Missing Factors PEMDAS

Students complete each expression by supplying the missing factor that makes the equation true. To solve each problem, they must evaluate the existing operations using PEMDAS and determine which number completes the equation correctly. This activity strengthens algebraic reasoning and helps students internalize the structure of equations. Learners practice isolating unknown values and understanding how multiplication and subtraction interact in multi-step expressions. The worksheet promotes critical thinking and is ideal for students beginning to transition toward solving simple equations. It can be used in small groups, centers, or skill-building sessions.
