Double Maths First Thing: Issue 5F

Double Maths First Thing is apparently abelian. Hello! My name is Colin and I am a mathematician on a mission to spread joy and delight in doing maths.

A fun project involving some of my favourite maths people: Tappy Mathematics, a project to develop and animate new maths songs for 3-6 year-olds. Warning: may give you unshakeable earworms. Some games to enjoy while those are going…
