Friday: Freddy's sharing game

Freddy the Frog hops onto a lily pad covered in fraction cards.

"Ribbit! Welcome to the sharing game," he says, straightening his bow tie.

"Some cards ask you to share, so you divide."

"Some ask for groups of a fraction, and some ask for a fraction of a fraction."

Donnie steps carefully to the edge of the pond.

"I will go slowly and check each answer," he says.

Freddy grins. "Slow and careful wins every lily pad. Let the game begin!"

Try it
Hop like Freddy 4 times, and have a grown-up measure each hop.
Suppose each hop is 3/4 of a meter.
Multiply to find how far 4 hops go. Then measure to check.
