Square Deal

Square Deal is a Grade 8 square-root strategy game built around getting as close as possible to a target value. Players collect cards that increase or decrease an accumulated number, then the Joker ends the round and everyone finds the square root of the value they have built. Calculators may be used for the square-root step, so the mathematical focus includes comparing exact squares with decimal approximations.

Use it in a small group when students are distinguishing square roots from their decimal values and estimating reasonableness. The target comparison gives students a practical reason to interpret the calculator result rather than copy it mechanically.
