Lesson details
Key learning points
- Vector graphics are made from shapes described by coordinates, not pixels.
- Vector illustrations are built using simple shapes.
- Vector graphics use z-order to show which shapes are in front and are visible.
Keywords
Vector graphic - an image made up of lines and shapes
Z-order - the order of overlapping objects
Layer - the level on which an object (e.g. text, shapes and photos) can be placed relative to other objects

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.
