Everyone wants to have a nice piece of pie. Peg loved solving puzzles so when she had one very small piece of pie left over, the cat helped solve the problem. But they accidentally let all 100 chickens out of the coop. Now Peg has to solve the puzzle to collect them all. This book is nicely illustrated, but I’ve seen better books about problem solving. I do like how they use a simple math equation for the page number.
