They're Up to Something in There

Inventors Oscar and Frank know THEIR rivals are up to something. And THEY'RE sure that whatever lies behind the fence, in THERE, is going to give them a run for THEIR money in tomorrow's pancake contest. Illustrated in a graphic-novel-like format, this delightful story pairs with back matter that clearly illustrates when to use the homophones "there," "their," and "they're."
