FAQs

What is the focus of percentage change for 8th graders?

In Grade 8, students move beyond simple applications to solve more complex problems. This includes finding the original amount given the final amount and the percentage change, and dealing with successive percentage changes (e.g., a price is marked up by 20% and then discounted by 10%).

How can I teach students to find the original amount?

This is a common challenge. Teach students to set up an algebraic equation. For example, if an item costs $55 after a 10% increase, they can write the equation 1.10x = $55, where 'x' is the original price. Solving for x reinforces the connection between percentages and algebra.

What's a difficult concept for 8th graders related to percentage change?

Students often struggle with problems involving successive percentage changes. A common mistake is to simply add or subtract the percentages. For example, they might think a 10% increase followed by a 10% decrease returns to the original value. Use a concrete example with a starting value of $100 to demonstrate why this is incorrect.

How does this quiz support 8th-grade learning goals?

This quiz provides practice with the complex, multi-step problems characteristic of 8th-grade math. It helps students prepare for pre-algebra and algebra by strengthening their ability to work with variables and solve equations derived from real-world percentage scenarios.

How can I use this quiz in my classroom?

This resource is available as a printable PDF, perfect for focused, off-screen practice. After students complete the quiz, you can use the Wayground for Teachers mobile app to scan and grade their submissions efficiently. An answer key is also provided for manual review.

How can I support struggling students with these 8th-grade concepts?

For complex word problems, Wayground's digital format allows you to enable Read Aloud for individual students. You can also create a scaffolded version of the quiz by removing some of the multi-step problems or providing hints for setting up the initial equations.
