The zoo animals were trying to have a fun party. But the sloths couldn't keep up with the penguins' dancing and the rhinos were accidentally popping the hippos' balloons. No one was having a good time until the kangaroo came up with an idea to change things up. With illustrations that are made easy for counting, this rhyming book takes you on an adventure with numbers that make up ten! Math activities are included at the end of the book.
