Graph Skills: Lesson 3- Calculating the value of one square on a graph in order to plot coordinates

This lesson is lesson three of a scheme of learning which focuses on supporting students become more proficient in graph skills and data handling. Students find it quite hard to find the exact place to plot their data point. This is often because they are unsure what one square on a graph represents and how to work this out. This particular lesson therefore focuses on helping students find a permanent strategy to find the value of one square on the graph and help them both plot graphs and extrapolate data from graphs.

Graphs have a number of skills and so this scheme aims to break down these skills into more manageable sections. There is a tracker which documents a students journey as they practise these key skills, practise worksheets and a practise exam question, as well as a very clear PowerPoint guiding students through.

The idea is that students have lesson time to practise the skill through modelling and example questions, they then self assess their work and add their mark for that skill on the tracker. They then practise that skill only on their practise question. This has two levels of ability one graph with decimal places and one without. Over the lessons this exam question should become more and more accessible.
