Quick revision
Remember these!
- Equal sets have the same number of items in each group.
- 15 pencils grouped into sets of 5 makes 3 equal sets.
- Equal grouping connects to multiplication and division.
- 3 sets of 5 is the same as 3 x 5 = 15.
- We check for exact grouping by dividing and checking leftovers.
- Equal grouping prepares us for multiplication and division.
- This skill helps organise items, like packing boxes.
- Grouping and counting go hand in hand.
