This Year 4 Complete and Incomplete Circuits Worksheet follows on perfectly from the second lesson in our Year 4 Electricity unit, What is a Circuit?

Children are provided with four pictures of components and asked to draw a complete and an incomplete circuit. This simple but effective task is perfect for checking their understanding of the lesson content. At this stage, children are not expected to use the recognised symbols for components.

An answer page is included to encourage peer or self-marking and discussion. Download it now!
