Day 5 in the Mathematics Practice Intensive covered all things algebraic!
The biggest take away for me was the vocabulary. This also linked with something that someone said today and I thought about how often I talk about this with my colleagues too - "Lots of students can do the maths, they just don't understand the vocabulary. They don't understand what they are being asked to do in the question/maths problem" I can see the value in using TIP charts a lot more regularly in my programme and a lot more revising of vocabulary.
I also hadn't thought about the fact that all those symbols that we use daily in maths are actually crucial for algebra and also crucial for students to actually understand what they mean. For example the good old equals sign not just meaning that something equals something else but that two sides balance, they are the same.
