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.

Sharing an Amount to a Given Ratio

There are three common methods for sharing an amount to a given ratio.  Depending on the age group and ability range I am teaching I would choose one approach over the other two. The three methods are: Using fractions Unitary method Using a table In this blog I will demonstrate each of the three methods […]

Plotting Scatter Graphs and Understanding Correlation

To introduce plotting scatter graphs and understanding correlation I ask students to think about the relationships between different variables and to describe how they might be related. Here’s my starter activity which students discuss in pairs then present to me on mini-whiteboards. When the students have had time to discuss the matching pairs we talk […]

Plotting Quadratic Graphs on Cartesian Axes

In recent examiner reports it is noted how important it is for students to understand the properties of a parabola  when plotting quadratic graphs on Cartesian axes.  Students who have a secure understanding of parabolas can use them to correct miscalculated values in their table of results and are more likely to attain full marks […]
