Problems with Circular Shapes

Students use the circumference and area of a circle to solve a variety of problems with circular shapes.  Throughout the lesson students develop their calculator and non-calculator techniques as solutions are presented in terms of pi or decimals rounded to three significant figures.

The start of the lesson recaps finding the circumference and area of a circle as a decimal and in terms of pi.  The plenary challenges students students to calculate the perimeter and area of a circle and semi-circle.

Differentiated Learning Objectives
  • All students should be able to solve problems involving the perimeter of circular shapes.
  • Most students should be able to solve problems involving the perimeter and area of circular shapes.
  • Some students should be able to set up and solve equations to model the area and perimeter of circular 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 […]
