3/24 Tech day

Today is a math technology day.  Have your notebooks out so that Mr. R can check your R/P

Activity #1:  Marbleslides (y = mx + b)

• Go to student.desmos.com
• Class code: W9SY
• Enter your name
• Read all directions carefully and have fun!

Activity #2:  Play a math game (list of games in Google Classroom)

Have a great Spring Break!

3/23 Lesson 7.2.4

No computers today.

1.  Warm-up:  

What relationship does slope have to the rule y = mx + b?  

If you know the slope of a line, what other information will you need to know in order to write a rule?


2.  Lesson 7.2.4  More About Slope

• Objective:  I will describe the type of slope (positive, negative, no slope) of a given line.
• Today you may choose to work individually or with your team
• Your task is to complete Problems 67 through 70
• Problem 70 requires you to draw a graph on graph paper, draw a line of best fit, and find a rule for the line of best fit.
• If you finish early, (I imagine you should) you may work on the homework for tonight.

Homework:  Lesson 7.2.4 R/P

Mr. R will also be checking Lesson 7.2.3 R/P on Thursday

3/22 Scatter Plot Practice

1.  Today you will need a computer, 1 piece of graph paper, a ruler, and a pencil

2.  Red Vines Scatter Plot practice

Instructions:

1.  Make a small T-chart on your paper.  Label the quantities "bites" and "length (in cm)"
2.  Measure your Red Vine.  Place it in your T-chart next to 0 bites
3.  Take a bite of your Red Vine.  Measure the new length and add the data to your table
4.  Repeat step 3 until your Red Vine is finished
5.  Input your data into the Google Form in Classroom
6.  Work on "Bird's Eggs" (worksheet) while waiting for everyone to input their data
7.  Make a scatter plot (by hand) of the class data

Data Analysis (questions to be answered in your notebook):

1. Is their a correlation between bites and length?  If so, state the types of association (pages 287-288 might help you).
2. Are there any outliers?
3. Draw a line of best fit on your scatter plot
4. Find the rule for you line of best fit.  Remember:  y = mx + b,  where m is the slope
5. Use your line to predict how long the Red Vine will be if you take 3 bites.
6. Use your rule to predict how long the Red Vine will be if you take 4 bites.

3.  Finish Bird's Eggs after your analysis is complete

3/17 Lesson 7.2.1 y = mx + b

1.  Warm-up:  SBAC Practice

2.  Lesson 7.2.1  y = mx + b  Revisited

• Brainstorming:  What do you know about y = mx + b?  Why is it useful?  What is it used for?  What do each of the variables stand for?
• Read Problem 35 as a class.  Clarifying questions?
• Mini-lesson:  How to complete the process on Desmos
• The customer wants a line that grows by 2 with a y-intercept of (0,2).  The customer ordered the line y = 2x + 2
• Activity to be done in pairs, not groups of 4
• Pair #1 will do A, B, C, D
• Pair #2 will do A, B, E, F

3.  Closure (10 minutes):  Pair #1 will be Line Factory workers.  Pair #2 will be the customers.  Choose ONE of the problems that you completed.  Line Factory workers will convince the customer that their answer is correct using math evidence and justification.  Then, the pairs will reverse roles.

No Homework tonight!
