Dimensions

(www.dimensions-math.org/Dim_E.htm)

Age Range: 12-18 (Grades 7-12, with parental supervision)

 

Created by three math enthusiasts (with terrific credentials) this site offers a free film on mathematics that references the work of renown mathematicians, scientists, artists, and others in a multi-media presentation that is sure to amaze and (hopefully) make the subject matter understandable.

When you get to the site, click on “Tour/Guide” to get an overview of the course. Then click on “Watch Online” and choose “American English” to start the video in English. Of course, if you prefer, you can watch it in German, French, Spanish, Italian, Japanese, Russian and Arabic.  

Back on the main page, click on “Details” so you can follow along by chapter: 

  • Chapter 1, Dimension Two – Learn or review what meridians and parallels are.
  • Chapter 2, Dimension Three – Mixes “elementary” math with imagination and philosophical elements.
  • Chapters 3 and 4, Fourth Dimension – Contains more difficult mathematical concepts. However, the viewer is encouraged to pause the film and consult a reference page for additional information. As the creators explain, “you can always sit back and enjoy the pictures!”
  • Chapters 5 and 6 – Contains an introduction to complex numbers that could also be used as a refresher course. As the designers explain, “If you know nothing about complex numbers, you should push the pause button as often as you like, and try to understand using the references that we propose. These chapters are the most ‘school-like’ of the film. To thank you for your efforts, chapter 6 ends with an amazing deep zoom scene.”
  • Chapters 7 and 8 – Get an introduction to the Hopf fibration. Again the film creators explain that even though it’s not beginner’s stuff, “it is quite pretty and deserves to be understood.”
  • Chapter 9 – Shows the proof of a theorem of geometry that is relatively “elementary.” As the designers explain, “Without proofs for theorems mathematics would not exist, and we wanted to make this very clear at the end of a film that is essentially about mathematical objects.”

Each lesson or “chapter” of the film is almost 14 minutes long. Watch it in segments or sit down and watch the whole thing in one sitting. You are encouraged to use it in a way that works for you “based on your interest, your prior knowledge on the subject, or simply on your mood of the moment!”

Simpsons Math Activities

(mathsci2.appstate.edu/~sjg/simpsonsmath/)

Age Range: 10 and up (Grades 5 and up approximately; parents should preview and supervise)

 

In many episodes of the popular animated sitcom, The Simpsons, there are references to mathematics including arithmetic, geometry, and calculus that uncover and poke fun of mathematical illiteracy. As explained at the website, “Al Jean, Executive Producer and head writer, has a bachelor’s degree in mathematics from Harvard University.”

Two math professors saw the potential to use math references in The Simpsons as an “ideal source of fun ways to introduce important concepts to students, and to reduce math anxiety and motivate students…”

When you get to the site, you’ll see a brief introduction, followed by a menu that includes: 

  • Mathematics on The Simpsons – Read a few articles that reveal where and how math is used in various episodes.
  • Engaging Students with Related Mathematics – Get free “Activity Sheets” based on math references in random episodes of The Simpsons. They are designed for classroom use (but can be tweaked for homeschooling) and cover concepts such as: 
    • The Pythagorean Theorem
    • Arithmetic and Number Theory
    • Pre-Calculus and Calculus
    • Probability

You’ll also find links to media coverage in which the writers and other crew members talk about the math and science in The Simpsons‘ episodes. And there are suggestions and cautions for teachers about using pop culture in the curriculum as well.

BONUS! Mathematics on Futurama! That’s right, the science fiction cartoon series has math and science references in almost every episode. One of the comedy writers on Futurama! has a Ph.D. in applied mathematics from Harvard and you can read about his “inside jokes” in various episodes. The site is similar to The Simpsons math site, and contains free Futurama! math worksheets.

Note: While these programs may be pop culture icons, some contain controversial subject matter. As always, parents must preview the material and supervise Internet access.

This site offers an array of resources including animations, science, and Incan history in order to help students learn Euclidean geometry.

The Incas were a civilization in western South America near Cuzco, Peru. You may have heard of Machu Picchu, an ancient fortress city of the Incas in the Andes Mountains. The Incas were superb craftsmen and architect-engineers. Nazca Lines are geoglyphs (drawings on the ground) that are believed to have been created by The Incas during the 15th and 16th centuries. There are about 300 figures – among them are geometric shapes. 

When you get to the website you’ll find geometry problems with step-by-step solutions, proofs, colorful animations, quizzes, puzzles, quotations, and more. Click on the featured ilustration that interests you or scroll down the page to find the “Table of Content” for more. 

There is lots of content here – so much, in fact, that we weren’t able to review it all. Therefore, as always, parents should preview the site to determine suitability for your own children.

A+ Math Games

(www.aplusmath.com/games/index.html)

Age Range: 5-18 (Grades K-12, with parental supervision)

 

This website contains fun, interactive games for learning basic math facts in addition, subtraction, multiplication, division and geometry.

The games include: 

  • Matho – This is math and bingo combined for “Matho”! Includes game board and games for addition, multiplication and division facts. When you get to the web page, you will see a game board with numbers on it. Below it are questions like “What is 8 x 5?” You do the math, and get the answer – in this case “40”. Then you click on the number 40 on the game board. As soon as you get 5 in a row – you have Matho!
  • Hidden Picture – Choose your subject to get to the game board with numbers on it. Above the game board are math fact problems like “8 – 3?” You find the correct answer on the game board and click on it. If you are correct a piece of the hidden picture is revealed. Once you answer all of the questions correctly – you get to see the whole picture!
  • Math Memory – Click on the type of Math Memory game you’d like to play. On the next screen, you will see 2 game boards. Both boards are covered in question marks. Click on a square on one board, and you will see a math fact like “3 + 3?” Then you click on a square on the other side to try to find the solution. The idea is to try to remember as you click from one side to the next what facts and answers lie beneath each square. Requires concentration and develops good memory skills. Once you clear both boards by finding the solution to each math fact, you win!

These games are a great way to remedy the boredom of drill and practice with basic math facts.

When you finish the games, check out the rest of the site to find flashcards and worksheets and homework help. Highly recommended!
