Children love talking about their age, it’s their special number. The How Old Are You? books are specific to 3, 4, and 5 year olds. Each page shows a different way to make that number with your fingers. For example, you can make 5 on two hands with 1 finger plus 4 fingers, 2 fingers plus 3 fingers, or 5 fingers plus no fingers. This fun game helps children visualize numbers and understand that larger numbers can be broken into groups of smaller numbers.
