Honestly, fitting in is hard sometimes. Leroy and Vivian are familiar with the struggle, because although they are mostly just typical second-graders... they're also slightly terrifying monsters. Kids will learn not to judge fellow kids OR subtraction problems by their looks with this handy resource. At first glance, these subtraction problems may be a little intimidating.

But kids will soon see that it's not what's on the outside that counts, but what's on the inside. Yes, even in subtraction problems.
