I loved these books growing up. We’d always have one I could work on over the summer and just here and there through the school year. Right now you can score the Brain Quest Workbooks for as little as $6.29! They also have other great ones like a preschool activity book with 75 games, the brain quest cards (which are great for longer car rides) and so much more. Keep in mind, Amazon pricing can change at any time! Don’t wait to purchase this deal or it might be gone when you come back!
