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.

It's Albert's first trip to the amousement park. He says he's not afraid to go on rides-he just doesn't like ones that go up and down. Or left and right. Or around and around! But what happens when Albert ends up in line for the wrong ride? Every Mouse Math title includes back matter activities that support and extend reading comprehension and math skills, plus free online activities. (Math concept: Direction Words)
