Video: Finding Equivalent Fractions and Simplifying Fractions
Fractions: This video will explain finding equivalent fractions and simplifying fractions. We also explain what a fraction is. Practice questions are provided at the end of the video.
Video: Types of Angles
This video will explain the different types of angles in math. We explain acute angles, right angles, straight angles, obtuse angles, reflex angles and full rotations. Two sets of practice questions are at the end of the video for students to test their knowledge.
Name The Parts Of A Circle | Geometry Video
This video is a link to an animated video covering how to name the parts of a circle such as the arc, segment and chord. Practice questions are at the end of the video asking students to match descriptions to the names, followed by labelling the parts of a circle.
Why Do We Use Letters In Algebra
This is a gentle introduction to algebra and is a great activity to introduce the concept of using letters to represent unknown values. To demonstrate this we use shapes in place of letters and ask learners to find the missing number. Practice questions are provided at the end of the video.
Video: What Is A Surd | Understanding Surds
This is a link to an animated video explaining what a surd is. This video can be used as part of a wider lesson on surds. Understanding exactly what a surd is, is crucial to learn before moving onto manipulating/simplifying surds.
Video: Simplifying Surds: Multiplication
This video explains what simplifying a surd means and how to simplify surds by multiplication. The three multiplication rules are explained with examples. Practice question at the end of the video.
Angles in Parallel Lines
This is a link to our YouTube video which explains the rules for an angle formed by a transversal (line) crossing a pair of parallel lines: corresponding angles, alternate angles, corresponding angles and allied angles. Practice questions are at the end of the video.
Bearings in Maths
Link to YouTube video: This video will explain what bearings are in maths and how to calculate them. A practice question is provided at the end of the video.

02:29 Example two: finding a bearing when given another bearing
03:34 Example three: finding a point when given two bearings
04:33 Practice question and answer
Probability Tree Diagrams
Link to YouTube Video: This video explains how to work with tree diagrams for probability. We explain how to use them to calculate probabilities for a combination of outcomes for more than one event and how to draw a tree diagram for a probability question.
Visual Algebra: Rods
Visual Algebra Series Video One: This video explores a different way to think about and visualise algebra using rods. In this video we use the rods to visually represent unknown values. We explore forming expressions and equations using these rods. There are two practice puzzles at the end of the video.
How To Simplify Ratios
This video explains how to simplify ratios, including how to simplify ratios that include decimal numbers, mixed units and fractions. We also explain how to get a ratio in the form 1:n or n:1. Make sure you have a go at all the practice questions at the end of the video.
Multiplying Decimals Without A Calculator
This video explains how to multiply decimal numbers without using a calculator. We explain two different ways to do this; remove the decimal points (this can be used with grid, line and column multiplication methods) or by keeping the decimal points in place for the lattice method.
Practice questions are at the end of the video.
Video: Rotational Symmetry
This video explains what rotational symmetry is and how to find the order of rotational symmetry of a shape. Practice questions and answers are at the end of the video.
Maths Exam & Revision Tips
This video explains some maths exam and revision tips.
Video: How To Solve Algebra Word Problems
This video will explain how to solve algebra word problems. We explain how to form expressions and equations from wordy questions. The video starts off with simple examples, building up to the more complex age problems. Practice questions are provided throughout the video.
