In this Grade 4 lesson from enVision Mathematics Chapter 6, students learn to solve multi-step problems by drawing bar diagrams and writing expressions and equations with variables. Using real-world scenarios involving ticket prices, egg cartons, and quilts, students practice identifying hidden questions and breaking complex problems into sequential steps. The lesson also introduces evaluating reasonableness by comparing calculated answers to estimates.
Section 1
Solving for an Unknown in Multi-Step Problems
To find an unknown value (a variable) in a multi-step problem, perform a series of calculations based on the relationships given in the problem. For a total and parts , , and an unknown part , the equation might be structured as or .
Section 2
Multiple Solution Paths
A multi-step problem can often be solved using different, but equally valid, sequences of operations or equations. As long as the mathematical reasoning is correct, different solution paths will lead to the same final answer.
