Area of Irregular Shapes

Students learn how to find the area of irregular shapes by grouping.  As learning progresses they are challenged to consider the range of accuracy for their solutions and more complex irregular areas.  An accompanying worksheet that matches the interactive whiteboard presentation is included to aid pace.
Differentiated Learning Objectives
  • All students should be able to measure an irregular area involving non rectilinear polygons.
  • Most students should be able to measure an irregular area of shapes with curved edges.
  • Some students should be able to measure a irregular areas of compound 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 […]
