The 2nd graders are learning about Jackie Robinson at school and I thought this would be a great way to rein-force what they have already learned about him in a more comical way. Of course, they LOVE it! Like Meltzer's other books in the series, he has placed fun in history where children puts laughters in the equations of learning history. What a wonderful as always, and bravo for Meltzer. I will continue to purchase more of this series as I have already have a library of them and can't wait until the new ones comes out.
