These cute little booklets go anywhere, anytime and review basic skills and concepts at each grade level in the areas of mathematics, language arts, science, and social studies. At just 4.5" x 4.5" (but almost an inch thick!) they contain 200 tear-off pages and are portable enough to throw in your purse. I know I'm a little strange, but even as a child I would rather have practiced skills or learned something than doodled around with those "fun activity pads" that seemed to follow us around on car trips. Know-It-Alls are educationally superior, have great variety, and would have been much more appealing. Each page has just one activity. My review copy is a 5th grade Know-It-All pad. In it, you get to compose haiku, learn about spiders, label maps, practice fractions, order events on number lines, identify parts of speech, match famous quotes to their speakers, identify advertising propaganda, learn about time zones, and on and on and on for 200 glorious pages. I can see these coming along with us on our next trip - along with a set of colored pencils. Another suggestion would be to use several pages per day during the summer. Answers are included.
