Ninth graders learn to rearrange literal equations — formulas with several variables — to solve for any one variable, a skill used constantly in science, geometry, and real-world formulas.
Students will be able to…
The formula A = l × w finds area. But what if you know the area and length and need the width? You rearrange the formula to solve for w. How?
Project each item and have students rearrange the formula. The tool explains isolating a variable with inverse operations.
Tap any phase to open the teacher moves and student actions.
