Misconceptions are very different from the mistakes students make. Mistakes are not consciously made. Misconceptions are. Mistakes are usually one-off, while misconceptions, the gods forbid, could be for keeps. Mistakes are
Geometric relations – angles made by transversal
Geometry is a natural area of mathematics for which students should develop reasoning and justification skills and their appreciation of the logico-deductive part of mathematics that build across the grades.
Problem on proving perpendicular segments
This problem is a model created to solve the problem posed in the lesson Collapsible. In the figure CF = FB = FE. If C is moved along CB, describe the paths
Geometry lesson: Collapsible chair model
We live in a 3-dimensional world but why is it that we start teaching geometry we start from 2-dimensions to 3-dimensions? Shouldn’t it the other way around? Aren’t we supposed
