What's Inside

This resource contains a three-page PDF with 22 problems for adding linear expressions. The pages are structured by difficulty: foundational skills (Part 1), negative coefficients (Part 2), and an extension challenge (Part 3). A complete answer key is included for efficient grading and student self-assessment.

Three Levels of Practice

This worksheet has three sections to support a range of learners. The versions are in a single, ready-to-print file.

• Below Grade (Part 1): Focuses on combining like terms using positive integers. The 8 problems provide a scaffolded entry point.
• On Grade (Part 2): Aligns with the 7th-grade expectation of working with rational coefficients. The 6 problems require students to add expressions involving negative integers.
• Above Grade (Part 3): The extension challenge is for students ready for more complexity. These 8 problems incorporate multiple variables, fractions, and decimals.

Standards-Aligned for Your Classroom

This worksheet is directly aligned with the following Common Core standard for 7th-grade math:

• CCSS.MATH.CONTENT.7.EE.A.1: Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.

The standard code can be copied directly into lesson plans or curriculum mapping tools.

Classroom Implementation Ideas

Use this resource before, during, or after instruction on combining like terms. Assign Part 1 as a warm-up, Part 2 for independent practice, and Part 3 for early finishers or homework. As a formative assessment, observe where students struggle; difficulty with Part 2 may point to a need to review integer operations. The worksheet should take approximately 25 to 40 minutes, depending on the section assigned.

Built for Middle School Math

Designed for 7th-grade math students, this worksheet is also useful for remediation in 8th-grade pre-algebra or as a challenge for 6th graders. Its three-part structure provides built-in differentiation for inclusive classrooms. Pair this activity with an anchor chart that defines "like terms" and illustrates the properties of addition for extra support.

This worksheet addresses a critical pre-algebra skill identified in CCSS.MATH.CONTENT.7.EE.A.1: applying properties of operations to add linear expressions. By providing structured practice, it helps students move from concrete arithmetic to the abstract manipulation of algebraic terms. Research highlights the importance of procedural fluency as a prerequisite for higher-order mathematical reasoning. According to the RAND AIRS (2024) analysis of effective math interventions, targeted practice on foundational algebraic concepts is a key component of programs that successfully prepare students for high school mathematics. This resource provides that focused practice in a differentiated format, allowing teachers to target instruction effectively. The progression from simple expressions to those with rational coefficients and multiple variables ensures students build a robust and flexible understanding of combining like terms, a skill essential for all subsequent algebra coursework.
