### Description

The 15 lessons in Numbers (1) provide initial instruction or intervention on numbers and operations. The first five lessons develop number sense and conceptual understandings of number operations. M1.1 Order of Operations (NOTE - THIS LESSON HAS A SYNCING PROBLEM. AN UPDATE WILL COME SOON. MUCH OF THE SAME MATERIAL IS COVERED IN A1.5 - EXPRESSIONS AND OPERATIONS) M1.2 Divisibility Rules M1.3 Properties of Addition and Multiplication and Inverse Operations M1.4 Distributive Property M1.5 Estimation The next five lessons focus on whole number operations. To deepen understanding of the base-ten number system, students perform operations involving larger numbers. As recommended by NCTM, “Students should use a variety of models and contexts when exploring whole number operations.” The lessons in this module present alternative algorithms for solving problems that involve whole number operations with large numbers. Here, the objective is not to teach the student how to perform these operations quickly, but to have them gain an understanding of the ideas behind the operations. Once they grasp the concept, the speed will come. M2.1 Large Numbers: Addition M2.2 Large Numbers: Subtraction M2.3 Large Numbers: Multiplication M2.4 Large Numbers: Division M2.5 Problem Solving Strategies The last five lessons in this group develop an understanding of the meaning and effects of arithmetic operations involving integers. Students use two types of representations – two-colored counters and number lines – to model integer concepts and problem solving with the four basic operations involving integers. The mathematical rules are then presented. M3.1 Integers and Absolute Value M3.2 Adding Integers M3.3 Subtracting Integers M3.4 Multiplying and Dividing Integers M3.5 Solving Problems with Integers Student print materials and Teachers' Notes are available for download at www.elevatedmath.com.
