Class Topics: 03.01.12

In EDM today, students continued their work with Pre-Algebra skills by discussing Lesson 1.8: Graphing on the Coordinate Plane.  Before beginning the lesson, students asked clarifying questions about last night's homework since Lesson 1.7 was self-directed.  This lesson ties in nicely to some of our previous work with ordered pairs (x,y) and from yesterday's lesson on solving for y by using substitution.
Our Learning Intentions for today:

• I will be able to identify the x and y-axis on a coordinate plane.
• I will be able to give the coordinates of a specific point on a coordinate plane.
• I will be able to graph the solutions to a given equation when the x value is listed.

In class, students...

• constructed on coordinate plane on graph paper and plotted ordered pairs generated from a given equation.
• collaborated with peers to compare and check answers.

For Evening Practice, students CAN...

• complete Reteach and Practice 1.8.
• complete the two Khan Links assigned on Monday that are due on Friday.

In Pre-Algebra today, students prepared for their Chapter Seven Mid-Quiz by working with proportions.  During the lesson, students were introduced to setting-up proportions and utilizing the cross product method to solve for missing values.  Lesson 7.4: Solving Proportions, modeled several examples that students were able to view and discuss.  

Our Learning Intentions for today:

• I will be able to determine whether two ratios are proportional using the cross products method.
• I will be able to apply the use or ratios and proportions to solve problems such as the one listed below.
• A mixture of fuel for a certain small engine should be 4 parts gasoline to 1 part oil.  If you combine 5 quarts of oil with 15 quarts of gasoline, will the mixture be correct? 
• I will be able to calculate for one of the four missing numbers in a proportion by using the cross product method to set up a one-step equation.

In class, students...

• collaborated with a peer(s) to complete Problem Solving 7.4.
• began their Evening Practice.

For Evening Practice, students CAN...

• solve and post their response to the two blog questions posted below.
• utilize the quiz prep section in the textbook to study for tomorrow's ten question quiz.
• Robert weighs 90 lbs and sits on a seesaw 5 ft away from its center. If Sharon sits 6 ft away from the center and the seesaw is balanced, how much does Sharon weigh? 
•  In a shipment of 400 parts, 14 are found to be defective. How many defective parts should be expected in a shipment of 1000?
