Isobel Adds It Up

The perfect book for math-loving kids is now in paperback! Isobel just wants to do her math homework in peace, but some noisy neighbors distract from schoolwork by making her wonder who could be making all that noise? Isobel is a problem solver . . . addition, subtraction, multiplication, division! But trying to figure out who is causing all the noise next door is one problem she can't quite work out. Is it a marching band? A basketball team in the middle of a practice? Could it be a family of elephants? Isobel doesn't know what to do about all the noise, but the solution just might come from the most unlikely place!
