#55: Coordinate Geometry

Math Mini Sparks, Uncategorized

Coordinate Geometry is one of my favorite areas of math.  There’s just something about getting a sheet of ordered pairs and carefully plotting them on graph paper…connecting the dots to reveal a picture.  If that’s your sort of thing too, check out Option 3 below.  Happy plotting!

Spark your math thinking!

1. Set up your math mini spark recording page:#55: Coordinate Geometry

2. Learn the basics of coordinate geometry by watching this video.  Take picture notes on your recording sheet. 

3. Read about the inventor of coordinate plane geometry, Rene Descartes.

4. This video gives a musical explanation of his accomplishments.  Put together a note page about him.

5. Print out (or have your teacher print out) this project. Plot the ordered pairs on the graph paper and reveal a spooky surprise!  Take a picture of your completed drawing and send it to the EY Coordinator at your building.

6. Create your own coordinate plane art. Plot the points and connect them with the colored lines. Take a picture after you have practiced for at least 10 minutes.

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

#54: Multiplication Tricks

Math Mini Sparks

Multiplication. It is one of the four types of operations you learned in math (along with addition subtraction and division). There are many different ways to multiply numbers. However, sometimes, multiplying really big numbers can be a challenge. Luckily, there are many different techniques you can use to solve large multiplication problems.

#53: Cribbage

Math Mini Sparks, Uncategorized

My family enjoys playing pitch,  31, sevens and trash.  However, my absolute FAVORITE game is cribbage!  It involves strategy and math, which is why I like it so much!

Spark your math thinking!

  1. Set up your math mini spark recording page: #53: Cribbage
  2. Read about cribbage and record some details.
  3. What is one “thing to remember” when playing cribbage.
  4. Record this information. In cribbage, the Jokers are removed from the deck. The Ace is worth 1. The face cards (Jack, Queen, and King) are each worth 10. The other cards (2 through 9) are each worth their number value
  5. Here are some of the ways you can earn points when playing cribbage.
One of the ways to earn points in cribbage is to have cards that add up to fifteen.  In the picture below, the King and one of the 5’s make 15 so that is 2 points.  The King and the other 5 also make 15, which is another 2 points.  You might notice that there is a 5 that is face up on the deck.  This can also be paired with the King for 15 for another 2 points.  Finally, the three 5’s (2 in the hand and one on the deck) add up to 15.  This is an additional 2 points.IMG_8825When you have a pair of the same card, you earn 2 points.  The pair could be in your hand, or one of your cards could be paired with the card that is face up on the deck.  If you have 3-of-a-kind, that is worth 6 points.  In the picture above, there are two 5’s in the hand and one 5 face up on the deck.  Not only does that make 15, but it is also 3-of-a-kind which earns you 6 points.
A “flush” is when you have 4 or more of the same suit (clubs, spades, hearts, or diamonds).  If you had 4 hearts in your hand, you would earn 4 points.  If the card that is face up on the deck is also a heart, you would get 5 points.  The hand below shows 5 clubs so you would get 5 points.
Hand7
A “run of 3” is when you have 3 cards in numerical order.  You could also have a run of 4 or 5 cards.  Let’s say you had a 3, 4, 5, and 6 in your hand.  You would have a “run of 4” which is 4 points.  If the card on the deck was a 2 or 7, you would have a run of 5.  The hand below shows a run of 5.
RunOf5

6. The pictures below show several cribbage hands.  See if you can add up the points correctly!  Record the “hand #” and an explanation of the total points.

#51: Movie Math

Math Mini Sparks

Today’s age is filled with a wide variety of forms of entertainment. Television shows and movies are some of the most common forms today. Usually we don’t associate math with these however there have been some movies and episodes with a focus on a math topic. One such movie is Good Will Hunting. The movie has a particular math problem in which an MIT professor claims it took him years to solve. The problem basically is to draw all shapes that fit the description. There are ten shapes in total. MIT is one of the best universities in the world. Are you able to solve the problem that supposedly took an MIT professor a long time to solve in a day or less? Find out!

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.

Screen Shot 2015-04-28 at 9.23.47 PM

  • 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!
