Friday: Freddy's big review

Freddy the Frog has decorated the whole pond with lanterns for the last game of the trail.

"Ribbit! Today every friend brings a puzzle from our twelve weeks," he says.

Ferris the Fox, Rosie the Rabbit, Lizzy the Lizard and Hazel the Hedgehog line up along the bank.

Bennie the Bear sets down his basket of stones. "Take each puzzle one step at a time."

"Look how far we have come," says Ferris, waving his map. "From big numbers to angles!"

Freddy straightens his bow tie. "Let the big review begin!"
