In Max Maths for Year 2, students are given the opportunity to practice rounding numbers to the nearest 10 with the 'Try it' section. This concept is essential for developing estimation skills and number sense. For instance, when asked to round the number 82, students learn that it is closer to 80 than to 90. Therefore, the rounded approximation of 82 is about 80 when considering the nearest 10. This is represented by the notation 82 ≈ 80, indicating that 82 is approximately equal to 80 after rounding.

Similarly, when rounding the number 56, students determine that it is closer to 60 than to 50. As a result, the rounded figure for 56 is approximately 60. The exercise reinforces the rounding rule that when a number is exactly halfway between two multiples of ten, such as 35 which sits between 30 and 40, the number is rounded up to the next ten. Therefore, 35 is rounded up to 40, expressed as 35 ≈ 40. The 'Let’s Try It' activity further encourages students to apply this knowledge by using a number line to round numbers themselves, such as rounding 42 to the nearest 10, which involves identifying whether 42 is closer to 40 or 50 on the number line.
