If learners need to spend 5 minutes getting to grips with a spreadsheet or a simple piece of tech - do it . . . this is what we call embedding technology!!! If you don't have the technology in the classroom - ask them to complete it for homework and then share what they have done in the next lesson.
Extra note for spreadsheets:
If you are using spreadsheets that automatically do things where the user punches in the numbers and it works it out (e.g. risk assessments, sport analysis etc)- get learners to punch in different sets of numbers according to different scenarios and then peer assess. Everyone eating the same flavour ice cream can be terribly dull - try creating an ice cream parlour instead!
