  1. Example of Using “Steps in a Procedure” Question Exploration Guide 1 What is the critical question? What is the algorithm and an associated acronym for multiplying binomials? What are the key terms and explanations? 2 A set of steps for performing a math operation. A mathematical expression comprised of two terms joined by a plus sign (+) or a minus sign (-). A word formed by the first letters of different words. Algorithm Binomial Acronym What are the supporting questions and answers? 3 What is step 1? What is step 2? What is step 3? What is step 4? What is step 5? F = Multiply the First terms in each binomial (2x-y)(3x+2y) 2x * 3x = 6x2 O = Multiply the Outside terms in each binomial (2x-y)(3x+2y) 2x * 2y = 4xy I = Multiply the Inside terms in each binomial (2x-y)(3x+2y) -y * 3x = -3xy L = Multiply the Last terms in each binomial (2x-y)(3x+2y) -2 * 2y = -4y2 S = Set up and Summarize the answer. 6x2 + 4xy-3xy - 4y2 = 6x2 + xy - 4y2 The algorithm contains 5 steps involving multiplying the terms in a sequence and summarizing the answer. The word “FOILS” is an acronym that can be used to remember the steps. 4 What is the main Idea answer? 5 How can we use the main idea again? Solve this new problem using the FOILS algorithm. (3x + 4y)(2x + 2y) Explain how the FOILS acronym helps you as a learner. Create your own memory device for another math algorithm. Is there an Overall Idea? Is there a real-world use? 6
