Properties of Triangles

Students learn about the properties of triangles.  They explore the various unique triangles that can be made on a square and isometric grid.To begin the lesson students recap the names of common 2D shapes.  In the development phase they are challenged to create siz unique triangles on a 3 by 3 grid.  The end of the lesson challenges them to consider why some properties in triangles are impossible.
Differentiated Learning Objectives
  • All students should be able to identify an isosceles, equilateral, right-angle and scalene triangle.
  • Most students should be able to know the properties of different types of triangles.
  • Some students should be able to create all the unique triangles on a 4 by 4 grid.

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 […]
