If some or all of your class are dab hands at converting units of time, and you're looking to give them a bit more of a challenge, check out this Year 5 Convert Units of Time Discussion Problem worksheet! The two problem-solving questions are nicely open-ended, and one even brings in a little touch of reasoning at the end. The tasks are designed to get children to apply their knowledge to more complex problems, while bringing in the opportunity to use mathematical talk.

If you feel it suits a child better, the sheet can also be done solo or with an adult as the discussion partner. It's up to you. Whatever you choose, be sure to make use of the example answer sheet we've included! You or your children can use it to check they've got the right idea!
