## Current Teaching

I am teaching the first year module MA1114 Linear Algebra (year-long), and in the second semester MA1272 Plane Geometry. Students can find all resources on blackboard.

I have made a Gaussian Elimination Calculator and an Inverse Algorithm Calculator (using Numbas), where you can enter a linear system as an augmented matrix, resp. a square matrix, and then tell it which row operations you would like to do. The aim is to enable students to concentrate on which steps are required to get the matrix into reduced row echelon form, rather than the individual calculations per entry.

## Previous teaching

In Leicester I have previously taught Elements of Number Theory.

### Cambridge Maths Tripos Groups Ia lecture course

In Michaelmas 2016 I lectured the Cambridge first year course on Groups (for the third time). Here is the lecture-accompanying blog Think for yourself, on which I particularly wrote about how to think about and learn maths at university.

Further examples:

Examples of categories and functors
