GoalSolve equations including symbols representing variables.
Builds UponStudent Book pages 2627Instructions for UseAlgebra Balance Scales allows students to solve simple equations through the use of a balance beam. To use Algebra Balance Scales, click and drag unit blocks and Xboxes from bins to the balance beam pans to represent the equation. When the beam balances from the given linear equation, students can perform any arithmetic operation. To keep the beam balanced, the same operation must be done on both sides of the equation. The goal, is to get a single Xbox on one side, with however many unit blocks needed for balance on the other side to find the value of X. Once the equation is represented, click the 'Continue' button. Click on any of the other buttons, to add, subtract, divide, or multiply. Do the same operation to both sides of the equation. In the text box, have students input what they want to add to or subtract from both sides, and click the Go! button. Students can, for example, subtract 2X from both sides, if there are two Xboxes on both sides. Multiply or divide only by numbers, and only if the operation can be done in whole numbers. The equation is updated with each operation. When students have a single Xbox on one pan and blocks on the other pan, the equation displays the solution.
