Several of you have caught the “Hopscotch Bug” and are creating AMAZING things in Hopscotch!  For this week’s Math Minute, you’ll be using Hopscotch to draw some polygons. Please email the EY coordinator in your building about creating a Hopscotch account.

How can you spend your Math Minutes this week?

• Start by watching this video
• Copy the chart from the video onto a piece of paper, or create the chart on your iPad.  NOTE:  You can go past a 12-sided figure if you want.
• As the video suggests, fill in the chart with the remaining information (polygon names and angles).
• Send a picture of your completed chart and a screenshot of the polygons you created in Hopscotch.

• Explore this website by increasing and decreasing the number of sides on a polygon.  Watch the angles change as you do this.  While on the website, explore and find the answers to the following questions:
  • What are regular polygons?
  • What are convex and concave polygons?
  • What are supplementary angles?  What does that have to do with this activity?
  • How did you figure out which number to enter for the degrees in the Turn Command in Hopscotch?
• Leave a comment with the answer to one of the questions above and/or post any new information you learned/observations you made.   Remember when leaving a comment to include your first name, grade, and school (i.e. Trevor, 3, Sunset).

Happy Coding!

Car brands are making impressive advances in the field of self driving cars. These breakthroughs combine advanced safety systems to help reduce driver fatigue by assisting with acceleration, braking and steering. There are also high tech adaptations that can help people with disabilities accommodate their driving needs.

Spark your math thinking!

1. Set up your math mini spark recording page: #45: High Tech Cars
2. Read this article about self driving cars. Record the level names and a short definion for each.
3. Check out this video of Sam Schmidt’s High-Tech modified corvette!  The 3 minute video is chock-full of speeds, measurements, and high-tech components!  Imagine being able to drive a car without the use of your hands and legs! On your recording sheet, document any numbers mentioned in the video (speeds, measurements, etc.).

5. Read this article to find out more about Sam Schmidt and the semi-autonomous motorcar he drove.  Write about something new you learned or a new question you have after reading the article.

6. Read about flying cars at Wonderopolis.  Make a list of 3 pro and 3 cons of having flying cars in the city you live in.

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

TO INFINITY AND BEYOND!!!

This famous line from the beloved Disney Toy Story Movies became a common phrase for children in the mid 1990’s.  But what are we really saying when we declare our desire to take off on this infinite voyage?

Spark your math thinking!

1. Set up your math mini spark recording page: #44: Infinity
2. Check out this TED Ed video on infinity.  Record 5-10 details from the video on your recording page.

3. Knowledge can be infinite!  Check out this link to expand your knowledge on this topic! Write about something you learned.

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

This mini spark is about fractions and multiplying cheese and milk.

Spark your math thinking!

1. Set up your math mini spark recording page: #42: Multiplying Cheese and Milk

2. This is a clip from my absolute favorite Home Improvement episode.  Most of you are probably too young to remember the show, but you can catch re-runs sometimes or find them on You Tube.  This particular episode is related to math and talks about some of the “crazy” rules and words mathematicians use

3.  The steps to multiplying fractions can be confusing.  Watch this video as a reminder. Do the math along with the teacher in the video. 

4. Figure out the answer to Jill’s “cheese milk” recipe:  1 1/2 lbs of cheese x 1 1/2 gallons of milk. Record the all of the math and the answer.

5. There are times when a math item can be called different names.  In the video above, they called mixed numbers, compound fractions. My favorite math word is radical! It can also be called root symbol. I like it so much I had a shirt made! Do a little research and find some math terms that go by more than one name.

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

Will future spacecraft fit in our pockets?  Learn about  this small technology and how scientists are exploring our world.

Spark your math thinking!

1. Set up your math mini spark recording page: #41: Future Spacecraft
2. Watch this video, write about some of the calculation scientist must make for these tiny spacecraft to be created. 

3. Think about the following:  NASA provides opportunities for students, researchers and industry to launch their small satellite payloads on NASA’s own launches.  What type of small satellite would you build and what type of data or experiment would you carry out if you could send a small satellite to space?

4. Read about Specific Impulse on this site.  It’s some higher level math, but try to read through it and pick out at least one new thing you can write about on your recording page.

5. Read about SmallSats and CubeSats at NASA. Record some details on your recording sheet.

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

Wait…is this a Math Spark or a Science Spark?  Math and science are so intertwined that it’s hard to tell sometimes whether you’re doing one or the other.  Many times it’s both!

This is a date calculation puzzle to try! Other date puzzles can be found at Math Mini Spark #30 and #90.

Spark your math thinking!

1. Set up your math mini spark recording page: #40: Universal Calendar Puzzle
2.  Take notes as you watch the tutorial. It is also helpful to pause the video while you are watching to do the calculations. NOTE Pause the video and calculate the date 10.19.1902.  Unpause the video to see if you were correct.

3. Please complete two date calculations of your choice from start to finish and put the date, your math and your solution on your recording page.

4. This info sheet is very helpful.  You can print it to help you do step number 3.

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