Math is the most common subject that students fear in the classroom and those who fear it more, are the teachers. With a tool like GeoGebra, it provides explanations and questions that can be utilized within the classroom to help simplify all the complexities and fears that come with math.
For instance, the image below depicts a lesson going over the area of a triangle which has a formula of Base x Height divided by 2 ((b x h)/2). But as an elementary school student learning this lesson for the first time, I was quite confused as to why this equation was the rule to finding the area of a triangle. Later on in life, it was explained to me that if you take a right-angle triangle, for example, copy said triangle and line it up along the hypotenuse, it will create a square or rectangle which has a formula of Length x Width (l x w) or rather Base x Height (b x h). This, in turn, relates back to and explains the formula for finding the area of a triangle.
This theorem can also be used in explaining how to find the area of a parallelogram, trapezoid, rectangle, rhombus, or any other quadrilateral shape. With GeoGebra, there are many tools at one's disposal and it makes it super easy for teachers to find appropriate resources for their own classrooms.
