Use What You Find
Look for features of the book that you can highlight in the classroom. For example, The Foot Book uses opposites and counting. You can work these two concepts into your supplemental activities. We're Going on a Bear Hunt is a great springboard for teaching vocabulary about nature (forest, river, cave, mud, snowstorm) and prepositions (over, under, through). Inside a Barn in the Country provides an obvious focus on animal names and sounds.
