Lesson 3: Order of Operations
A Cheat Sheet is an all-in-one, single-page graphic organizer covering the big topics in the Algebra 1 curriculum. Each Cheat Sheet includes important vocabulary, key concepts, and guided examples. There is a set of practice problems included with each sheet that provides leveled and skill-based practice. Included in the download is a PDF and editable WORD version of the Cheat Sheet and Practice Problems, along with a full answer key.
This lesson explores the order of operations by breaking down each segment of the concept into an isolated step. Students will first explore addition vs. subtraction, learning that both operations are equal in priority. They then work with addition/subtraction vs. multiplication/division. The third step introduces exponents and square roots into the expressions, with the fourth and final step including various types of grouping symbols. This method allows students to master each segment of the concept in isolation so that when the pieces are put together, students will have a better mastery of the order of operations, compared to giving them the entire chunk at once. The practice problems are also isolated by skill corresponding with the Cheat Sheet. There are two higher-order thinking questions included that asks students to create problems based on a set of given criteria that requires them to use the order of operations from the inside out.
