### 2 | Introduction to simultaneous equations with picture-based puzzles

This lesson is intended as an introduction to simultaneous equations, where students solve picture-based puzzles without using formal algebra.

The idea is that the following lesson they can look at equations given algebraically and see how it is effectively the same thing.

### 4 | Solving equations graphically KS3 worksheet

This is a worksheet with some questions on solving simultaneous equation in three sections.

Section one is two linear equations, section two is a quadratic and y=n, and section three is the extension which is a quadratic and y=mx+c.

There is a RAG table for students to mark their progress and this can be amended depending on how far you want to go. Students will need to plot graphs and estimate solutions as not all are integers.

### 7 | Exploding linear and non-linear equations for KS4

This is a set of six sheets of increasingly difficult simultaneous equations designed to make students think and discuss how to work through their solutions by giving them different parts of the process.

They include simultaneous equations that involve a linear and a non-linear equation.

This is also designed to stretch at GCSE or could be used at the start of A level.

### 8 | How to solve simultaneous equations graphically

This KS3 or GCSE PowerPoint activity has a couple of simple slides showing what we mean by solving simultaneous equations, and how to solve them graphically.

There are some questions and answers at the end. It assumes students can plot y=mx + c style equations.

### 9 | Simultaneous equations GCSE topic review

Ideal for students who are revising simultaneous equations, these revision sheets have exam-type questions which gradually increase in difficulty.

The last questions have an extra twist.

### 10 | Simultaneous equations graphically

This lesson will show students how plotting two linear equations in x and y allows them to solve simultaneous equations.

The PowerPoint has a full explanation as the starter and there is a sheet of questions for students to practice.

Before doing this task they should have covered algebraic versions of simultaneous equations, as well as linear graph plotting.

### 11 | Real-world simultaneous equation example worksheet

Trying to find a real-life example of where we might solve simultaneous equations graphically I came up with this. Students have to plot to linear graphs and find the point of impact.

You could bring in Pythagoras and find out if the two bodies were travelling at the same speed would they actually collide, but I wanted to keep the worksheet to one side of A4.

### 26 | Simultaneous equations and graphs lesson

This full lesson introduces solving simultaneous equations using graphical methods.

The starter is a kinaesthetic activity where pupils order themselves according to the value of the expressions they are holding (answers and values to substitute are shown on the board).

For the main activity they pick out graphs to find pairs of solutions to (at first by trial and error) – which later they draw and solve graphically.
