Which is the best strategy to solve this problem?

Mary-Ann is making gift baskets for her friends. She has 32 candles and 64 lotion bottles. She splits the candles and lotion bottles equally among 8 baskets.

How many items were in each basket?

A.

Draw a diagram.

Draw 8 circles to represent baskets. Think 32 : 8 = 4, so draw 4 candles in each circle. Think 64 : 8 = 8, so draw 8 dots in each circle. Count up the objects in a circle to find the number of items in each basket.

B.

Guess and test.

C.

Write a number sentence.

(32 + 64) * 8 =
