This comes with all the different categories for one price. Theres shapes, colors, numbers, letters, animals, bugs, food, transportation, mammals, birds, fish, reptiles and amphibians, spring, summer, fall, winter, musical instruments, art, sports, camping, money, fractions, roman numerals, symbols, yard, kitchen, bathroom, tools, trees & flowers. Best part is my son (born April 2010) loves this app and I would much rather he use my iPhone for this than watching cartoons or movies. Thanks toddler teasers.
