 The National Council of Teachers of Mathematics offers this website that is designed to help families enjoy math OUTSIDE OF SCHOOL through a series of fun and engaging, high-quality challenges that improve problem solving skills. The challenge activities that are designed with middle school math in mind, can be done online or downloaded in pdf files to print and use offline.

When you get to the site you will see animated characters and the words “Take A Challenge.” Click on those words and go directly to 4 math challenge problems that include: 

  • Line Up – How long would you have to wait if you were number 300?
  • Beating Heart – How fast does your heart beat?
  • Popcorn – Which shape holds the most?
  • Don’t Fall In – Why are most manhole covers round?

If you decide to take the challenge, notice that each time you click on a different math challenge, the menu bar at the top of the page will change allowing you to access hints and tips that will help solve the problem. If you like these challenges then go to the “Challenge Index” on the menu where you can access 80 challenge problems archived at the site.
 
Before you begin the challenges, you might want to take a moment or two to view the menu items on the home page. It includes information for teachers and for families in English and in Spanish along with a “Math Index.” The Math Index lists all of the challenges archived at the site by math topic such as algebra, geometry, measurement, numbers, statistics and probability – allowing you to more easily access the activities that relate to the strand of math you want to study.
 
Each of the challenge activities are designed to capture students’ attention with real-life problems making the math much more meaningful and thought-provoking. Families can have fun solving the challenge questions together. Bookmark this page, so you can return to the site and explore them all.

Maths Challenge

(mathschallenge.net/)

Age Range: 11-18 (Grades 5-12, with parental supervision)

 

This website offers a free archive containing hundreds of math problems and puzzles for a variety of skill levels.

When you get to the site you’ll see a horizontal menu near the top of the page. Click on “Problems” to access the archives. You can search by keyword for specific math strands such as algebra, geometry, trigonometry, calculus, etc.
 
You can also search by level of difficulty. The problems are ranked with stars and explained as follows: 

  • One Star – These problems require nothing more than a logical mind and a willingness to try things out on paper.
  • Two Stars – Problems begin to require insights and mathematical tools. For example, geometrical problems may require the use of simple trigonometry, number problems may require knowledge of factoring, etc.
  • Three Stars – A good knowledge of school mathematics and/or some aspects of proof will be required.
  • Four Stars – A comprehensive knowledge of school mathematics and advanced mathematical tools will be required.

Each word problem or puzzle comes with an illustrated solution, and often has suggestions for further exploration and learning.

Geometry “Eyeballing” Game

Geometry “Eyeballing” Game

(woodgears.ca/eyeball/index.html)

Age Range: 10 and up (Grades 5 and up, approximately; children with parental supervision)

 

Are you one of those people who needs to straighten slightly crooked pictures on the wall, when others aren’t even aware that something is just a little off square, off center, or not quite straight?


Then you’ll love this website that provides a free game that allows you to test your ability to determine if things are straight or crooked, while improving your spatial relativity and visual geometry skills.

When you get to the site you will see the game screen displayed. Click on “Help/About” below the screen, to get information on how the game works. You’ll have one chance in each of the following 7 categories to get the shapes as close as you can to their true form: 

  • Parallelogram
  • Midpoint of a Line Segment
  • Bisect an Angle
  • Center of a Triangle
  • Center of a Circle
  • Right Angle
  • Convergence Point of 3 Line Segments

Your speed and accuracy count. At the end of 21 questions you can see where you place among other site visitors who have played the “Eyeballing Game.” The game records your times and margin of error for each of your three tries.

This site is sponsored by an engineer who enjoys woodworking. You can see the rest of his site by clicking on the “Woodgears.ca” icon at the bottom of the game page. We have NOT reviewed that site, so parents, as always, should preview and supervise use.

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

 

This website is part of the massive MathForum.org and offers free lessons and activities to explore Pascal’s Triangle, a math resource known for patterns and applications in several areas of mathematics.

Named after seventeenth century mathematician, Blaise Pascal, the triangle’s properties made use of and further explored the already known array of binomial coefficients originally developed in Persia and China.  

When you get to the website you’ll see a menu divided into three sections by grade level: 

  • K-4
  • 5-8
  • 9-12

Click on “Lessons” to find an array of activities for elementary through advanced learners that include lessons, problems to solve, and printable worksheets.

Circle Math with Paper Plates!

Wholemovement – Folding Circles

(wholemovement.com/)

Age Range: All (All grades; children with parental supervision)

 

This is fascinating! Bradford Hansen-Smith has been folding circles and teaching people of all ages how to do it for twenty-five years. He states, “Mathematics is based on the geometry of drawing pictures of the circle and using parts of the circle for constructing information from these static images. The square and all other polygons are only a part of the circle, all limited to a specific number of sides. The circle has no sides, it does not have limits.”

Under “How to Fold Circles” you’ll find four free, fundamental activities with instructions to make: 

  • A Sphere
  • A Tetrahedron
  • An Octahedron
  • An Icosahedron

You’ll also find on the home page a fascinating animation that demonstrates how folded circles combine into a spherical pattern that Buckminster Fuller called the Vector Equilibrium.

Hansen-Smith was inspired by the work of Fuller, and now leads explorations into geometry and other forms of math by folding and joining circles. He claims that, “The circle is the most experiential, comprehensive, hands-on, educational tool we have… Every child in school should be folding as often as they draw pictures of circles, and discuss the information that is generated in the folding.”

Folding circles is accessible to anyone who can fold a circle in half, regardless of age or grade level. The main tool you’ll need are paper circles that are readily available in the form of paper plates.

By using the menu, you can read and discover more about folding circles along with information on Hansen-Smith’s workshops and products he sells in his online store.
