Directions
Grandpappa's doorway is too narrow for the ball. Look for opportunities during your day to match size to need. Let your child find the right-sized lid for the pot you are using, or choose the best bag to carry toys to grandma's, or how big a towel he needs to fit around his teddy bear, etc. This will work best for three and four year olds if you give them a limited number (2-4) of options to choose from. As children get older, the possibilities can be more open-ended.

Talk About It
While viewing the Big Ball episode, you might start a conversation by asking your child: How would you help Grandpappa get his ball through the door? If you had a big ball like that, what would you do with it?

As you talk about the things on screen, you can help expand your child's vocabulary by alternating the words you use with their synonyms. In the Big Ball episode, you can say that the doorway is too narrow, thin, small or slender for the ball to fit through.
