Learning intention: I am learning to see the relationship between addition and subtraction and how fact families can be extended.

I know I’m successful when I can make connections beyond basic fact families.

Counting

There are 46 sultanas in a box.

Draw 2 different ways to arrange them to make it easy to count.

Here is a different example below:

Sultana

If I know that

6 + 4 = 10

This helps me know other facts too.

For example:

4 + 6 = 10

10 – 6 = 4

10 – 4 =6

40 + 60 = 100

100 – 60 = 40

100 – 40 = 60

16 + 4 = 20

14 + 6 = 20

26 + 4 = 30

20 – 6 = 14

50 – 6 = 44

Etc.

Can you see that the above equations have a connection?

Write down as many facts as you can for the following:
