This is a whole lesson on cumulative frequency with resources and it does contain maybe my favourite ever presentation slide ( you will know which one! ) 15 slides + worksheet.
It comes with a starter, activities, very clear teaching, keywords, learning objectives, worksheet with answers and plenary. All there and ready to be taught. The next lesson is box plots, which builds on this lesson and is also available from my shop.
