Friday: Freddy's decimal game

Freddy the Frog sets out lily pads in a long line across the pond.

"Ribbit! Each pad has a decimal on it," he says.

"To hop to the next pad, you read it, compare it or round it."

Chris the Coyote reads the first pad out loud. "Three and fifty-two thousandths!"

Bennie the Bear nods. "Remember to line up the places."

"Last week we learned ten times and one tenth," says Freddy. "That helps too."

Everyone gets ready to hop.
