My son asked if we could read "I'm a Frog!" by Mo Willems. It is a cute easy-reader story. He helped me read it in fact.
We talked about the life cycle of a frog with this printable to help use as a visual.
We used many activities from this Frog in the Pond Preschool Pack.
2 Teaching Mommies has a Frog Unit printable Pack.
My husband helped us out by folding this simple origami frog. It does a little hopping.these cute frogs. We also went to Starfall and found the song there and did the letter F activities.
