There are groups of 3 and groups of 4 in the example shown.**How many groups of three are there? How could we add them up?*Your child may have a variety of different ways to work this out. Ask them to see how many ways they can use. They may:

- count in ones: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
- count in threes: 3, 6, 9, 12
