Finding any length of a Right-Angled Triangle

Key stage 3 mathematics for using Pythagoras' Theorem to calculate any length of a right-angled triangle.   Learning progresses from working with Pythagorean Triples to calculating the area of a right-angled isosceles triangle when only the hypotenuse is given.
Differentiated Learning Objectives
  • All students should be able to calculate a smaller side of a Pythagorean Triple
  • Most students should be able to calculate any side of a right-angled triangle using Pythagoras’ Theorem
  • Some students should be able to apply Pythagoras’ Theorem to composite triangular shapes.

Comparing Datasets using the Mean and Range

In my experience, students, in general, find the concept of a mean straightforward to calculate and understand. However, the mean alone does not provide a complete picture of a set of data. To achieve this, a measure of spread is also required. The range is the simplest measure that can be used for this. Not […]

Solving Problems with Angles in Parallel Lines

Solving problems with angles in parallel lines is like solving a murder mystery.  One clue leads on to the next and the next until the murderer is found.  However, it doesn’t end there.  The detectives need to explain their reasoning in court using the relevant laws and procedures should the murderer plead not guilty.  If […]

Solving Two Step Equations using the Balance Method

An equation is when one expression, or term, is equal to another.  To solve an equation means to find the value of the variable (represented by a letter) that makes the two expressions equal.  There are two types of equations for secondary school mathematics, linear and none-linear.  In this blog I write about how I […]
