 x 100

7. From the remaining 282 “sweets”, I then imagine that I am giving 40 to
each child.
This is 6 x 40 = 240
6 882
- 600
282
6 x 100

8. From the remaining 282 “sweets”, I then imagine that I am giving 40 to
each child.
This is 6 x 40 = 240
This amount is placed under the 282
6 882
- 600
282

9. To find the number of sweets remaining, I then subtract 240 from 282
6 882
- 600

6 x 100
6 x 40

10. To find the number of sweets remaining, I then subtract 240 from 282
Which is 42
6 882
- 600
282
- 240

6 x 100
6 x 40

11. From the remaining 42 “sweets”, I then imagine that I am giving 7 to
each child.
This is 6 x 7 = 42
6 882
- 600
282
- 240
42
6 x 100
6 x 40

12. From the remaining 42 “sweets”, I then imagine that I am giving 7 to
each child.
This is 6 x 7 = 42
This amount is placed under the 42

- 600

13. To find the number of sweets remaining, I then subtract 42 from 42

14. To find the number of sweets remaining, I then subtract 42 from 42
Which leaves zero

15. Altogether, each child has been given 100 + 40 + 7 sweets

16. Altogether, each child has been given 100 + 40 + 7 sweets
So, 882 ÷ 6 = 147
6 882
