Max Maths, Year 6, Learn together, Finding the difference between positive and negative integers (1)

The Max Maths Year 6 curriculum introduces students to the concept of finding the difference between positive and negative integers through a practical application involving the height of a river. Students learn to interpret a height marker that measures the river's level in relation to its usual level, which is indicated by the 0 mark. The curriculum includes a table that details the river's height for each month, with levels above 0 representing positive integers (indicating the river is above its usual level), and levels below 0 representing negative integers (showing the river is below its usual level).

To help students grasp the concept, the material provides an example comparing the river's height in March, which is 4 meters above the usual level, with its height in June, which is 2 meters below. By using a number line, students can visually count the steps needed to move from the height in March to the height in June, resulting in a difference of 6 meters. The curriculum further illustrates the concept with real-world scenarios, such as the river rising 2 meters above its usual level after heavy rainfall, or dropping to 5 meters below during a dry season. These practical examples aim to solidify the students' understanding of how to find the difference between positive and negative integers in a tangible and relatable context.
