*actual learning* books not revison Qs Edexcel higher maths

[DamsonInGin]

I am clueless.

DS Y10 has missed out on some of the curricula for Covid and house moving reasons.

He is doing Edexcel higher maths curriculum. He has logins for Mathswatch and now Dr Frost Maths. He's missed - for one example - the trigonometry lesson - and hasn't done that homework. I tried to help him and we watched the videos, but that isn't enough.

I am struggling to find a book or something online I can order with the actual curriculum in it - not just 'revision' or questions and answers. He needs the actual nitty-gritty on-the-blackboard explainer to crack the understanding of trigonometry. Everything is assuming you've already had the lesson!

I myself understood trigonometry enough to get a B at maths for about two weeks in 1990 and it's vanished!

Corbett Maths is a brilliant website that has an explanation video for every topic along with textbook q&a and exam practise. Examsolutions.net has a video explaining every question so although it's not exactly a lesson it goes through each step of the solution. If you want a book to edexcely you need to be looking for a Pearson textbook. They usually have worked examples. There are also loads of videos on YouTube with explanations of topics, it's just a matter of searching the right thing! GCSE trig introduction would probably be a good starting place.

Does he have the CGP guide?
It does assume you've a clue but it isn't questions.
It covers in revision guide format the whole curriculum.
CGP also do a white book of practice questions, not just 'exam style' ones, but things to build knowledge.

Trig. basically the ratio of the length of sides of a right angled triangle links to the angle.
Those ratios are called sine cosine and tan.
So if you know 1 side and the angle you can find the other sides, or if you know 2 sides you can find the angles.
It isn't as complicated as people make it out to be once you get there.

Thanks! It's good to look at a few different versions of these things - no chance of that when I was doing this. I'm struggling to balance just letting him do it himself and not being satisfied because I haven't grasped it 100%.

He has form for pretending to do stuff as he has ADHD and is super clever at non verbal reasoning and average at actually writing stuff down in a way he can be assessed - classic ' spiky profile'. He likes to learn his way or the highway

We found DS had some maths gaps over Christmas. He has done this before, forgets earlier principles after moving on, so needed back to basics coverage of things he swore blind he'd never seen before but I remembered him doing in year 9. Anyhow, Maths Made Easy website was brilliant. Don't need to sign up and it breaks down every element of curriculum with supporting examples and exam style questions.

Have a look at the Oak National Academy. They are actual lessons.

Oak National are good resources.

In terms of curriculum, you would need to go on the Edexcel website for the specification document. That outlines all the content required for the GCSE. Maths isn't my area and I would imagine most of the specifications are fairly similar.

Most courses have some sort of official guide, at least I've found that for my subjects.

This is my current favourite textbook www.amazon.co.uk/IGCSE%C2%AE-Textbook-Higher-Course-Revision/dp/1782944370/?tag=mumsnetforu03-21 but you need to be careful to check against the syllabus as some topics are igcse only.

Definitely combine it with some of the video resources recommended by pp.

Khan academy have videos that teach everything really well. For science and maths. My DC have watched a few. I have seen a few with them and I understood the maths!

Great resources much appreciated all.
Thank you
