## Current Teaching

In the first semester of 2018/19 I am lecturing Elements of Number Theory in Leicester. Lecture notes, problem sheets and further resources will be on the course pages on blackboard.

## Previous teaching

### Cambridge Maths Tripos Groups Ia lecture course

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

### Video Solutions

Video solutions to some example sheet questions.

**You should only look at these once you've tried the question!** Some data will be saved when you watch the videos, such as where you pause, what answer you clicked, etc. You can use the tick boxes on the list of videos to indicated if you have "completed" a question; I will also be able to see this information.
