This is the set. All the workbooks were used by one child in our home, with pencil markings and stickers applied. No circling or pens were used, so it may be possible to erase and reuse them, but they will be provided in their current, filled-in state. If you are considering having your child do Kodomo Challenge, or if you'd like to use it for your child's learning, I would be happy if you could. #KodomoChallenge #KodomoChallengeJump #Jump #KidsWork #PowerUpWork #ThinkingSkillsGrowRapidly #Workbooks #MysterySolvingLight #Benesse #Shimajiro
