Create Interactive Materials - Dynamic Equations Dynamic Equations ● Create two sliders named a and b ○ settings: Number, Min: -5, Max: 5, Increment: 0.1 ● In the "Input," type y = a*x + b ● Move the sliders, and notice how the graphics view changes Create Interactive Materials - Dynamic Shapes Dynamic Shapes ● Create two sliders named n ○ settings: Integer, Min: 3, Max: 10, Increment: 1 ● In polygon menu, select "Regular Polygon" ○ Make two points in the Graphics View ○ Put "n" into vertices pop-up ● Move the sliders, and notice how the graphics view changes Create Interactive Materials - Spreadsheet Dynamic Spreadsheets ● In Input, write equation f(x) = x^2 + 2*x + 1 ● In the menu, select "View" and check "Spreadsheet" ○ In column A, list number -5 to 5 ○ In column B, type f(A1) ○ Select cell B1 and drag down to B11 Create Interactive Materials - Spreadsheet cont. Dynamic Spreadsheets Works only on Downloaded program ● Select cells A1 to B11 ● Right click (on Mac Ctrl+click) selected area ○ Select Create -> List of points ○ Notice the points created in graphics view ● In the input, change f(x) to f(x) = x^3 - 8 and notice how the graph/points change Create Interactive Materials - Spreadsheet cont. Dynamic Spreadsheets Works only on Downloaded program ● Select cells A1 to B11 ● Select "One Variable Analysis" from top menu ● One-variable distribution, like a histogram, is created GeoGebra in the Classroom ● Example Assignments Using ● Example Student Projects Using GeoGebra GeoGebra ○ Exploring Vertical Angles: ○ https://www.geogebra.org/m/ZMTWGXuu http://www.tinyurl.com/GeoGebravertical ○ https://youtu.be/BjUrTSW6jNc ○ Exploring Equations of ○ https://youtu.be/i5jN50avxoE Parallel/Perpendicular Lines: ○ https://youtu.be/ngrz5-D3_LU http://www.tinyurl.com/GeoGebraparperp ○ https://youtu.be/KS-EF65VrWM Download/Edit from GeoGebra Tube ● Find a simple applet you like in ● Open the file you downloaded on GeoGebra Tube the computer ● Think about what you might ● Select View -> Construction edit/add Protocol ● Press three dots in the top right ○ This allows you to see how the applet corner was created ● Select "Download" ● Edit features you would like to ● Download the .ggb file change Useful Links ● Online manual: http://wiki.geogebra.org ● GeoGebra website: https://www.geogebra.org/ ● GeoGebra twitter: https://twitter.com/geogebra ● GeoGebra Groups: https://www.geogebra.org/b/r Qrbooeq#chapter/59731 ● Contact me: [email protected] Session Time: 10:00-10:50AM Session Title: Using GeoGebra to Enhance Mathematics Instruction.
