It's Kangaroo's birthday, but no one will play with him: not the emu, the platypuses, the koalas, or even the dingos. They all have too many things to do. What exactly are they doing? They're using multiplication to figure out just how many things they have to do to plan a big surprise for Kangaroo! Best Children's Science Books 1997 (Science Books and Films)
