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.

Rounding to a significant figure

When I teach rounding to a significant figure, I ask the class to discuss in pairs or small groups a definition for the word significant.  It is a word that all the students have heard before but not all are able to define. After 2 or 3 minutes of conversation I ask the students to […]

Calculating Instantaneous Rates of Change

When calculating instantaneous rates of change students need to  visualise the properties of the gradient for a straight line graph.   I use the starter activity to see if they can match four graphs with their corresponding equations. The only clue is the direction and steepness of the red lines in relation to the blue line […]

Converting Between Fractions, Decimals and Percentages

Fractions, decimals and percentages are ways of showing a proportion of something.  Any fraction can be written as a decimal, and any decimal can be written as a percentage.  In this blog I discuss how to use the place value table and equivalent fractions to illustrate how fractions, decimals and percentages are connected. You can […]
