4/6 Chapter 6 Rework

1.  Warm-up:  Mathematics Checklist

2.  Chapter 6 Rework

Everyone can earn back points on their test!  You are eligible to earn back half of your points by completing the rework.  You do not have to rework any problem that you scored 100% on.

To earn back points, you must rework the problem AND complete the Ninja Practice problems.  All problems must be solved correctly to earn the points.

There are 6 stations in the room, 1 station for each of the problems on the test.

Each station is being taught by a student-mentor who demonstrated mastery on the test.  This student-mentor will explain their process, and help with the rework.

After 5 minutes we will switch so that everybody (not including student-mentors) will travel to every station.

There are other experts in the room!  After the student-mentor explains their solution feel free to explain yours as well.  But, your first job is to listen to the student-mentor without interrupting (just like you would with a teacher).

The goal of this activity is to help each other understand how to solve the test problems and Ninja Practice problems.  Everyone is a teacher, and everyone is a student.  Let's work together so that we can all be successful!

Homework:  Complete the Chapter 6 Rework.  It is due on Friday (no late work accepted)

4/4 Lesson 7.1.1 Distance, Rate, and Time

1.  Warm-up:  Read the following scenario and answer the follow-up questions

George stood on the train platform and waved goodbye to his sister as she left for summer camp.  Later, as he was getting in his car to drive home, he saw a light flashing inside the train station and heard an announcement that his sister’s train had broken and was stuck on the tracks.  George had a map of the train’s route and decided to drive to where the train was stuck and pick up his sister. 

• How can he figure out where the train is?  What information would help him to figure it out?

2.  Lesson 7.1.1 Distance, Rate and Time

• Objective:  I will use proportional reasoning to solve problems involving distance, rate and time.
• Mini-lesson: Calculating Speed (think Ratey, the Math Cat)
• Outdoor lesson: Who is Faster?
• Who has a phone/watch with stopwatch capabilities?
• Partner up
