Lesson: Add Integers Using Number Line
Lesson Objective
Lesson Plan
Standard 

6NSO.N3 Know that numbers and their opposites add to 0 and are on opposite sides at equal distance from 0 on a number line; know that 0 is an integer that is neither negative nor positive 6NSO.C9 Know integer subtraction is the inverse of integer addition; use the number line to model addition and subtraction of integers and add and subtract integers


Aim/Objective:

Key Points


SWBAT add integers using a number line
SWBAT model addition of integers on a number line 
· When adding integers on a number line: o Start at the first addend by moving from zero to that number o If adding a positive number move RIGHT that many spaces o If moving a negative number move LEFT that many spaces 

Assessment:


Exit Ticket: 1. Corazon used the number line model shown below to help her write a true number sentence.
Which of the following could be Corazon’s number sentence?
Use the number line below for questions 2 and 3.
2. 6 + 10
3. 5 + (9)


Lesson


Do Now:
Intro/Direct Instruction:
Teaching Points: / Students take notes · We can use a number line to add integers
· Always start at zero. Then move to first addend
· If the second addend is positive move RIGHT that many spaces
· If the second addend is negative move LEFT that many spaces
· The space you land on is your sum
· Demonstrate with – 5 + 8
· Model how to draw this on a number line. (start end of arrow at zero, move to negative 5 with arrow. Draw new arrow on top of negative 5 and move 8 spaces to the right)
· Model: 2 + 5; 9 + 3; 5 + 7
Guided Practice
o Give students number lines and a hershey kiss. Have them demonstarte the following problems (5 + 5; 8 +2; 4 + 8 )
Independent Practice:
· Students practice adding and modeling integer addition on worksheet
Closing
· Review how to model addition on the number line
· Adding a positive means moving (RIGHT) on the number line
· Adding a negative means moving (LEFT) on the number line
