Keep kids thinking and using their minds - all while being entertained with the #1 educational bestseller Brain Quest! Written by teachers across the country, each workbook is written in consultation with an award-winning teacher from the Brain Quest Advisory Panel who specializes in that grade level and its core curriculum. It has become loved by parents and their kids. Each box comes with two decks of cards filled with 750-1,000 questions that apply to one-year age range (preschool, 5-6, 7-8, etc.). Questions are on one side, answers on the other, so kids can play alone or with friends and family. The set is good for reviewing information learned this year and can also act as a preview for the next grade. Bring Brain Quest on family trips, car rides, to restaurants or anywhere there might be some down time.
