Today we are going to be investigating pairs of numbers that make 9. This will be similar to our learning from yesterday.
Can you find 9 small objects (pasta perhaps) in your house and draw a bar model like this:

We are going to put all 9 things in the top "whole" section. Then we are going to split them up so that some are in each of the two "parts." We know that there are still 9 things altogether; I haven't added any more or take any away. The next job will be to count how many in each "part" and writing this as a number sentence.
For example:
| XXX | XXXXXX |
3+6=9
Independent Task: Can you use your bar model to find all the pairs of numbers that add together to make 9?
Extra challenge: Can you work systematically, starting with 1 item in one part and then moving one more across each time?
