A 100-page novel for 2nd graders about Claudia, a girl who is weak in mathematics but who studies hard to pass a class test with flying colors, only to get accused of cheating by the substitute math teacher because another student copies from Claudia's math exam.

If the first question looks too hard, find one that you CAN do, and then you can always go back. I looked down the page. There! Problem Six! I was sure I knew how to do that one. By the time I finished it, all the stuff I had studied had come back to me. […] I didn't work fast — I took my time and made sure I did not make any “foolish” mistakes.”

The parents make the mistake of not trusting Claudia. Some of her Babysitters Club friend believe her while others do not. The young readers can learn from the ways the disbelievers come to acknowledge their error and put their faith in her.

Interestingly, the very first paragraph of the book is:
