Multiplication as repeated addition
Understand multiplication as repeated addition and grouping equal sets
What a learner can do afterwards
- Explain that 3 groups of 2 is the same as 2 + 2 + 2
- Use objects to make equal groups and count the total
- Recognise an array as showing equal rows
The lesson
Multiplication is a fast way to add. You add the same group many times.
Tap each star and count out loud.
Try it together
Mia has 3 baskets. Each basket has 2 apples. She adds 2 + 2 + 2. That makes 6 apples total.
Tap each apple and count out loud.
Tap to fill the grid, one at a time: 3 rows of 2.
Good to know
When groups are equal, you can add them fast. Same-size groups added again and again is multiplication.
Multiplication means adding the same-size group again and again.
