The My First Green Toys Stacking Cups are colorful and fun, and teach basic counting and math concepts. Each cup is numbered on the bottom from 1 to 6 and is volumetrically accurate. Fill cups 1 and 4, for example, and it will equal the volume of cup 5, as will cups 2 and 3.
Six graduated cups, dozens of possibilities for bath and play time. The blue, green, and purple My First Green Toys Stacking Cups let children scoop and pour water, build towers by turning them upside down, or just sort sizes to nest. Made from food-safe, 100% recycled milk jugs in the USA. No BPA, PVC, or phthalates. Recommended for ages 6 months and up.
