Max Maths, Year 6, Learn together, Finding the difference between positive and negative integers (2)

In a Max Maths Year 6 lesson, students delve into the concept of finding the difference between positive and negative integers, with a focus on real-world applications such as comparing river heights at different times of the year. For instance, they examine the difference in height between the months of June and August. In June, the river stands 2 metres below the usual level, while in August, it is 7 metres below. By visualising this on a number line and counting the steps from June's position to August's, students can easily determine that the difference in height between these two months is 5 metres.

Further practice is provided through an exercise titled 'Let's Try It', where students are presented with a table listing river levels for each month in another country. The levels are given in metres and include both negative and positive integers, representing the river's height below or above the usual level, respectively. The task involves rearranging the table to display the river heights in ascending order, which helps students understand the sequence of integers and the concept of numerical order across positive and negative values. This exercise not only reinforces their understanding of integers but also hones their organisational and comparison skills.
