You can use the Ten Little Snowman activity on Starfall.com to work on vocabulary and descriptions with your child. This is an activity where you make a snowman by picking a hat, arms, scarf, eyes, nose and mouth. Play this game with your child, taking turns describing which hat etc. to put on the snowman while the other person clicks on it so that your child can practice understanding and giving descriptions and directions. This activity also reinforces counting to ten with the Ten Little Snowman song at the end.
