  1. “Doodling in Math class: stars “…… this video is about drawing stars by putting any numbers of Points and trying to connect these points together to get a star, and that the more points you put, the more different ways you can draw a star. And the way she did that was by drawing “p” points in a circle evenly spaced and then picking a number “ q” and starting at one point and go around the circle to connect the points until you get your star.

“Doodling in math class: Squiggle Inception” …. This video is about making squiggles out of squiggle until she filled out the whole page and it can be extended infinitely.

“Doodling in Math Class: Triangle Party”…. This video is about drawing triangles and that everything is made of triangle. The essence of two dimensionality, the three points that define a plane, they are just made up of triangles.

“Doodling in Math class Infinity elephants”…  This video is about drawing any shape you like and start filling it with circles all over until the whole shape if filled.

 

2. These videos are wonderful. The video ““Doodling in Math class Infinity elephants” was very interesting to watch.  I was totally confused watching this video because she talked really fast but ,  I was also so surprised of how can she make this great connection between her doodles and math. I was really inspired of how creative and smart she is . I learned a lot of things from watching this video, but one of the most important things that I learned is that math isn’t about memorizing formulas and following steps. we could be very creative in math by inventing new ideas that will make it more fun and more easy. the question that I have after watching the video is how did she come up with all these ideas because this was inspiring to me.

3. I think this video was inspiring to me. It had a great connection with math from the way she draws the shapes to filling them with circles. I think it is also very relevant to the work that I do in some of my classes. Sometimes when I do not understand something in any of my classes I start doodling by drawing flowers or hearts all over the page but I never thought that some of these drawing could have a connection to math. I also think there is a huge connection between Vi-Hart and Lockhart’s Lament because they both have the same ideas in different ways. Lament thinks math is not about memorizing and following formulas , it is about creating your own formula , which is the same idea as Vi- Hart, she created her own way of math by doodling .

The title of this video is “Hexaflexagons.” In this video Vi-hart talks about how a student named Arthur.H.Stone discovered and invented hexaflexagons with strips of papers. She cuts-off ends of the paper that could not fit in her English binder and then folds those strips of papers to create different shapes such as hexagons. Each time they were folded in a certain way it revealed more than two faces or sides creating a flexagon.

Title- “Doodling in Math: Sick Number Games” In this video Vi-hart she writes down numbers in order and arranges them in spirals known as ulam spiral to find out patterns prime numbers can make. She also doodles around to find patterns in pascals triangle by using this number game and highlighting prime numbers to create a picture with different sizes of triangles.

Title- “Doodling in Math: Stars” This is a great video to learn to draw many pointed stars in many different ways. She basically shows how factoring numbers are found in real world such as in stars.

Title- “Doodling in Math: Spirals, Fibonacci, and Being a Plant [1 of 3]”  This video is about how Fibonacci numbers are found in living things such as plants and other things. She practically experiments on plants to show how Fibonacci numbers exists in spirals and many other geometric drawings.

2. These videos are simply amazing! I am definitely inspired how Vi-hart makes great connections to math with her “doodle stuff” She was very creative in her drawings in the videos that made me wonder how artistic and yet clever enough to relate every single thing to math in some way. One thing I learnt is that she appreciated math more than I did and in some sense she made great attempts to prove the math facts herself by experimenting on real world materials instead of simply relying to the things she is taught in class. For example discovering the Fibonacci sequence in spirals of pine cones, pineapples, flowers and many others. And one question I like to know is if she came up with a math story every time she doodled in a math class?

3. I really enjoyed watching these videos. Vi-hart has a unique approach to math by making connections to real word applications. I also learnt a lot from “Spirals, Fibonacci and being a plant” video. I think the way she demonstrated on the flowers and other things to describe the Fibonacci numbers were very beneficial. And not only that she made math seem very unique and an enjoyable subject, and quite often math is not observed this way in a classroom because it’s mostly taught in a very boring way by spoon feeding facts to students where they don’t have the opportunity to be inspired with the mathematical concepts. I found this video also relevant to what is being taught in class especially with the Fibonacci numbers and its unique properties. She also shows how math is an art as described in the reading “Lock hart’s Lament” and uses her creative imaginations in her explorations. I honestly wish I was taught this way back in school.

Doodling in Math class snakes and graphs ( https://www.youtube.com/watch?v=heKK95DAKms&list=UUOGeU-1Fig3rrDjhm9Zs_wg)

This video was about doodling snakes and how it relates to graphs. Vi Hart showed us that when you draw and snake and you put the snakes head and the tail touching then you can create cool designs which deals with graphs.

