This Cre8ate maths resource investigates the structure of some hydrocarbons. Molecules which have the same chemical formula but a different structure are called isomers. A printed sheet representing carbon and hydrogen atoms is cut up and used, as a kinaesthetic exercise, for students to build as many isomers as they can for two chemical formulae.

Students are then challenged to discover a 3-D shape with 60 vertices, made from regular pentagons and hexagons. Teachers may choose to give 12 pentagons and 20 hexagons to groups of students for them to build the model or make up the shape from its net.

Topics such as number patterns, simple algebra, reflection and rotation are included in this resource.
