# Manipulating Sectors Formulae

Students learn how to manipulate the various formulae associated to the area of a sector and arc length to find the radius and angle theta.  As learning progresses they are challenged to solve more complex problems both with and without a calculator.
##### Differentiated Learning Objectives
• All students should be able to manipulate the formula for the arc length of a sector.
• Most students should be able to manipulate the formula for the arc length and area of sectors.
• Some students should be able to derive known facts for problems involving sectors through manipulating the formulae.

#### 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 […]
