Angles in a Quadrilateral

Students extend their understanding of angles in a triangles to calculate missing angles in a quadrilateral.  As learning progresses they calculate unknown angles using a combination of angle properties, such as, angles about a point, on a line and in triangle.
Differentiated Learning Objectives
  • All students should understand that a quadrilateral is made up to two triangles and therefore has a sum of 360 degrees.
  • Most students should be able to calculate an unknown angle with a quadrilateral.
  • Some students should be able to prove there are 360° within a quadrilateral by considering external angles

How to Simplify Surds

When learning how to simplify surds students need to understand the difference between a rational and irrational number. Rational numbers include integers and terminating and repeating decimals. They can be written as a fraction with both the numerator and denominator as integers. An irrational number is a number which, in its decimal form does not […]

Plotting Scatter Graphs and Understanding Correlation

To introduce plotting scatter graphs and understanding correlation I ask students to think about the relationships between different variables and to describe how they might be related. Here’s my starter activity which students discuss in pairs then present to me on mini-whiteboards. When the students have had time to discuss the matching pairs we talk […]
