You can repeat the phrase '5 and above, round up; 4 and below, round down' until you are blue in the face and yet sometimes it's easier just to show them. Which is why we've created this Year 4 Round to the Nearest 100 PowerPoint! The slides follow a question-slide, answer-slide structure and focus on the questions that are found on the varied fluency and reasoning and problem-solving resources (with different numbers) so you can model rounding to the nearest 100 to your class.
