Thursday: The challenge trail
Chris the Coyote tips his feathered hat.
"Let me tell you about the Challenge Trail," he says.
"Bruce hid 40 shells along the path, in piles of 5."
"Lucy found every pile, one by one."
"At the end, Bruce set out 6 baskets of 20 berries."
"Everyone shared them under the tall oak tree."
"Lucy said it was the best trail of the summer."
Story: Counting the shells
40 shells were in piles of 5.
40 ÷ 5 = ? is the same as 5 × ? = 40.
5 × 8 = 40, so there were 8 piles.
The berries: 6 × 20 = 6 × 2 tens = 12 tens = 120.
