Lesson 2: Operations on Integers
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 focuses on addition, subtraction, multiplication, and division of integers. There are investigation-based activities for addition and subtraction in which students use integer chips to explore integer operations in a concrete way. Once investigated, students discover the rules for adding and subtracting integers. Rules are emphasized for multiplication and division of integers. The beginning of the Cheat Sheet offers a review of the definition of an integer, shows how integers are organized on a number line, and reviews the meaning of absolute value. The practice problems offer leveled (basic and advanced) practice for each of the four operations as well as four application problems.
