Using graphs to represent lengths and heights
Lesson details
Learning outcome
I can represent lengths and heights on a graph and use them to solve problems
Key learning points
- Information about length and height from a table can be represented in a bar graph.
- Information represented in a bar graph can be used to solve problems.
Keywords
Graph - A graph is a visual way of showing information. A Bar Graph uses bars of different lengths or heights to represent information.
Axis - An axis on a graph is a fixed measuring line that runs horizontally (left to right) and/or vertically from zero:
Common misconception
Mistakes may be made on comparison problems. E.g. how much further does one child jump than another?
When we compare, we are finding the difference. To find the difference, we need to subtract the smaller value from the larger value.
Teacher tip
Bar graphs are used to present discrete data. Data related to length and height might be considered continuous but the way it is used here is for comparison and is a measurement taken at one point in time and so is considered discrete data.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
