A series of lessons were designed to help Secondary 3-4 students visualize the angles formed (i) between lines, (ii) between a line and a plane, and (iii) between planes, which were found to be difficult to learn among secondary mathematics learners. These lessons incorporated both 3D printed models by a 3D printer, as well as students’ hand-drawn “lines” using a 3D Printing Pens (see figures below).

That is cool! students can see the cross sections as well! I love this design! Making mathematics visible
Not only visible, but also touchable. I believe this kind of teaching method which make mathematics live can benefit students a lot!!
