MINDFUL MATHS - My aim is to share the videos I make for my students with the world to help with understanding and revision. The videos have been recorded in lessons and cover any misconceptions that come up live when teaching.
Edexcel International A-level Mathematics following the Pearson's student book.
Remember these lessons are to support and I do not recommend just using these, you also need to practice different styles of questions and complete past papers.
Mathematics is better learned in groups so you can improve your problem solving and reasoning skills. You got this!

RESOURCES - PowerPoint based on Dr Frost resources – Thank you. www.drfrostmaths.com

MISTAKES - I will put any corrections here if there are any – remember mistakes happen sometimes and if you have nothing nice to say then don’t comment, we are only human. 😊
