What is atomization?

In this episode, Anna is joined by Craig Barton, former secondary maths teacher, host of the Mr. Barton Maths Podcast, author of How I Wish I’d Taught Maths, and a new Tips for Teachers book series. Craig reflects on how his teaching evolved after engaging deeply with learning science and educational research.

Together, they explore what effective explicit instruction looks like in math from atomisation and worked examples to checking for understanding, purposeful practice, and problem solving across the I do, we do, you do phases. This practical, research-informed episode is essential for educators looking to improve math outcomes by aligning instruction with how learning works.
