Constructing Angle Bisectors

Students learn how to construct angle bisectors using a pair of compasses and a straight edge.  The lesson covers bisecting acute, obtuse and right angles to constructing perpendicular bisectors and reflex angles.
Differentiated Learning Objectives
  • All students should be able to construct an acute angle bisector.
  • Most students should be able to bisect an acute, obtuse, right angle and straight line.
  • Some students should be able to find the equidistant point in a polygon using angle bisectors.

Solving Inequalities using a Number Line

Students should be able to represent the solutions to an inequality on a number line, using set notation or as a list of integer values.  Here’s how I teach using the balance method for solving inequalities using a number line. Matching inequalities, Number sets and Number Lines At the start of the lesson students recap […]

Practical Tips for Using Mini-Whiteboards in a Mathematics Lesson

In this blog I will share some practical tips for using mini-whiteboards in a mathematics lesson.  I use mini-whiteboards nearly every lesson because they help the students show me the progress they are making.  When I understand what the misconceptions are I am able to address them in subsequent examples as part of my feedback.  […]

Showing Progress during a Mathematics Lesson

Demonstrating student progression during a mathematics lesson is about understanding the learning objective and breaking that down into explicit success criteria. Using Success Criteria Take, for example, a lesson on calculating the area of compound rectilinear shapes. The intended learning objective was written on the main whiteboard. Success criteria were used to break down the individual […]
