Use this resource, formatted for interactive notebooks, as a quick and easy reference to help students learn how to calculate percent error in an experiment. The front page of the booklet includes a tutorial on calculating percent error, and the inside of the booklet contains 6 practice problems to help students practice the skills they've learned on the front. I find that percent error is typically an easy concept for students to grasp, so this is a great, quick way to teach it. The download also includes the quick-reference tutorial sheet on it's own, perfect for upper-level students that might not need to practice but do need a reference occasionally.
This is a great low-to-no prep activity to have on hand. Just print the booklet pages back-to-back, fold, and start teaching. The download includes a 1 page teacher guide, 2 page booklet, half-sheet reference page, and a 1 page answer key.
