Don't forget khan academy or sumdog are free. We're slowly working through the Usborne Interner linked Encyclopedia of World History with a pencil, paper, and 3-ring binder. You read a two page spread, write a summary, and draw a picture about it. It goes in a 3ring binder full of page protector pockets. I don't know how long it will take us to get through the book (at least a year, maybe a few years). We're not hurrying. It's outlining, note-taking, summarizing, and an intriduction to World History. When it's over my kid will have made a keepsake, his own book of world history. He'll be ready to study them more in depth after this, his first exposure to world history. (idea from the well trained mind).
We're not going to do it this year, but summer before last we signed up for SuperCharged Science with Aurora Lippor. We did the "robotics" which was more like circuits, but did make moving projects. We're not doing it this summer, but my son is looking forward to taking her chemistry section soon. I recomend Supercharged science. I bought everything on the robotics list from radio shack and the grocery store and put it in a bucket. I had my son watch the video and pull out the right parts and then I helped him do the projects.
