Last summer I worked with my maths faculty to create our own tailored Mathematics Mastery scheme of work, for year 7 specifically. We looked at different scheme of work overviews, from different schools, and compiled our own. This year it has been really interesting delivering the teaching and learning of this project.

In this blog post I will share the interesting take I took in teaching my bottom Y7 set students the double connection between identifying the number of sides of each 2D regular shape, and identifying the name of a regular 2D shape by stating the number of sides of the shape in question.

I used a rhythm mnemonic which was inspired by a visit to Michaela Community School; as a technique used to embed factual knowledge in students’ long term memory.

So here it goes:

Triangle, Triangle, Triangle (Hold three fingers each time)

Square, (Hold four fingers)

Rectangle, (Draw a rectangle in the air using two hands)

Pentagon, (Hold five fingers on one hand like a star)

Hexagon, (Hold six fingers)

Octagon, (wave both arms like an octopus)

Nonagon, (Hold nine fingers)

Decagon, (Hold ten fingers)

And all the way around like a circle (Draw a circle using two hands) – The intention is to avoid the misconception that a circle has 0 sides when it has 1 curved side.
