Augmenting Math Class with Technology

Graphing

Once students become familiar with plotting points and graphing lines they can use their skills to notice patterns. However, plotting everything by hand can be a D-R-A-G on precious class time. At times we’ve used an online graphing calculator from Desmos to increase efficiency. These are some screenshots from our work:

Visualizing Geometry

Geogebra is a platform that has a number of applets for kids to explore. Students are developing a deeper conceptual understanding using the visuals these applets provide. Try exploring the connection between 3 dimensions and 2 dimensions using these applets:

Desmos Adds Suspense and Challenge

Desmos designs and curates a number of classroom activities that build suspense and add challenge. Marbleslides provides practice with equations in the y=mx+b format. Click on the student preview tabs to give the activity a try and see what you can recall about graphing lines.
