Rules for Risk: I usually have my students start with 10 points, but this can be changed to fit your class. The teacher will ask a question. Students must write their answer in the first column. In the second column, they must write the number of points that they would like to risk. This number must be less than or equal to the number of points that they currently have. When the answer is given, they either add or subtract the points that they risked onto their point balance.
This resource includes questions to review fractions and intervals of time.
