Learning to draw the line segment bisector and the angle bisector

Our 1st grade students are learning how to use the compass and the ruler to draw a line segment bisector and the angle’s bisector.

Once they have learned how to do it, they practice by building and designing fans!

Here you have some links with animations to remember the steps you must follow to draw these technical drawing constructions:

Here are also some examples of the drawing teacher’s blackboard to explain the fan design exercise:

Later, we will upload here some of the best designs of the students.
