Belleville MicroSTEM 7-28: Applied Circuitry
Today, in MircoSTEM, the students examined real circuits in a calculator to see how a calculator functions and explore how numbers are displayed. Students focused on the display of the calculator, in particular how numbers are displayed using a 7-segment display.
Ask your student: What type of numerical display do most four function calculators have? (7-segment) What type of numerical display do most graphing calculators have? (Dot matrix)
