I know break even can be a tricky topic for students to grasp at first, this 4 lesson pack is all you'll need to teach break even in depth!
There are 4 lessons in here, more than what you will probably cover for break even, but there are a range of practise activities, new style exam questions etc to develop understanding of break even.
This is best for the new Edexcel GCSE but can definitely be used for the old unit 3 or to be honest, any exam board or spec - to teach break even in a fun and challenging way.
It is in a zip file with worksheets etc. the cover image shows a few slides.
Thanks and enjoy!
