# 94: Pixel Power

Math Mini Sparks, Uncategorized

Pixels are the smallest unit in a digital display. Up to millions of pixels make up an image or video on a device’s screen. Each pixel comprises a subpixel that emits a red, green and blue (RGB) color, which displays at different intensities. In this mini spark, you will learn about the basics of pixels and pixel colors.  

Spark your math thinking!

1. Start by taking out your math notebook or opening your math mini spark doc.  Put the date at the top and put the title of this mini spark. Record all of your work on this page.

2. Use this slideshow of images, which zooms a picture of raft. The final slide shows that the entire photo is actually made from individual squares of color. How does looking at these pictures help explain creation of the digital images that you see? What other images might you see today that are made from pixels?

 

3. Watch these two videos. The first video is a reminder binary numbers. It will help to see this before watching the second video. Take notes as you watch both videos.

4. After watching the second video answer these questions in your notebook. What is the RGB name for turquoise? How does a computer name turquoise? Draw the math steps that were used in the video to explain how a function is used to filter an image.

5.  Share your math mini spark recording page with your teacher/EY coordinator.

#90: A Ridiculous, Long Way to Find Out the Day of the Week You Were Born

Math Mini Sparks

Do you know what day of the week you were born on?  If not, you could…

  1. Ask your parent(s)/guardian(s) if they remember the day of the week.

  2. You could “Google”: What day of the week was May 16, 1975 (that’s my birthday)

OR

You can do this ridiculously long way…which is more fun IMO!

Spark your math thinking!

1. Set up your math mini spark recording page: #90: A Ridiculous, Long Way to Find Out the Day of the Week You Were Born

2.  Follow the steps. If you would like to see an example of the steps, scroll down to the bottom of this post.

Step 1: Take the last 2 digits of the year in which you were born.

Step 2: Divide that number by 4 and ignore any remainder.

Step 3: Add the day of the month to the answer from step 2

Step 4: Add the month’s key value to the answer from step 3.

January and October:Key Value = 1

February, March, and November: Key Value = 4

April and July: Key Value = 0

May: Key Value = 2

June: Key Value = 5

August: Key Value = 3

September and December: Key Value = 6

Step 5: Subtract 1 for January or February of a leap year.

Step 6:

Add 0 if the date is in the 1900s

Add 6 if the date is in the 2000s

Add 4 for the 1700s

Add 2 for the 1800s

Step 7:  Add the last 2 digits of the year.

Step 8: Divide by 7 and take the remainder.

Remainder 0 is Saturday

Remainder 1 is Sunday

Remainder 2 is Monday

Remainder 3 is Tuesday

Remainder 4 is Wednesday

Remainder 5 is Thursday

Remainder 6 is Friday

3. Now double-check your work by searching on Google!

#88: EWeek

Math Mini Sparks, MS Learning Opportunities

Calling all FUTURE ENGINEERS…Every year in February we celebrate EWeek. No matter what month it is, you can dive into this engineering career study and learn more about what types of work each engineer does to help our world.

Spark your math thinking!

  1. Set up your math mini spark recording page: #88: EWeek

Hydraulic engineering is a subfield of civil engineering that centers around the transport and management of water resources.Hydraulic engineers design things like channels, canals, dams and levees. They must consider many factors before beginning a project, including the collection, storage, flow, measurement and use of the water, in order to ensure its control, safety and cleanliness

Geomatics engineers collect data and then analyze and interpret it to find solutions  Geomatics engineering plays an important role in construction, transport, communication, mapping and research.

4. Choose one engineering type and work on two (or more if you want) of the problems from the problem set.

#85 Spreadsheets and Mean Absolute Deviation (MAD)

Math Mini Sparks, Uncategorized

Mean Absolute Deviation (MAD) is how far, on average, all data values are from the middle. To find the MAD of the you can follow 3 easy steps:

  1. Find the mean of the values.
  2. Find the distance of each value from that mean (subtract the mean from each value, ignore minus signs which is also the absolute value)
  3. Then find the mean of those distances

For this Math Mini Spark, you’ll be finding the MAD on a spreadsheet.

Spark your math thinking!
