Multiplication and division using groups (15x15)

Lesson

Groups are a great way to see what we are doing when we

multiply - or work out how many items we have altogether, or
divide - when we share.

Using groups in this video, we also look at how multiplication and division are related.

Outcomes

5.NN3.01

Solve problems involving the addition, subtraction, and multiplication of whole numbers, using a variety of mental strategies (e.g., use the commutative property: 5 x 18 x 2 = 5 x 2 x 18, which gives 10 x 18 = 180)
