My 5 year-old loves making books on all kids of subjects and I like the fact that it improves his writing, increases his knowledge and teaches him to finish what he had started.
To do this homemade book about the solar system, we researched the planets, remembered what they looked like and memorized a thing or two that made each planet unique. Then, my son drew each planet in his book, using pastels. Finally, he wrote a sentence or two about each planet next to its drawing. We used a book we had purchased form Bare Books as a base for my son’s work.
