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

When students were reading 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 book.

My students used a calculator for a variety of other mathematical purposes. The calculator made solving math problems an enjoyable experience.
