This term, Year 8/9’s have started Main Lesson on the topic of Platonic Solids.

These are unique shapes discovered in antiquity that were then thought to be the building blocks of life and the universe, defining all manner of things, including planetary orbits. These days, our understanding has deepened through molecules, atoms, and sub-particles, laws of gravity, orbits, and quantum theory. Students are investigating the historical context and mathematical properties of these shapes. Minds are stretched by drawing accurate models using just a compass and ruler, old and new techniques. They can also indulge their creative and childlike selves, building and colouring models, attempting to be as precise as possible. This topic provides a great opportunity to introduce more complex geometry and touch on the basics of trigonometry. Year 9 math practice lesson ties in neatly as they are learning to understand 3D manipulations, drawing projections of these same objects whilst continuing algebraic exercises. It’s been lovely to be in the classroom as a new teacher, I hope to bring them learning in interesting and practical ways.

A quiz for you: what errors are in my hand-drawn blackboard image attached (your child knows)?
