Resources
Excellent authors of books for the primary level include: Leonora and Arthur Hornblow, Illa Podendorf, and Millicent Selsam. There are many thematic units that integrate science with literature and writing that are on the market. Authors of books that can be used either on the primary or secondary level include: Robert Wood and Janice VanCleave. Dover and Bellepheron coloring books are excellent resources as are many reproducible materials from a variety of publishers including Instructional Fair, Creative Teaching Press, Frank Schaffer, and many others.
There are many excellent resources that can be accessed over the internet. Following are some of the links that I have found that you may find very beneficial. Of course, these links will take you take you to other sites. Have fun.
