Max Maths, Year 5, Learn together, Comparing readings on different scales (2)

In a Year 5 mathematics lesson from Max Maths, students delve into the concept of comparing readings on different scales, specifically focusing on measuring mass. The task presents two different scales, one in grams (g) and the other in kilograms (kg), and asks students to determine the mass being measured. The gram scale is detailed with increments of 1000 grams, marked with intermediate divisions that represent 100 grams each. Observing the position of the arrow, which lands on the sixth division past the 6000-gram mark, students can deduce that the mass shown is 6600 grams.

Similarly, the kilogram scale is divided into segments, each representing 1 kilogram, with five smaller divisions between them. Each of these smaller divisions corresponds to 100 grams. When the line stops at the sixth division beyond the 6-kilogram mark, it indicates a mass of 6.6 kilograms. Through this exercise, pupils learn that 6600 grams is equivalent to 6.6 kilograms, demonstrating that despite the different units and scale representations, the actual mass measured remains consistent across both scales. This comparison not only reinforces their understanding of mass measurement but also the relationship between grams and kilograms.
