Math (4-7)

From the Publisher: Ten sly piranhas are swimming in a river, but one at a time they disappear, until there is only one left.  Now that this proud overeater is the only surviving piranha, he is confident that he can eat anybody.  But while he may be the cleverest fish in the river, he is no match for the giant crocodile lurking on the bank.  Children will love learning to count backward in this crafty tale about one very hungry piranha.

From the Publisher: Here is an adorable picture book for curious kids, which explores skip counting and estimation in a fun pumpkin-themed classroom experiment. “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.”
