Each read-aloud book in the Mouse Math series focuses on a single, basic math concept and features adorable mice, Albert and Wanda, who live in a People House. Entertaining fiction stories capture kids' imaginations as the mice learn about numbers, shapes, sizes and more. Albert has high hopes for the new squeakball season. He wants to score lots of goals! Then he gets his uniform number--a big, round zero. He runs and passes and makes lots of assists, but goals? Zero. His sister says zero is a secret super hero. Albert is sure it's cursed! Every Mouse Math title includes back matter activities that support and extend reading comprehension and math skills, plus free online activities. (Math concept:The number zero).
