Disciplinary Literacy Lesson Library
The Disciplinary Literacy Lesson Library provides support for teachers as they learn and implement disciplinary literacy strategies in The Number System.
All lessons in the library have been classroom tested by participating teachers in the IQMS research project or by IQMS Support Specialists. Additional lessons and other resources, such as professional development modules and other tools, will be added to the virtual library throughout the project.

Overview

7.NS.2
7.NS.3 

In this introductory lesson, students learn to draw a model for multiplying integers through an inquiry lab, share their models in small groups, and reflect on the application of an algorithm to multiplication of integers.

7.NS.1
MP.3 MP.6 MP.7 

During this lesson, students will learn the value of the mathematical practices in applying their understanding of adding and subtracting rational numbers. Students will read an article about rational numbers and use the GIST strategy to formulate a definition for rational numbers.

CCSS 8.NS.2
CCSS 8.EE.2 

In this lesson, students will explore numbers that fall between perfect square and cube roots to begin laying a foundation for further study of rational and irrational numbers.

7.NS.1


This introductory lesson introduces the concept of subtraction as addition of the additive inverse. Students will use number lines and two color counters to find the difference between two integers.

7.NS.1a
7.NS.1b 

In this lesson, students will be using their understanding of integers and number lines to demonstrate opposite quantities. Students will collaborate and communicate their understanding of mathematical terminology through realworld contexts. By the end of the lesson, students will make conclusions that opposite quantities add to make zero.
