Objective and Summary:
SWBAT represent the sum of integers on vertical number lines and write addition equations 

Guided Practice
Mountain Climbing--Ms. Lugo went hiking this past weekend with her family around Alum Rock Park. They hiked up 2 miles before taking a lunch break. They then hiked up another 3 miles and found that there was a zip line at the top that would allow them to descend (go down) back to where they started.

a) Model the situation using the vertical number line.

b) Write an addition equation to match your number line.

CFS:
#1: Accurately models on a vertical number line
#2: Writes an accurate addition equation

Breaking the Bank--On Saturday Lesly got paid $10 for doing chores around the house. She then immediately ran over to Starbucks to buy two drinks that cost $6 each.

a) Represent the change to her money on the number line.

b) Write an addition equation in the answer box.

#1: Accurately models on a vertical number line
#2: Writes an accurate addition equation

Skill and Drill--Model the following expression on a number line and write an addition equation.

a) -5+12

CFS:
#1: Accurately models on a vertical number line
#2: Writes an accurate addition equation

b) Why did your sum for -5+12 end up with that sign?

"The sum is (positive / negative) because..."

MEDIUM Problems

Skill and Drill--Model the following expression on a number line and write an addition equation.

a) 7+(-16)

CFS:
#1: Accurately models on a vertical number line
#2: Writes an accurate addition equation

Model the sum of the following numbers then write an addition equation.

2, 1/2, -4

CFS:
#1: Accurately models on a vertical number line
#2: Writes an accurate addition equation

Analyze--Use the diagram in the SYW section.

a) Write an addition equation to represent the values on the vertical number line.

b) Which of the following expressions have a sum of -7?
Select all that apply.

You do not have to represent all of the expressions on the number line, but you can if it helps you. You can also use a different color for each expression so you don't get them mixed up

Great work! You can push yourself ahead on IXL by...

1) Working with more number lines (Search code: EM8)

2) Working on absolute values (Search code: NSB)

3) Challenging yourself on diagnostic or Algebra topics
