# 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.

#### How to Draw a Venn Diagram to Calculate Probabilities

There are three common ways to organise data that fall into multiple sets: two-way tables, frequency diagrams and Venn diagrams.  Having blogged about frequency diagrams before I thought I would write about how to draw a Venn Diagram to calculate probabilities. Recapping Two-Way Tables This activity works well to review two-way tables from the previous […]

#### Calculations with Percentages

Students learn how to find a percentage of an amount using calculator and non-calculator methods.  As learning progresses they use decimal multipliers to find a percentage change and calculate a simple interest in financial mathematics. This topic follows on from Fractions, Decimals and Percentages and takes place in Year 8 Term 5. Calculations with Percentages […]

#### Proving Geometrical Relationships using Algebra

Back in May 2017 maths teachers around the country eagerly awaited the first exam for the new GCSE Mathematics syllabus.  Proving geometrical relationships using algebra featured at grade 9.  In Paper 1 of Edexcel’s test paper the last question of the higher tier looked like this. Edexcel wrote about student’s performance on this question in […]
