Max Maths, Year 3, Try it, Halving and doubling odd and even numbers (2)

In a mathematics exercise designed for Year 3 pupils, children are encouraged to practice halving and doubling numbers, with a specific focus on understanding the difference between odd and even numbers. One of the tasks asks the students to halve the number 70. To solve this, students can break down the number into tens and units, making the calculation easier to understand. Once they've worked through the problem, they find that half of 70 is 35. This exercise reinforces the concept that halving an even number, such as 70, results in another even number, which in this case is 35.

Another task challenges students to double the number 47. The exercise begins by breaking down the number into its constituent parts (7 + 7) to simplify the process of doubling. Students then double each part separately, adding them together to find the total. Through this process, they discover that doubling 47 results in 94. This example illustrates to students that when you double an odd number, such as 47, the result is an even number, which is 94 in this instance. The exercise also includes halving the number 82, where students learn to separate the number into 80 and 2, making it easier to find half, which is 41. This activity helps to cement the idea that halving an even number will always produce an even result.
