These three points, when joined together will form into an equilateral triangle. The equilateral triangle will be used as a template to make a tetrahedron.

These simple calculators are a good example of calculators we used in my classroom. Each student was required to have and organize their calculator.

Calculators helped me teach math operations. A calculator promotes thinking and reasoning skills when solving problems.

When students were reading a novel in the class as a group or individually they were required to have their calculator beside them. At any time, I could ask them the fraction, decimal equivalent or percentage of progress they were making toward completing their novel.

My students used a calculator for a variety of other mathematical purposes. The calculator, circle protractor and pencil compass made solving geometry problems an enjoyable experience.
