Understanding color concepts can be learned through play. Locate 4 colored blocks: red, yellow, green, blue. Put the red block in your child's hand. Say, "Red." Put the yellow block in your child's hand. Say, "Yellow." Put the two blocks together in front of your child. "May I have red?" Put out your hand and say, "Thank You." "May I have yellow?" Do the same with the remaining 2 blocks. Put the blocks in a basket and put it on your child's toy shelf. This activity is fun to repeat.
