Title: 
Integers Are Rising and Falling Everywhere! Adding and Subtracting Integers 
Overview/Annotation: 
Students will expand from the idea of not only identifying signed numbers but to use them for numerical operations. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Content Standard(s): 
MA2013(5)  18. Convert among differentsized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multistep, realworld problems. [5MD1]  MA2013(6)  8. Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in realworld contexts explaining the meaning of 0 in each situation. [6NS5]  MA2013(7)  4. Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram. [7NS1] 

Local/National Standards: 
Students will use various strategies and operations to solve problems involving real numbers. ACOS #1(Numbers and Operations) 
Primary Learning Objective(s): 
Apply mathematical calculations and reasoning to solve problems. 
Additional Learning Objective(s): 
Students will review positive and negative numbers. Students will learn the rules for adding and subtracting integers. Students will learn how to add and subtract integers using a number line. Students will be exposed to integer multiplication. 
Approximate Duration of the Lesson: 
31 to 60 Minutes 
Materials and Equipment: 
The practice worksheets can be found here: Integer Worksheets. (Choose which range of integers you want to students to practice adding and subtracting.) 
Technology Resources Needed: 
Access to computer lab Multimedia projector 
Background/Preparation: 
Students should be able to interpret a number line. You will need to install the Java application in order to view videos, applets, etc. 
Procedures/Activities: 
2.)To expand connection to the lesson, have students watch the teaching video: Adding and Subtracting Integers.
After the video, group the students in male and female pairs. Pass out the 'Integers Worksheet'. Students work together to complete problems.
Special Note: The assignment may be modified at your discretion.
3.)Students go to the board to display the answers to the problems. Observe student responses. Answer any questions or comments.
4.)Students go to the computer lab (Math Lab) for progress check. The teacher may determine which scores meet mastery levels for the addition and subtraction concepts.

Assessment Strategies: 
Math Lab Students check their comprehension and skills with the following selfassessment application. SelfAssessment 
Extension: 
Students will use integer addition to explore modular arithmetic (time) and discover any patterns that result. ArithTicToc 
Remediation: 
Students practice adding and subtracting integers using a number line. Integer Practice
