In this Grade 5 lesson from enVision Mathematics Chapter 12, students learn to solve multi-step real-world word problems by converting between units of measurement such as yards to feet, quarts to cups, and pounds to ounces. Students practice converting unlike units to like units before applying formulas like the perimeter formula to find solutions. The lesson builds skills in recognizing when a conversion is needed and choosing the appropriate operation — multiplying to convert from larger to smaller units — within practical contexts like garden edging, ribbon length, and pool dimensions.
Section 1
Perform Operations with Like Units
To add, subtract, or compare measurements, they must first be expressed in a common unit. The process is:
Section 2
Solve Multi-Step Measurement Word Problems
To solve a multi-step measurement problem, first identify the units involved.
Convert all measurements to a common unit, which may require one or more conversion steps.
Then, perform the necessary calculations (addition, subtraction, multiplication, or division) to find the final answer.
Solving multi-step word problems involves combining measurement conversion with other mathematical operations. The key is to first convert all quantities to a single, common unit before adding or subtracting. This often means changing a larger unit to a smaller unit (like pounds to ounces) to make the calculation straightforward. After converting, you can solve the problem by performing the operation described in the word problem.
