Thursday: The berry picnic
Chris the Coyote sits on a log and tips his feathered hat.
"Once, the trail friends planned a berry picnic," he says.
"Bennie filled 5 baskets with 8 berries in each basket."
"Hazel set out the cups in 3 rows of 6."
"Then Rosie the Rabbit hopped up with her bandana flying."
"Is there enough for everyone?" she asked.
Story: Counting the picnic
Bennie has 5 baskets. Each basket has 8 berries.
That is 5 groups of 8, so 5 × 8 = 40 berries.
Hazel has 3 rows of 6 cups.
That is an array, so 3 × 6 = 18 cups.
