Maths Textbook (rather than revision/workbook)

[SplendidPendips]

My son is in Yr9 and needs to improve his Maths. He's started the AQA GCSE syllabus. We have a Maths workbook with questions to complete, in an attempt to help him at home (although he's despondent and doesn't engage). But what I really need is a textbook that explains HOW to do things. He gets set a lot of homework and when I try to help him find that I am having to constantly Google how to do something, learn it myself and then attempt to explain it to him. This takes a long time and he switches off even further. So, is there such thing as a textbook that talks you through how to do equations, angles etc etc for the AQA syllabus, rather than just a book with questions and answers??

There’s lots of maths teachers on YouTube who explain the theory in short videos.

an interactive web-based app may be more engaging than a book.
conquermaths is pretty good
there are others. eg. complete mathematics tutor.

The CGP books are brilliant. Corbett maths online too.

Would you say the book is more for you to help him than for him to use?
(I ask this because if it's for him, you might be better with online resources but if it's for you to support him, I can see why you'd like a text book).
Try looking at the major educational publishers websites. For example, OUP has a textbook, AQA GCSE Maths Higher Student Book: Oxford University Press
I can't vouch for how good this is personally but this is probably the kind of thing you want. Might be available cheaper somewhere secondhand.

Thank you, I'll check out the books and websites.

We can afford a tutor, but trying to find one is difficult!

CGP do a good text book - it will be on Amazon
