Variety of worksheets to help KS1 students to write analogue and digital for o’clock. For more advanced students, there’s a challenge of finding X hours earlier and later than the time previous. To use this resource most efficiently, print off and fill in some of the analogue times and how many hours earlier/ later. For an even harder challenge, don’t just use o’clock; more advanced students will still be able to work out the solution as they will know only the hour should change. For example, what’s 3 hours later than half past four?
