Sierpinski Gasket -- Math Art -- Fractals

 

Today I am going to share some fun math art looking at a famous fractal--the Sierpinski Gasket or the Sierpinski Triangle. It is a perfect fractal to have kids create and goes well with geometry lessons. A fun way to introduce it and create it is the Chaos Game. Here is a video showing the Chaos Game with a triangle, square, and pentagon. With the triangle the Sierpinski Triangle will appear with enough iterations of the game. The rule as explained in the video is to begin with a random point. Then randomly choose a vertex. Connect your point to the vertex and find the midpoint. (Erase the line.) The midpoint is your new starting point. Repeat. This is a game you could easily play in a class as well. Don't watch the video first though. 

Discovery Math Activities Round-Up

I saw a meme on Facebook that says: "Think you're bored? When Sir Isaac Newton invented calculus it was during the plague. Do you have any idea how bored you have to be to invent calculus?" Now the truth is Gottfried Wilhelm Leibniz, a German mathematician, published the same discoveries around the exact same time as Isaac Newton. Each mathematician claimed the other stole his ideas, but it is believed that both actually discovered the same thing separately around the same time. (For more about Isaac Newton click here and I share a little more about both men here.) 

2 New Picture Books Perfect for Women's History Month

Disclosure: I was sent copies of these books in exchange for honest reviews. All opinions are my own.

How are you surviving this crazy new social distancing? School buildings here are closed until at least May 4 and now lessons are on-line for all students. It is a strange time. I have several friends who are nurses at hospitals and both have told me about the lack of face masks. Although I believe the supplies are slowly coming I decided to do my part and make some face masks. Now we all know that homemade face masks will not stop COVID-19 like the N-95 face masks that the hospitals desperately need, but they will help protect some and certainly can be used in other parts of the hospitals. I pulled out the fabric scraps from past quilts and ones my mother gave me. I did some research. I found this article and its links to be very helpful. I combined a few tutorials and had one of my nurse friends try them on so I knew which was best. I used two layers of good quality quilting cotton fabrics and a layer of either a good t-shirt or flannel. 

Sir Isaac Newton -- Father of Physics or Alchemist?

Disclosure: Candlewick Press gave me a copy of this book free of charge to review. All opinions in my review are my own and I did not receive any other compensation. As in all my reviews I am providing links for your ease, but receive no compensation.

Now I am sure you have heard of Sir Isaac Newton. He is considered the father of physics. You have probably heard the story of the apple falling from the tree and he discovers gravity. Well today's book tells the true story or at least as true as we currently know. The book is Isaac The Alchemist: Secrets of Isaac Newton Reveal'd by Mary Losure. 

Multicultural Math: Leonhard Euler -- Global Learning for Kids

This month Global Learning for Kids is exploring Switzerland. Since we explored Switzerland last year before Global Learning for Kids officially started, I thought we would focus on a Swiss mathematician. Hazel did remember some of the books and wants cheese fondue again. We did read a few of the same books and watched two DVDs (one of which we watched last year as well).

I Am Albert Einstein -- Ordinary People Change the World Blog Tour & Giveaway -- Multicultural Mathematics

Disclosure: Penguin Random House Books gave me a copy of this book free of charge for this review. All opinions in my review are my own and I did not receive any other compensation.  As in all my reviews I am providing links for your ease, but receive no compensation.

Today we are sharing the final book in the Ordinary People Change the World Series. We saved I Am Albert Einstein for last. Hazel absolutely loves this series and we have had a lot of fun sharing all eight books. At the end of this post there is a chance to win the entire series from Penguin Kids! We have shared I Am Abraham Lincoln, I Am Lucille Ball, I Am Martin Luther King, Jr., I Am Helen Keller, I Am Rosa Parks, I Am Amelia Earhart, and I Am Jackie Robinson.Brad Meltzer and Christopher Eliopoulos do an amazing job of making these eight people interesting and fun to children and show that each of us can change the world.

Today I am sharing a young adult book. It is about a high school boy, Seth, who is very good at math as well as video games. He wants to compete against the top Starfare players in the world and those are the professionals in Korea. What interested me was the idea of a multicultural math story. The book is In Real Life by Lawrence Tabak.

History of Zero:

Can you imagine a world without zero? Or perhaps you wonder why we need to represent nothing at all? For centuries there was no mark or symbol of zero. The history of the number zero begins in Asia. It is believed that the first people to have a symbol for zero were the Babylonians. The Babylonians had inherited the counting system of the Sumerians which was the first to have a symbol instead of hash marks for each number.

Happy Pi Day

Today is the official holiday of Pi Day!! As a former math teacher, I love to celebrate it. Last year I gave you some of the sheets I used with my high school classes to celebrate it and to justify our having pie. This year I thought I would look at a bit of the history of pi.
