ICT at key stages 1 and 2 (Year 5)
Unit 5E: Controlling devices
Section 3: SHORT FOCUSED TASKS
|
|
Objectives |
| Children should learn: |
- key idea: to control more than one output device
- techniques: to use simple procedures to control more than one output device
- to use simple control language to activate multiple devices concurrently

Outcomes |
|
Children: |
- Show the class a simple traffic light set-up, using a pre-built model or three different coloured bulbs, and discuss the sequence of lights. Ask the children to work in pairs to produce a story board of a pelican crossing. The storyboard should show the lights before, during and after the button is pressed.
- Ask each pair to write the control language to produce the correct sequence. They will need to use language learnt in the previous exercise and will need to know how to turn on more than one output at a time, for example to produce red and amber at the same time. Children should be encouraged to write separate small procedures for each part of the sequence, for example stop, wait and go. The children should then enter and test their procedure on the computer. They should record any amendments and describe the results. Finally, ask them to get the computer to repeat the sequence a number of times.
|
|
- write a sequence to produce a recognisable event
- recognise the need for precision when writing a number of procedures in one sequence of instructions
|
|
Points to note |
Discuss what happens at a junction with more than one set of lights. What would happen if a procedure allowed all cars to go at the same time at a set of crossroads? Also discuss the difference between a set of lights and a pelican crossing, for example a pedestrian pressing the button.
