As you talk with your child, describe sights, sounds, tastes, and textures using number words. For example, you can say: I see two bright lights, I hear three clicking sounds, and I eat one ice cream. You can also have your child close his or her eyes and describe what he or she sees, hears, tastes, and touches. Encourage her or him to use number words.
Go for a short walk around your neighborhood. Choose one sense, such as hearing, and ask your child to focus on that sense. Have her or him name the sounds he or she hears as you point them out. Count the number of sounds you hear. On the return trip, choose a new sense and continue the activity.
