Value Pair Match Answer Key

This worksheet turns percent change into a matching challenge where students connect each original-and-new value pair with the correct percent increase or percent decrease from an answer bank. Students work with changes such as 40 to 50, 80 to 60, 120 to 144, 75 to 60, and 64 to 80, then calculate the percent change and find the matching description in the second column. That puzzle-style format strengthens subtraction, percent increase, percent decrease, division, number sense, matching, and self-checking while giving students a reason to think about both the size and direction of the change. It is especially useful for grades 6-7 students who already know the percent-change process and are ready to use it more independently.

Targeted Skills

• Find the Numerical Change: Students first determine how much the value increased or decreased.
• Calculate the Percent Change: Learners divide that change by the original value and multiply by 100.
• Label the Direction Correctly: Students must distinguish between a percent increase and a percent decrease, not just calculate the number.
• Match to the Correct Result: Learners connect their calculation with the proper answer-bank choice.

Instructional Benefits

• Adds a Puzzle-Like Challenge: Matching keeps repeated calculations from feeling like a plain drill.
• Easy for Parents to Support: Ask, “Did the value go up or down, and what percent of the starting number is the difference?”
• Provides Built-In Self-Checking: If a calculated result does not appear among the choices, students know to revisit their work.
• Encourages Mental Reasoning: Changes such as 40 to 50 or 80 to 60 can often be understood using familiar fractions such as one-fourth.
• Works Well for Partner Practice: Students can solve independently, compare matches, and explain how they know each answer fits.

This worksheet helps students connect a percent calculation with the story the numbers are telling. Original values, new values, differences, percent increases, percent decreases, fractions, and number sense all work together as students make each match. For parents, a change from 40 to 50 is a helpful example: the amount went up by 10, and 10 is one-fourth of the original 40, so the change is a 25% increase. That reasoning makes the formula much less mysterious. In classroom and homeschool settings, this activity strengthens percent-change fluency while giving students a natural way to check their answers against the available matches.
