In this triangles lesson, we’ll discuss the three different types of triangles. There are equilateral triangles, isosceles triangles, and right triangles.

Do you know what it is to be an isosceles, right, and equilateral triangle?

Your challenge is to build one isosceles triangle, one right triangle, and one equilateral triangle.

Your child should find that it is not possible to build an equilateral triangle. At this point is a good time to figure out why. See if they can figure out how many degrees should be in each equilateral triangle. Ask them to find two different ways to prove that it is impossible to build equilateral triangle other than just having attempted to do so.

Proof one: there are 180° in a triangle. 180° divided by three angles of a triangle equals 60° per angle. There are 360° in a circle. The circular ball has eight different holes. 360÷8 = 45.  Because the angles and available are 45 and greater than or equal to 90 it is impossible to build a 60° angle and therefore you cannot build an equilateral triangle.

Proof two: we know that two of the points on the ball are 90° apart 90÷2 = 45. And equilateral triangle is made up of 60° in each angle totaling 180 degrees.  60° is not equal to 0°, 45°, or 90° and therefore you cannot build an equilateral triangle.

Joe Donahue is the manager of day-to-day operations and the person who originally conceived of the TOOBEEZ product.

Joe had a vision to create a life-sized Tinker Toy(TM) for families to play with to help reconnect with each other. It took four years of business planning, market research, manufacturing trips, endless conference calls with engineers, designers and patent attorneys but finally on September 21, 2003, the Toobeez product was born!

Often referred to as Giant Tinkertoys(TM), Toobeez is a life-sized construction building system comprised of interlocking tubes and spheres that can be linked together to create anything imaginable, from a simple cube shape to a complex structure like a lemonade stand, house, airplane or submarine. Just connect, twist and create!

Initially, Toobeez was sold exclusively to the specialty toy market, but due to its open-ended nature, it didn’t take long to realize the versatility of the product and the many different ways it could be used.

Today, the Toobeez system is currently being used by educators, team building/training professionals, occupational and recreational therapists, camp counselors, Boy and Girl Scout troops, church youth groups and the list grows every day. There is even a group of forward thinking dog trainers who use Toobeez to create challenging courses for agility training (we're not making this up)!

Armed with the knowledge that there was more to Toobeez than just a toy, Joe reached out to industry experts and educators with the goal of developing a collection of materials that provide activities, educational tools and lesson plans for use with Toobeez. Among the topics covered: team building, math, language arts, occupational therapy and special needs and senior needs. Currently under development is a corporate team building workbook and a physical education activity book.

Whether in a playroom, classroom, corporation, camp or healthcare setting, Toobeez aims to provide every participant with a positive, healthy and fun learning experience!

Since the inception of Toobeez in 2001, it has been the company’s mission to connect people, inspire creativity and foster imagination. As a testament to their roots, Joe and the entire Toobeez team continuously strive to deliver a quality product that promotes connection and teamwork to ultimately bring people together.
