Chapter Overview
Equal groups must contain the same number of objects.
Counting in Groups introduces skip-counting and equal groups. Children arrange objects in twos, fives, or tens, then count the groups instead of counting every object one by one.
Making Equal Groups
- Pairing means making groups of 2.
- Five groups of 2 contain 10 objects altogether.
- Objects left after equal grouping are called leftovers.
Skip-Counting
- Count by 2s as 2, 4, 6, 8, 10.
- Count by 5s as 5, 10, 15, 20.
- Skip-counting is faster when every group has the same size.
