Properties of Triangles

Students learn about the properties of triangles.  They explore the various unique triangles that can be made on a square and isometric grid.

To begin the lesson students recap the names of common 2D shapes.  In the development phase they are challenged to create siz unique triangles on a 3 by 3 grid.  The end of the lesson challenges them to consider why some properties in triangles are impossible.

Differentiated Learning Objectives

  • All students should be able to identify an isosceles, equilateral, right-angle and scalene triangle.
  • Most students should be able to know the properties of different types of triangles.
  • Some students should be able to create all the unique triangles on a 4 by 4 grid.

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 […]
