Data Project – Using Data to Make a Decision

All of you have a spreadsheet of data collected. Some of you have analyzed it already. You need to use the data to advise what size would be the correct size for your product.

Here is a template keynote for a presentation for you to advise what size your product should be based on your data and your analysis.

Photos will help us to understand your design and your method of measurement

The rule of 5 says No More Than 5 Things on a Slide. This includes headings, photos, captions, text bullets, etc  Make your slides visually simple and easy to understand. Insert an additional slide if you have more to say. No animation in your show..

Last Unit Test on May 12/13

The unit is about collecting, displaying and analyzing data.

Frequency tables, lineplots is where we began. Both of these show frequency

Measures of center (mean, median, mode) represent what is typical, normal, expected in a data set. This is a review of 5th grade material. Be sure that you can find a missing value given the mean.

We added outlier to our tools. We saw the effects of outliers on measures of center. Be prepared to explain how outliers affect the measures of center and what to do about it.

Then we moved to bigger data sets and found histograms to be useful as we can group data into intervals

We explored the spread of data, moving beyond the range to the boxplot and the interquaterile range (IQR).

Places to review:

ch6 study guide pg 332, 4 to 9; ep12 ch 6 #1 to #9

IQR and boxplots are in the green book only pages 586 to 589. other review material is here: boxplot practice

IXL has data display questions cc3, cc4, cc12, cc13, cc19. Mean, median, mode, range practice is dd1,dd2,dd3

Investigation

Task

Alexis needs to paint the four exterior walls of a large rectangular barn. The length of the barn is 80 feet, the width is 50 feet, and the height is 30 feet. The paint costs $28 per gallon, and each gallon covers 420 square feet. How much will it cost Alexis to paint the barn? Explain your work.

Volume and Surface Area

Design a 1 Liter Container

  • With a partner, choose a product for which you will design a container . Spaghetti will have a much different container than chocolate chips!

 

  • Determine a shape that is appropriate for your product. Please use a rectangular or right triangular prism.

 

  • Make a sketch. Check dimensions will hold 1 liter.

 

  • Build the net for your container using 1 cm graph paper. If you have time you can design the logo or other artwork for your container.

 

  • Submit your partner package model with individual:
  1. Your nameand class
  2. a list of the dimensions of the product
  3. your calculations showing that the volume is one liter.
  4. Your calculations showing the total surface area.
  5. A reflection on your process of choosing this shape. What considerations did you undertake to come to your design?

 

 

Why do you think package designers often make containers that require more material to make?

Wed/Thurs/Fri/Mon/tues/wed/thurs

Learning Target for Wed march 15, Thursday March 16th is a review of quadrilaterals and finding area.

You need to know: quadrilaterals, parallelograms , rectangles, squares, rhombus, trapezoid, obtuse. acute, congruent.

We will be investigating what we know about area and using it to find the area of rectangles (review), parallelograms and triangles.  We will use 5 identical rectangles of grid paper. and use them as follows.

1. We use to demonstrate the area of all the rectangles. 2. we make into a parallelogram and work on the area. 3. make a different parallelogram and work on the area. We make hypotheses about calculating area of a parallelogram and test them. 4. and 5. are made into parallelograms and then cut in half ot form triangles. We make and test hypotheses about calculating the area of all/any triangles. This is a hands on investigation and anyone who misses it needs to do it during the first HOT after spring break.

Homework IXL AA8, AA9 – from last week’s graphing lesson

Learning Targets for Friday 18th, Monday 21

Today we use the knowledge of area of quadrilaterals and triangles gained in last class to find areas and to “de-compose ” complex figures into quadrilaterals and triangles to find the total area. its a practice and work day.  We will investigate number sense and changing dimensions affect on area with a patty paper activity.

Classwork- do either a or b:

A: ch 10-1 page 536: 8, 15, 18, 19, 10  page 542/543 do 11,8, 17, 18, 28,29,30

B: Green book page 410, 411 # 10, 12,15,17, 21 24,25,26, 27, 29,30,(31 is a challenge question and is optional)

Homework IXL bb23, bb24

Learning Targets for Tuesday, March 22,   Wednesday, March 23

Volume of cubes,  rectangular prisms and right triangular prisms.

We start with understanding the above terms. https://www.mathsisfun.com/definitions/rectangular-prism.html will help. Be sure you understand that volume has 3 dimensions so units are cubed or to the third power. units x units x units. Then do the volume task below. be sure to show all work and explain.

volume task

homework IXL bb26 and bb 36

th, Thursday March 24th,  NO MATH CLASS ON FRIDAY MARCH 25 TH DUE TO FROG DAY

No homework, Rest and Relax over spring break!

Nets are flat shapes that fold into 3d shapes. We will work on nets and then we will calculate the surface area of cubes, rectangular prisms and right triangular prisms. Try to discover which nets will form a cube in the lesson link below.

math-g6-m5-topic-d-lesson-15-student

Then trace a small object and try to make a net that will the object. A small book should be quite doable. We will not be doing any cylinders (that’s next year) but you may want to try a triangular prism. The surface is the total area of all the faces. Find the surface area of your net. bring your net and your calculations of surface area to class after the break

I’m in Puxi at a math meeting.

We are spending up to 15 minutes on  finishing the math blog post for SLC’s. Everyone should have their evidence, their algebra movie, posted and a reflection that includes: what the evidence shows about your learning, the process of your learning, and how the movie demonstrates your learning. I would add that you should think about why I asked you to write a two step problem instead of simply assigning you a problem to solve. (HInt: What’s the hardest part of algebra and why?)

then move to the Coordinate plane practice with cartoons. You will be given a list of points and instructions. When you plot the points and follwo the instructions, picture will emerge. If you have time you can decorate the image. The most appealing ones will be displayed. Hint: lightly mark the units on the x and y axes. This is speed up your work. You will probably want to erase the unit numbers on each axis when you have completed the picture if they detract from your design.

The cartoon takes care and attention and there may not be anyone finished early but those that do may begin IXL A5, A6

For strings students and others away from school…

A number of students are out with on a string strip to Guangzhou. Here is the work for Thursday and Friday.

Now that we know about negative integer operations and we are able to use the coordinate plane, we are going to do some graphing of algebraic solutions. (graphing linear equations)

Read REd book ch 13-2, pg. 702, 703 for background. The idea is to use values of x to find solutions for the equation which are y values. Do pg 704,705 odds 11 to 29, do all 30 to 37.

You are asked to substitute a value for x and find the resulting value of y. You are asked to make a table of x,y values. You are asked to graph those x,y values. Your graph should be a straight line.

If you are unable to do these the assignment above correctly,  plan on HOT Thursday March 17th.

Note Change the word ‘graph’ to sketch in question 31. Graphng says accuracy and its not going to be possible to graph #31 with values like 273.  Instead make a sketch with each grid =50 degrees.

Homework: IXL W2, W5 both of these are coordinate plane practice.

Anyone having difficulty with integer subtraction should use virtual manipulatives http://nlvm.usu.edu/en/nav/category_g_3_t_1.html
