Max Maths, Year 2, Learn together, Rounding numbers (2)
Maths Resource Description
In the Max Maths Year 2 curriculum, students learn the concept of rounding numbers to the nearest ten. This skill is essential for simplifying numbers and making estimations easier. For example, when asked to round 82 to the nearest 10, students are shown that 82 is closer to 80 than to 90. Therefore, the rounded number is approximately 80. This is represented by the equation 82 ≈ 80, indicating that 82 is approximately equal to 80 when rounded to the nearest 10.
Another example provided to the students is rounding the number 56. In this case, 56 is closer to 60 than to 50, hence it rounds up to approximately 60, shown as 56 ≈ 60. Additionally, the students learn about the special case of rounding when the number is exactly halfway between two tens. For instance, 35 is equidistant from 30 and 40. In such situations, the rule is to round up to the higher ten, resulting in 35 being rounded to approximately 40, or 35 ≈ 40. To practice this concept, students are encouraged to use a number line to help them round numbers, such as rounding 42 to the nearest 10. With the number line showing 30, 40, and 50, students can visually see that 42 is closer to 40 and would, therefore, round down to 40.
