Change Checkup

This worksheet asks students to become percent-change checkers by deciding whether each completed statement is true or false and correcting any statement that does not work. Students inspect changes such as 40 to 50, 80 to 60, 50 to 65, and 125 to 100, then verify both the direction of change and the stated percent. The activity strengthens percent increase, percent decrease, subtraction, division, original-value reasoning, error analysis, and mathematical judgment while helping students understand that a correct percent-change answer has two parts: the percentage itself and whether the value increased or decreased. It is especially useful for grades 6-7 students who know the percent-change formula and are ready to prove they can recognize and repair mistakes.

Learning Goals

• Check the Direction of Change: Students determine whether each pair represents an increase or decrease.
• Verify the Percent: Learners calculate the amount of change and divide by the original value to see whether the stated percentage is correct.
• Correct False Statements: Students replace incorrect percentages or labels with accurate ones.
• Use Reasonableness: Learners estimate whether the percentage seems believable before completing an exact calculation.

Classroom & Home Use

• Easy for Parents to Discuss: Ask, “Did the number go up or down, and is that change really this percent of where it started?”
• Builds Self-Checking Habits: Students practice reviewing completed work instead of assuming the written answer must be right.
• Targets Common Mistakes: The format exposes errors involving wrong denominators, incorrect direction labels, and miscalculated changes.
• Useful for Quick Assessment: Teachers can see whether students understand the full percent-change process.
• Flexible for Review: The worksheet works well for homework, intervention, centers, assessment, or homeschool lessons.

This worksheet helps students become stronger mathematical judges instead of simply stronger calculators. Original value, new value, amount of change, percent increase, percent decrease, division, and error analysis all work together as students inspect each statement. For parents, the simplest check is to go back to the starting amount: if 40 becomes 50, the increase is 10, and 10 is one-fourth of the original 40, so the change is 25% rather than 20%. In classroom and homeschool settings, this activity builds accuracy, confidence, and the habit of checking whether a percent-change result actually makes sense.
