A simple resource to teach the students about sequencing and flow charts at KS3, it includes all the terminology needed as well as the correct way to develop a flow chart using the correct symbols. Also included is a task related to the use of a "Big Trak" which was used to programme a sequence of instructions. I used this for 2 lessons to get the students used to the ideas of flow charts and sequencing prior to programming. **If Big Traks are unavailable you can also switch this task to something like Flowol as the resource will have already given insight into flow charts
