Written by Adi Ackerman, Head Teacher

Percent of change compares the amount of change to the original amount, so a change from 38 to 53 is an increase of about 39.5%. There are 15 sheets for 8th grade here, each with an answer key. Find the Percent Increase and Find the Percent Decrease build the core skill, Percent Change From Tables and Graphs reads sample data, and Markup and Markdown Problems and Percent Error Problems apply it. Five sheets, starting with Find the Original Price After a Discount, work backward to the amount before a change.
