Mathematics: Algebra
Ella worked through a Grade 8 workbook lesson on solving one-variable equations, including problems such as m − 37 = 312 and 102 = 17c. She used inverse operations to isolate the variable, applying addition or subtraction to undo a constant and multiplication or division to undo a coefficient. The worksheet also included equations with decimal and fractional values, giving Ella practice keeping those numbers in her calculations. Her written steps and corrections showed her working through the problems and revising calculations as she practiced how to find a value that made each equation true.
Tips
Tips To build on Ella’s practice, invite her to explain aloud why each inverse operation keeps an equation balanced, then use a simple balance-scale drawing or household objects to model the idea. Make a short “equation scavenger hunt” with clues that lead to a hidden number, mixing whole-number, decimal, and fraction equations. Have Ella create a few equations for a family member to solve and then check each answer by substituting it back into the original equation. For a real-world connection, use a small shopping or budgeting scenario to write and solve an equation for an unknown cost.
Learning Standards
- Florida B.E.S.T. Mathematics MA.8.AR.2.1: Ella practiced solving one-variable linear equations by using inverse operations and finding the value of the variable. The worksheet’s numerical equations, including problems with decimal or fractional values, aligned with practice solving equations that use rational-number coefficients.
