Monkey Math makes learning simple addition more fun than a barrel of monkeys. Just hang an equal number of colorful bananas from each of the monkey's hands. If you've done your addition correctly, the monkey will look straight ahead and his arms will be level. If the numbers are not equal, his eyes will be crossed and his arms will be up and down. That means it's time to try again. Includes monkey scale, fifteen banana number tokens, and detailed instruction booklet showing how to make learning simple addition a whole bunch of fun. Warning - Choking Hazard - Small Parts. Recommended for ages 4-6 years.
