Form and Solve Quadratic Equations

Form and Solve Quadratic Equations

Students learn how to form and solve quadratic equations from geometry problems. Problems include finding the area of a rectangle with algebraic lengths to setting up an equation from similar shapes. The start of the lesson recaps finding the area of composite shapes with algebraic lengths as this is needed throughout the lesson. The plenary challenges students to derive and solve a quadratic equation from the surface area of a cuboid. Differentiated Learning Objectives All students should be able to form a quadratic equation from a rectilinear area. Most students should be able to use geometrical facts to set up and solve a quadratic equation when a = 1. Some students should be able to form and solve a quadratic equation from geometrical facts.

Changing the Subject

Changing the Subject

This is 2 lessons on changing the subject of a formula (the first lesson was observed and rated Outstanding). It was designed to introduce high ability year 8's to this skill, but the lesson could be used with anyone! The second lesson requires additional resources, but this is explained in the teacher notes.

Linear Graph Introduction

Linear Graph Introduction

The first lesson of the topic. Introducing Linear Graphs and y=mx+c for a high ability year 8 class. Sheets can be complied into a booklet to created a scaffold-ed resource to be used throughout the lesson. PowerPoint creates opportunities for AfL through the use of MWB. Each question has a timer attached to it that can be activated by clicking in presentation mode.
