Working with multiple objects
Lesson details
Learning outcome
I can work with multiple objects to create a vector drawing.
Key learning points
- In vector graphics, every shape (like a square or circle) is called an object.
- You can use tools to line up objects neatly or spread them out evenly (distribute).
- Grouping lets you move or change several objects at once, as if they were one shape.
- You can use tools to join shapes, cut them apart or create new outlines.
Keywords
Object - something that is uniquely identifiable and has attributes
Group - a set of objects placed together
Combine - join two or more objects together as one entity
Union - a way of combining multiple selected objects into a single, unified shape
Common misconception
Grouping objects is permanent.
Grouping objects can be reversed using ungroup. Combining objects is harder to reverse; only undo fixes combining.
Teacher tip
You need to be familiar with using the alignment and distribution tools in Inkscape, as well as the the logic of union, difference and intersection.
Equipment
Pupils will need access to a device with vector graphic editing software. Examples in this lesson use Inkscape https://oak.link/inkscape

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.
