Teaching with GeoGebra

Educational technology like GeoGebra can only facilitate understanding if the students themselves use it. This page contains a list of my post that describes activities and teaching sequence that I think might help to train students in using GeoGebra as a tool in learning mathematics. I have also included in this list lessons with GeoGebra applets.

Introductions:

1. Teaching with technology – why technological pedagogical content knowledge is a necessary condition for teaching mathematics effectively
2. GeoGebra and Mathematics – includes introduction to GeoGebra
3. GeoGebra, Calculators, and Mathematics – why teach with GeoGebra
4. Teaching Mathematics with GeoGebra

Integrating learning of GeoGebra in the learning of mathematics:

1. Investigating Coordinates of Points – learning the point tool and coordinates of points
2. Squares and Square Roots -  polygon tools and surds.
3. Adding radicals – regular polygon tool and text tool and geometric representation of sum of two radicals.
4. Investigating the graphs of the sum and difference of linear equations – an introductory lesson for solving systems of linear equation by elimination method.

1. Locus from two perpendicular lines
2. Perpendicular segments
3. Problem solving about ratio of areas
4. What is a coordinates system?

Other Applets used in teaching and learning

1. Quadrilaterals – my post on problems involving quadrilaterals. I created an applet on how to construct a quadrilateral equal in area to a given quadrilateral.
2. Making connections through math investigation – includes a GeoGebra applet on preserving area of triangles.
3. Introducing the concept of function – includes a GeoGebra applet for identifying changing and unchanging quantities and determining the relationship between two varying quantities.
4. Angles made by transversal – contrasts two applets, pros and cons for teaching angles made by transversal.
5. Constructing polygons with equal area – a problem solving lesson applying the concept of area and parallel lines
6. Square of a sum
7. How to scaffold problem solving in Geometry
8. Christmas GeoGebra Applet
