Multiplication and division using arrays (15x15)

Lesson

Arrays are a great way to not only work out multiplication and division problems, but they can also help us understand how multiplication (working out a total) and division (sharing) are closely 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)
