In this podcast, Kelsey Rdzanek introduces listeners to the book Counting on Frank, written and illustrated by Rod Clement.
I selected Counting on Frank because it was very creative and included amazing facts that I thought kids would be interested in. For example, how many blue whales would fit into a house and how long a line a pen could draw until it ran out of ink. This book can be used for teaching about measurement and ratios, as well as topics like addition or subtraction.
