Mr. Tiffin and his students explore skip counting and estimation in a fun pumpkin-themed classroom experiment! This book makes a wonderful read-aloud companion to any math or science curriculum, and it's a fun way to reinforce counting skills at home."How many seeds are in a pumpkin?" Mr. Tiffin asks his class as they gather around the big, medium, and small pumpkins on his desk. Robert, the biggest kid, guesses that the largest one has a million seeds, Elinor, sounding like she knows what she's talking about, guesses the medium one has 500 seeds, and Anna, who likes even numbers better than odd ones, guesses that the little one has 22. Charlie, the smallest boy in the class, doesn't have a guess.Counting pumpkin seeds is messy business, but once the slimy job is done, to everyone's surprise, the smallest pumpkin has the most seeds! As Charlie happily exclaims, "Small things have a lot going on inside of them."And don't miss the newest addition to the Mr. Tiffin series, The Dinosaur Expert!
