Using a compass and straight edge, we find the four traditional centres of a triangle : i.e. the incentre, the circumcentre, the orthocentre and the centroid. We also look at the Medial Triangle, and the Euler Line. The Centre of a Triangle (Compass and Straight Edge) PowerPoint Lesson: Compass and Straight Edge – The […]
In this lesson, Teacher Jon examines the famous Monty Hall problem in Probability by using a tree diagram……. Includes some footage of Monty Hall. Video Lesson: Download Worksheet (PDF): PROBABILITY – The Monty Hall Problem for Students
In this video we look at Pythagoras Theorem using Geoboards with teacher Jon. Video Lesson: Download Worksheet (PDF): MWG Pythagoras Theorem Wkst_1

In this video, Teacher Jon introduces the Fibonacci sequence using the question posed by Fibonacci in 1202, and continues with some applications of these numbers , in architecture, art, design and nature. Video Lesson: Download Worksheet (PDF): NUMBER THEORY – Fibonacci Numbers
In this lesson, Teacher Jon explains Factors and Multiples, as well as the Highest Common Factors and Lowest Common Multiples. Video Lesson: Download Worksheet (PDF): NUMBER THEORY- Factors and Multiples.
In this lesson, Teacher Jon provides some easy angle problems, for Lower Secondary Maths students, but a basic knowledge of the terms and symbols used in Angles is still required– (for instance, see my video on Angles – Introductory Terms) .

In this video, Teacher Jon shows 7 algebraic proofs of Pythagoras Theorem, using a geo-board and a worksheet. Video Lesson: Download Worksheet (PDF): Pythagoras Theorem- Algebraic Proofs_3
In this video, Teacher Jon describes 4 geometric proofs of Pythagoras’ Theorem (including Euclid’s) both on a worksheet, and on a geoboard. Video Lesson: Download Worksheet (PDF): Pythagoras Theorem – Geometric Proofs_3
Teacher Jon shows how geoboards are one of the best hands on tools for learning Maths, by demonstrating the range of topics at the Lower Secondary Level that geoboards can be used for, giving over 100 examples based on a standard curriculum. When given live, this talk is always followed a workshop where students are given […]
In this lesson, Teacher Jon explains how to make a class set of 30 geoboards, cheaply and easily. Students can help in this process, which increases their interest. Geoboards are hardy, and last many years if stored correctly. They are very useful in teaching Maths from Primary up to Lower Secondary , i.e. up […]
