This activity, geared towards grade 7/8 math on estimating square roots, will sure keep the students engaged and excited to land on the few surprise numbered boxes that will provide them with a riddle to solve among the boxes that contain estimating square roots questions. For each question, there is a number line provided along with the list of perfect squares to help the students solve the questions. These can be easily removed to make it more challenging, if needed. Play it in present mode to take advantage of the interactive features to move to the question when you click on each numbered box or to move back to the home page after the question is completed by the students. I have played this game in the class using 2 methods:

1) I would roll an online die in front of them, and go off that (similar to snakes and ladders). The students would then all try to solve the question and display their answers to me on their individual mini whiteboards

2) Students would randomly choose any number they want and solve it on their whiteboards

The students were very engaged and super anxious to land on the numbered boxes that had riddles behind them to give them a short break from square roots.
