Barker Creek's Draw-Write-Now series is great too. We used the Animals of the World Part 2 book today during our lesson. I especially like the wide variety of subjects covered in the Draw-Write-Now set. There are books that show how to draw all kinds of animals, holidays and celebrations, important historical figures, geographical locations, and American symbols.
We explored a variety of procedural texts on drawing. Then we followed the directions in the Draw-Write-Now Book for the lion. When we were finished drawing our pictures we wrote our own procedural text for what we did.
