Tip the beam level to solve the equation — balance the pans, solve for x, and build equal weights on both sides.
A round involves adjusting weights on each pan until the beam tips level, which requires finding the unknown value that makes both sides equal. Children practise setting up and solving simple equations and develop the solve-for-x thinking that underpins pre-algebra. Best suited for Grades 4–6, or any child ready to move from arithmetic into working with unknown quantities. Teachers also use it as an interactive balance scale on a smartboard or projector — a virtual balance manipulative for demonstrating equality without any physical weights.
