Dots in groups
You learn to count amounts in groups, without counting every dot separately.
How to work it out
- Don’t count every dot: see how many are in one group.
- Count the groups in jumps.
- Then add the dots that are on their own.
How many dots? 3 groups of 4 and 1 more.
- See how many are in one group: 4.
- Count the groups in jumps of 4: 4, 8, 12.
- Add the dot on its own.
- So 13.
More examples
2 groups of 5.
5, 10: that makes 10.
4 groups of 2 and 2 more.
2, 4, 6, 8 and 2 more: 10.
