Max Maths, Year 2, Learn together, Measuring mass in grams and in kilograms (4)

In this engaging lesson from Max Maths for Year 2, children learn about measuring mass in both grams and kilograms. The lesson introduces the concept of mass using everyday items that the children are likely familiar with, such as milk, chicken, watermelon, and flour. Each item's mass is presented in a clear and visual manner, with scales showing the weight in kilograms on one side and the equivalent in 500-gram increments on the other side. For example, the milk is shown to have a mass of 1 kilogram, which is also expressed as '1 kg' for the children to understand the written representation of mass.

As the lesson progresses, children are shown how to measure heavier items, with the mass of the chicken being 2 kilograms ('2 kg'), the watermelon at 3 kilograms ('3 kg'), and the flour at 4 kilograms ('4 kg'). This step-by-step approach helps to reinforce the concept of mass and the difference between grams and kilograms. Through these examples, children are encouraged to recognise the pattern that 1 kilogram is equivalent to 1000 grams, making the connection between the two units of measurement. The visual aids and repetition of the mass values in both numerical and written form aim to support the children's learning and retention of the information.
