Are you looking for a resource to show your children how to compare different durations of time? Take a look at our Year 2 Compare Durations of Time Teaching PowerPoint.
Helpful images show your children how to use a clock face or number line to work out the duration between two times before showing children how to compare two or more times. There are questions throughout that you can use for modelling or for checking your children's understanding. The PowerPoint ends with a couple of reasoning and problem questions for you to work through together.
