Mice by Rose Fyleman
Mouse Mess by Linnea Riley
Given basic parts, children can construct mice similar to those used in Lois Ehlert’s illustrations and talk about how mice move and use their senses, what they eat, where they like to live, etc.
Or try some of the activities at http://www.preschool-plan-it.com/mice.html.
Collect and show pictures of animals in the rodent family. Talk about how they are the same and different.
