Nick’s Mathematical Puzzles

(www.qbyte.org/puzzles/)

Age Range: 11-18 (Grades 6-12, with parental supervision)

 

At this website you’ll find a collection of more than 150 math puzzles that cover algebra, geometry, probability, number theory, trigonometry, calculus, and logic. They have been selected “for the deceptive simplicity of their statement, or the elegance of their solution.” While they will challenge your cleverness, the site founder Nick Hobson (who has a math degree and works in computer software) says, they “usually only require pre-college math.”

When you get to the site you will see an introduction. Above it is a menu bar that provides access to 160 puzzles. View the “Index” to see the names of the puzzles archived here. Click on any one, and a new page opens with the puzzle. You’ll see 1-4 stars next to each puzzle title that designates the level of difficulty, with four being the most difficult.

As mentioned at the website, “Explaining how an answer is arrived at is more important than the answer itself. To this end, hints, answers, and fully worked solutions are provided, together with links to related mathematical topics. Further references are provided with many of the solutions. The puzzles are intended to be fun, with an educational element.”

Madras Mathematics

(madrasmaths.com/activities/games/games_home.html)

Age Range: 9-18 (Grades 4-12, with parental supervision)

 

This website offers instructions on how to play a variety of math games using materials you probably have around the house.

The games are challenging and fun. They require strategizing and critical thinking, while exercising math skills. They include: 

  • Board and Counter Games – You’ll find ideas for using game board grids, chess pieces, game markers or counters and other materials to play games that teach and reinforce math skills without seeming like math — which is great for the mathphobics in the house.
  • Coin Games – Use coins to learn about chance and probability.
  • Domino Games — Find an ingenious use of a chess board and a set of dominoes to play the game, “Domineering.”
  • Paper & Pencil Games — A variety of math games you can play with nothing more than a paper and pencil. Great for traveling in the car — or when waiting in line or at the dentist office.
  • Paper & Scissor Game — This one requires strategy and manual dexterity.

In addition to the games listed, you will find links to other webpages containing math games your students may enjoy.

When you get to the site, the math subjects under NROC Collection that can be selected from the menu at the left are: 

  • Arithmetic
  • Algebra & Geometry
  • Calculus & Advanced Math
  • Statistics & Probability

If you select “Algebra & Geometry” for example, you’ll see a list of presentations: Algebra 1, Beginning Algebra, Intermediate Algebra and Geometry. Choose one and a list of topics in each course will appear. Click on any one to see a 2-5 minute video explaining that topic. Use the arrow just below the video to move to the next topic, or choose whichever topic you want to view next from the list on the left of the video. (If you scroll all the way down the page, there are links to textbooks for Algebra 1, first and second semester that may help as you listen to those videos.)

These high-quality multimedia interactive lessons constitute a complete high school level course — all for FREE!  But there’s more! Other courses currently available are Biology, Chemistry, Economics, History & Government, and even Religion!

Bookmark this one. There is enough under any one of these subjects to keep a middle school, high school, or college student engaged and learning for a good long time.

  • Trig to the Point
  • Fun with Functions
  • Ordinary Differential Equations
  • And more.

Also, of particular interest to younger students might be “Math Magnifications”: short (about 5 to 30 pages each) enrichments, many of which were used as workshops given by Dr. deLaubenfels and Karen deLaubenfels to homeschooled children. Some of the topics are: 

  • Calculus
  • Probability
  • Statistics
  • Vectors

These “will give students a better picture of the breadth of math.”
