Lesson 1.1 - Adding Integers with the Same Sign

I will be able to model addition tasks as evidenced by use of a number line and counters.

Adding integers activity

Add yellow counters (these are positive counters)

Notes:

Sum:
Integer:

Do activity again with red counters (These are negative counters)

Discuss the following question with your table partners:

When adding two numbers with the same sign, what sign do you use for the sum?

Guided practice p. 10

Work on p. 10 independently

Class Discussion:

Your team scores -8 and -4 on the first two rounds of a game. How can you use addition to find your team's total score?

Teach adding integers on a number line that is drawn on the wall. Model first, then ask for student volunteers - these are all addition, so you should turn and face the higher numbers.

Number Line Activity

Use the numberlines at your table to model the following math problems:

8+9
0+(-12)
2+8
(-6)+(-12)
-5+(-3)

Work on the odd numbers on p. 10

Homework: P. 10 # 1-17 (in workbook)

Lesson 1.1 day 2

I can add integers with like signs using rules.

Create rules for adding integers with like signs.

Independently work on the your turn on p. 9

With a partner of your choosing, work on p. 11-12

Practice adding integers with the same sign
