Differentiated instruction at its hands-on best. Students fold, cut and tape two simply elegant (and accurate ) paper beam balances included in this book. Activity sheets prompt kids to use one balance to make quick sense of arithmetic functions and algebraic equations, and the other for a playful exploration of mass and weight. Even preschoolers will delight in age-appropriate inquiry. When you finish the unit, let students take these cheap and simple lab instruments home to wow their families. Great cross-age learning opportunities
