Matching Classical Achievements and Inventions practice for a high school world history class. Each problem matches an answer in the design grid above, and as students color in their answers a symmetrical pattern appears. If the pattern looks right, the work is right. That makes it easy for students to catch their own mistakes and easy for you to spot-check at a glance. Works well for classwork, homework, additional practice, extra credit, and sub plans. The finished designs can also be cut out and pieced together into a class quilt for a bulletin board. The PDF includes the worksheet and answer key.
