I've been writing this blog for two months now and haven't yet figured out exactly what I want to do with it. In my previous post, Resources Anonymous, I admitted I have a serious resource addiction. Based on the popularity of that post, I think I might make this blog primarily a resource library. So you can come here to look for resources and ideas when you're planning lessons. Would that be helpful? I like to be helpful. I suppose that's why I became a teacher.

Today I'm focusing on complex numbers. Although not widely studied in UK secondary schools (only by Further Maths students), there's certainly no shortage of teaching resources online - here's some highlights:

- First, my top find - Complex Number Operations Teaching & Learning Plans from the Project Maths Development Team. This is packed full of lesson ideas and there are tonnes of brilliant student activities in the appendices. I'm excited to start using these. There's also a PowerPoint version.
- I highly recommend the activities provided by the Further Maths Support Network/MEI (school login required). Here's an example of their topic notes. Their range of resources also includes worksheets, activities and assessments.
- SRWhitehouse on TES produces excellent A level resources, including a selection on complex numbers. I particularly like this introductory exercise.
- Illustrative Mathematics gives us seven excellent activities:
- Computations with Complex Numbers
- Complex Number Patterns
- Powers of a Complex Number
- Complex Square Roots
- Complex Cube and Fourth Roots of One
- Complex Distance
- Completing the Square
- As mentioned in my earlier post on Venn activities, this resource sheet is about classifying types of numbers. There's a related activity on page 32 of Complex Number Operations Teaching & Learning Plans.
