KIRKUS REVIEW
A captivating counting book that relies on a riddle to keep children interested while they learn some math. Farmer Roy is determined to scare away the crows that are eating his sweet corn sprouts. With friends and family he embarks on a complicated game of musical chairs, trying to fool the crows into thinking that no one is watching the cornfield. Somehow the crows outsmart Roy, figuring out that he is hiding in the toolshed, ready to scare them away. Young readers have to figure out how the crows know Farmer Roy waiting for them, a puzzle that requires them to do some arithmetic. Based on an experiment that determined crows could count, this tale will have readers as baffled as Roy is, and just as satisfied when he sends off a few warning shots into the sky, scaring those calculating crows off for good.
