These colorful, food-safe, dishwasher-safe, liquid measuring cups provide a hands-on way for children to learn measurement concepts such as volume, capacity, and fractions while cooking or engaging in imaginative play. Plus, the nesting design means they can double as a stacking toy. Rainbow fraction color coding makes it easy to find the right cup. Large, easy-to-read printing won't scratch off. Soft, easy-grip tops with pouring spouts and spill guards at the bottom prevent messes and keep the cups stable.  Includes 4 measuring cups ( 1cup, 1/2 cup, 1/3 cup, 1/4 cup) with metric measurements on the back side. Activity guide also included.
