# Instantaneous Rates of Change

Students learn how to calculate and interpret instantaneous rates of change in different contexts.  By drawing a tangent at a point on a curve students find the gradient as an instantaneous rate of change.
##### Differentiated Learning Objectives
• All students should be able to find the equation of a line that is tangential to a curve at integer values of x
• Most students should be able to find the equation of a line that is tangential to a curve.
• Some students should be able to use variation to model a non-linear function and calculate an instantaneous rate of change.

#### Angles in Polygons

There are two key learning points when solving problems with angles in polygons.  The first is to understand why all the exterior angles of a polygon have a sum of 360°.  The second is to understand the interior and exterior angles appear on the same straight line. Students can be told these two facts and […]

#### Mathematics OFSTED Inspection – The Deep Dive

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 […]
