One of the most prevalent tools used in mathematics is the calculator. Furthermore the graphing calculator has become a staple in high school mathematics most likely starting with Algebra 2 or even lower classes.[br]This chapter in this GeoGebra book uses a popular online graphing calculator to help students get familiar with graphing.[br][br][url=https://www.geogebra.org/m/aytgty4f]https://www.geogebra.org/m/aytgty4f[br][/url]

Teaching geometry can have challenges, especially with students who may not be capable or have the affinity for art. Using technology would get over this hurdle by eliminating the need to draw figures, in addition to the frustration of not obtaining an accurate measurement because of poor drawing skills.

Functions pose challenges for most students because, unless they are well versed in physics, it is unclear what the actually applications are. Since the applications are not clear, developing a sense for what particular operations on a function does may be difficult. To develop this instinct this tool shows how certain operations transforms a function. [br][br][url=https://www.geogebra.org/m/xe4wxqbc]https://www.geogebra.org/m/xe4wxqbc[/url][br]

Spreadsheets are one of the most important tools in our modern world. In the real world there is often the need to record and compute large amounts of data. Using spreadsheets such as Microsoft excel is essential in businesses for keeping records and running analyses. Seeing how important this tool is in our society, students should have an introduction at an early age so that they are comfortable using spreadsheets .

Many students know how to solve problems, but lack understanding of why certain operations are necessary, or how they work. Using simple apps that explore concepts are a good way to explore without the need for an intensive focus on proofs with lower level mathematics students.
