What size?
When showing colors, shapes or sizes, say to your child, "This is a circle and it is red." Look at a colorful magazine picture and ask, "What else can we find that is red?" Reinforce the names of colors, shapes and the concept of size using everyday opportunities, personal items and items in nature. Examples: What color is that bird? Whose shoe is bigger: yours or mine? What shape is this ball?
