# Angles in a Triangle

Students begin by investigating the sum of the angles in different types of triangles.

As learning progresses they apply the sum of angles in a triangle and other geometrical properties to solve more challenging and complex problems.

##### Differentiated Learning Objectives
• All students should be able to calculate the remaining angle in a scalene and right angled triangle when given the two.
• Most students should be able to use the properties of triangles to calculate angles in isosceles and equilateral triangles when given one.
• Some students should be able to calculate angles in compound shapes involving multiple types of triangle.

#### 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 […]
