A lesson created to support pupils in getting to know and use their calculator ahead of GCSE exams. Includes starter & plenary group memory exercises, pair activity to find buttons using co-ordinates and then individual task to work through different buttons needed at GCSE. The slides are aimed at Higher paper candidates but could be used for foundation by removing the Higher topics. Instructions on what to print out for the lesson are on the last slide. NOTE: This is based on using a Casio FX 83/85GT calculator but could be adapted for other models.
