Students learn how to use function notation to transform graphs by a translation and stretch. As learning progresses they calculate composite and inverse functions. Finally, students are challenged to solve equations through interation and calculate a rate of change along a non-linear graph using differentiation.
Before progressing on to working with functions students should have a good understanding of solving quadratic equations and trigonometrical graphs. This is the final topic in the higher GCSE course as it takes place in Year 11 Term 3.
Earlier this week, my school took part in a trial OFSTED inspection as part of getting ready for the new inspection framework in September 2019. This involved three Lead Inspectors visiting our school over the course of two days. The first day involved a ‘deep dive’ by each of the Lead Inspectors into Mathematics, English […]
The method of how to solve quadratics by factorising is now part of the foundational knowledge students aiming for higher exam grades are expected to have. Here is an example of such a question. Solve x2 + 7x – 18 = 0 In my experience of teaching and marking exam papers students often struggle with […]
When learning how to write 3-part ratios students need to understand how ratios can be made equivalent. The start of the lesson reminds students by asking which of six ratios is the odd one out. This is presented to the class as they come into the lesson. Writing Equivalent Ratios A few students immediately go […]
