A simple excel document containing a crossword, with answers, where students read the definitions and clues for an input device, and fill the crossword in with these clues. Ways that this resource can be used... Ask the students to complete the crossword as a starter activity (5-10 minutes). Then ask the students to hilight the input and the output devices in two different colours. Students can then discuss whether the hybrid devices, for example the touch screen, are an input or an output device. Alternatively, after completing a lesson on input and output devices, use this resource as a plenary activity. Who can use this resource? Although this resource is designed for KS3 teaching, it can easily be incorporated into computing or info-tech qualifications, for example OCR, AQA, EDEXCEL etc Info-Tech or Computing specifications at GCSE level.
