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.

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 […]
