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

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

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

To find the number of sweets remaining, I then subtract 600 from 882

To find the number of sweets remaining, I then subtract 600 from 882
Which is 282

- 600

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

- 600

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

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