Max Maths, Year 4, Learn together, Rounding numbers to the nearest 10 or 100

In the 'Max Maths, Year 4' curriculum, students learn the essential skill of rounding numbers to the nearest 10 or 100. This concept is introduced through relatable scenarios that help children understand the practical applications of rounding. For instance, when Toby reads about an attendance of 5,687 people at a football match, he learns to round this number to the nearest 100. The correct rounding in this case is 5,700, as 5,687 is closer to 5,700 than to 5,600. This is represented by the notation 5,687 ≈ 5,700, indicating that 5,687 is approximately equal to 5,700 when rounded to the nearest 100.

Further examples reinforce the concept of rounding. When faced with the number 88, students learn that it rounds up to 90, as it is closer to 90 than to 80. This is expressed as 88 ≈ 90 when rounded to the nearest 10. The process is similar for larger numbers, such as 4,452, which rounds to 4,500, and 8,610, which rounds down to 8,600, both to the nearest 100. These exercises provide children with a clear understanding of how to determine which multiple of 10 or 100 a number is closest to and how to round it accordingly. Through practice, students become proficient in rounding numbers, a fundamental skill useful in everyday calculations and estimations.
