Angles of Elevation and Depression

Students learn how to construct and use scale drawings to measure angles of elevation and depression and unknown lengths. As learning progresses students are challenged to decide their scale and investigate similar shapes.
Differentiated Learning Objectives
  • All students should be able to construct a scale drawing of a triangle.
  • Most students should be able to construct a scale drawing of a triangle to measure a length or angle.
  • Some students should be able to draw and measure line segments and angles in geometric figures, including interpreting scale drawings.

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 […]
