#### Calculator.net: A Handy Website for the Math Classroom

**Summary : ** Helping You Calculate Online!

Calculator.net provides online calculators for a variety of purposes. From the website’s main page, users can click the “Math” option and choose the type of calculator they want to access. In addition to the calculators for Statistics and Geometry, users can access calculators for factions, time, square roots, mass, and many more. Once users select a calculator, they must input the required data and then click the “Calculate” button. The website will then process the data and provide users with the information. In addition, this website provides the formulas, equations, and raw data used to make the calculations.

### Instructional Ideas

- Teachers can present students a word problem. Next, teachers can have students select the calculator needed to solve the word problem. At this point, teachers can either let students solve the word problem using the calculator or have students solve the word problem without the calculator (afterwards, students can check their work using the calculator).
- After students have completed a problem, they can use the calculators in this website to check their work.
- Teachers can let students explore the different calculators included in this website. Next, teachers can have students write examples for when the different calculators would be used. Students can then share their examples by posting them to a class website.