9.999… reasons that .999…. = 1 (https://www.youtube.com/watch?v=TINfzxSnnIE&list=UUOGeU-1Fig3rrDjhm9Zs_wg&index=41)

This video was about how .999… = 1 is the same as saying 1/2 =0.5 because it has the same value. This reason is not a proof but it is to stay open minded where numbers that are different can have the same value. Vi Hart shows a equation in when you multiply by 10 and subtract x or .999… then divide by 9 you get .999….. She also shows us 9.999 rules of why .999….. equals 1.

How I feel about Logarithms (https://www.youtube.com/watch?v=N-7tcTIrers&index=8&list=UUOGeU-1Fig3rrDjhm9Zs_wg)

Vi Hart talks about how algebra is just fancy counting where you are only counting +1 +1 +1 +1. Hart states that numbers are just symbols of +1. She says that when you subtract or have negative numbers they are +1’s that is going back in time. She says division, multiplication, addition, and subtraction is only counting in a fancy way. To in log you use a system time count, where you have a system that counts in a time sort o way.

 

The video I watched more then 3 times was: Doodling in Math class snakes and graphs. When watching the video I was a bit confused because Vi Hart was talking way too fast and she kept drawing many different pictures. I liked her theories and what she believes in and I like that she was creative. Her creativity and her drawings made me more intrigued to watch more videos because it was interesting to see her perspective of certain math topics.  I really enjoyed watching this video because it made me think about the designs snakes can make which I have never thought about before, it made me more open minded. I learned that when you draw squiggles is the same as making snakes where the two sides are closed, where you can weave and put on the finishing touches, weaving works out perfectly. Where it works for any number closed curved on the plane. I learned that drawing integrals gives you a picture of a rope which is part of knot theory. I also learned that when you draw a squiggle and you close the squiggle up and you color every alternate part, there will be no two colors touching in your shape and this will always happen with any squiggle you draw which is pretty cool. You can also draw squiggle and make interesting surfaces when you shade them in where you will have one edge and one side. I wonder if there was other shapes or drawings that you can draw other then a snake that give you a function on a graph?

I believe that as a teacher I need to get students to be more open minded and not bored by teaching them just facts and formulas and what to memorize. I would have to come up with ways to get students to think creativity so that they are able to come up with ideas. I will guide them to do this. I believe that this is math because the drawings relates to graphs and how graphs are, but it deals with math in a creative way. I don’t believe its teaching I think its something a person can think about when they see a graph or when they are drawing. This wont be work I will be doing in a classroom however if I were to teach students about graphs I will mention this to them so that they can find it interesting and so that they can discover for themselves the way graphs behaves.  This relates to Lockhart’s theory when he stated that math is an art, because in fact I believe it is an art, and Vi Hart uses her creativity and art work to prove it. She uses her imagination of doodling in class which you cant get when you are given a formula to memorize. She is using her ideas in a creative way and it relates to math. Lockhart was right about how teachers don’t really let students use their own ideas or imagination because if we were able to do this we will be like Vi Hart just drawing an putting out ideas. that probably no one else has ever thought of.

1.a https://openlab.citytech.cuny.edu/2014-fall-mat-2071-reitz/?p=312#respond – “Doodling in Math class Infinity elephants”…  This video talked about a game you can play in almost any shape you decide to draw. You pretty much have to draw circles and circles until you fill up the entire shape inside.

b. https://www.youtube.com/watch?v=Gx5D09s5X6U&list=TLDmvTd50jxGk&index=10 – “How to snakes”….. In this video she talks about snakes and how they can be arranged in many different ways like in the game “SNAKE”. She represented the binary numbers by changing the colors of the snakeskin.

c. https://www.youtube.com/watch?v=jG7vhMMXagQ&index=6&list=TLDmvTd50jxGk “Pi is (still) Wrong” In this video she says how instead of PI we should use TAU. Its funny how she is baking a pie while describing PI

 

2. In this video I found it rather confusing. This lady talks so fast and in the video doodling in math class she draws a lot  of different animals and wierd shapes and talks about how doodling in math class is fun. I was a little confused because she jumps from talking about one thing to talking about another. One thing that I learned from the video was how she compared the “series” application into drawing elephants grabbing eachother’s tails infinetely. I found that very interesting. One question I still have is that if she can relate all of these videos to her own math life and how has it helped her?

3. What this video meant to me was inspiration. The way how she described doodling in math is a new form of way of looking at things from a different perspective. I know that sometimes I’ll begin doodling in my other classes like for example in “Number Theory” because I dont know whats going on in there. I will begin doodling about random things that dont relate to math in a sense, however I will keep track of each time I doodle and see how I can relate it to any math topic. This video wasnt really relevent to me in Prof. Rietz’s class.
