Requires thinking11/19/2018 ByJoan I purchased this game as a reward activity for when work is completed. What a great choice it was! Students never realize how much planning and reasoning skills they are using. Many of my students have executive functioning disabilities and would rather jump into tasks rather than thinking first. After they lose the 1st round, they realize that they need to stop and plan to be the most efficient and the fastest. Get for groups or individual play.
