Constructing Triangles using Compasses and Protractors

Students learn how about constructing triangles using compasses and protractors using SSS, SAS and ASA.  As learning progresses students are challenged to measure angles and lines to scale and construct quadrilaterals.The start of the lesson recaps symmetry by asking students to identify which shape can not be quarter of a square.  The plenary challenges students to construct an arrowhead using two congruent triangles.
Differentiated Learning Objectives
  • All students should be able to construct a triangle using SSS.
  • Most students should be able to construct a triangle using SSS and SAS,
  • Some students should be able to construct a triangle using SSS, SAS and ASA.

Rounding to a significant figure

January 29, 2019

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

January 13, 2019

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

January 4, 2019

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 […]
