Why GeoGebra?
GeoGebra is dynamic mathematics software for all levels of education that brings together geometry, algebra, spreadsheets, graphing, statistics and calculus in one easy-to-use package.
How to get started with GeoGebra.org​
Grade 7
Question: Construct a triangle ABC where AB = 6 cm, BC = 7 cm and CA = 8 cm
Challenge: How students construct a triangle without the value of angles?
Application: SMART Notebook or/and Geo Gebra
Grade 6
construct polygons using a variety of tools, given angle and side measurements (Sample problem: Use dynamic geometry software to construct trapezoids with a 45° angle and a side measuring 11 cm.)
Grade 7
​
demonstrate an understanding that enlarging or reducing two-dimensional shapes creates similar shapes;
Grade 8​
​
determine the Pythagorean relationship, through investigation using a variety of tools (e.g., dynamic geometry software; paper and scissors; geoboard) and strategies;
Grade 6
Question: Rotate letter M by an angle of 135° clockwise around point O (-1,1)
Challenge: How can I verify if my work is correct or not?
Application: Geo Gebra
Grade 6
Question: Rotate letter M by an angle of 135° clockwise around point O (-1,1)
Challenge: How can I verify if my work is correct or not?
Application: Geo Gebra
Grade 6
Question: Rotate letter M by an angle of 135° clockwise around point O (-1,1)
Challenge: How can I verify if my work is correct or not?
Application: Geo Gebra
Grade 5
Question: How to add or subtract proper fractions with unlike denominators
​
Challenge: Why do I need to find a common denominator using the L.C.M.
​
Application: Describing how to use one of GeoGebra's tools to add or subtract proper fractions.
Grade 5
​
Grade 4
Question: Compare the following fractions 2/5 and 2/9
​
Challenge: How 2/5 is greater than 2/9 (in general 5 is smaller than 9)?
​
Application: To compare fractions with like numerators, look at the denominators. The fraction with the smaller denominator is the larger fraction.

Grade 6
Question: How can we proof that the sum of the angles in a triangle is 180 degrees? What is the value of exterior angle
​
Challenge: Which online tool I can use?
​
Application: With Geo Gebra, it is easy to proof that the sum of the angles in a triangle is 180 degrees and to find the value of exterior angle
