Math - [Lesson 2.11]
Teacher: Mr. Kovalik (408) 314-1092

Objective and Summary:
SWBAT write equations for real world situations by using the sign rules for multiplication

Exercise--A marathon runner lost 7 pounds per month for four months. What was the total change to her weight?
Write a multiplication equation to represent the situation.

CFS:
#1: Identifies appropriate signs from context of the problem
#2: Accurately represents equation and its product

Journey--Sometimes Mr. Kovalik takes the Cal Train up to San Francisco. Every time he rides the Cal Train, he has to pay a $4 fare. If he goes up to the city a total of 13 times, represent the change in his money with a multiplication equation.

CFS:
#1: Identifies appropriate signs from context of the problem
#2: Accurately represents equation and its product

Oops!--Mr. Kovalik removed six $3 deductions from Danna's Prize Check because they were inputted on accident. What is the change to Danna's Prize Check total?
Write a multiplication equation.

CFS:
#1: Identifies appropriate signs from context of the problem
#2: Accurately represents equation and its product

MEDIUM Problems

+ or =??--Use our rules for signs to determine if the product is positive or negative.

3(-10)
-2\cdot20
-10(-9)
9\times(-7)
100\cdot80
-1.5(2)
-2.75(-4.5)

Positive product
Negative product

Traffic Troubles--Ms. Paul has gotten five parking tickets that are all for $18.72. Write a multiplication equation to show the change to her bank account.

CFS:
#1: Includes correct values from the equation
#2: Word problem makes logical sense for positive/negative values

Skill and Drill--Complete the table below by typing directly into Formative's SYW.

SPICY--Try if you have time.

BE CREATIVE--Write your own word problem that can be represented by the equation, 12(-3)=-36

CFS:
#1: Includes correct values from the equation
#2: Word problem makes logical sense for positive/negative values

Mystery Pair--Two integers are multiplied and their product is a positive number. Which of the following could have been the original pair of integers?

Select ALL that apply.

Translate--Take one of the expressions that you identified to be correct in question 8 and write a word problem that matches the expression.

If you're not sure what to write about, you can always talk about gaining or losing money.

CFS:
#1: Identifies appropriate sign rules
#2: Word problem makes logical sense for positive/negative values

Keep Pushing Ahead--Go down to the Finished Early? section and get all of those skills up to at least 85.

Then you can do more challenge IXL skills!

At the end of class, let me know how many skills you mastered here in question 10.

Nice job! This is a shorter lesson, so please do the following:
1) Practice more integer multiplication on IXL: (Search Codes: NB8, K7U, DQT)

Subtracting Integers

Understand multiplying by a negative integer using a number line

Multiply Integers

Add, subtract, multiply, and divide integers

2) Practice challenge skills like Algebra 1 or do more diagnostic practice to push yourself ahead!
