### Lesson Overview

Read the book, How Many Feet in the Bed?, by Diane Johnston Hamm.

Focus on how the story lets students skip count by twos. When the father is in the bed, there are two feet, and when one more person gets into bed, there are four feet. Show that this is skip counting: if another person gets into bed, there will be six feet. Expand on this idea by asking, how many toes are in the bed? and skip counting fingers and toes by 10s. For older grades, add more people to the bed to cover adding and subtracting larger numbers. *— Ideas from *McKinney and Hinton 2010
