Surface Area of a Cone

Students learn how to calculate the curved surface area of a cone and total surface area of a cone by considering the net shape of a sector and circle.  As learning progress they calculate the are of complex composite shapes involving cones.
Differentiated Learning Objectives
  • All students should be able to calculate the curved surface area of a cone using the formula.
  • Most students should be able to calculate the total surface area of a cone using Pythagoras’ Theorem to calculate the slant.
  • Some students should be able to manipulate the formula for the area of a cone to calculate the radius, slant or perpendicular height.

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 […]

How to Solve Quadratics by Factorising

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 […]

How Write 3 Part Ratios

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 […]
