Max Maths, Year 2, Learn together, Comparing masses (2)

In a Year 2 mathematics lesson from Max Maths, students are encouraged to explore the concept of mass by comparing the weight of different objects. The activity involves observing two balances, each with a set of objects, and determining which object is the heaviest and which is the lightest based on their positions on the balances. The lesson provides a clear and logical sequence to deduce the weight of the objects relative to each other.

The provided example uses three objects: a tissue box, a teddy bear, and a shoe. Students are guided through the process of comparison. It's explained that the tissue box is lighter than the teddy bear, and since the teddy bear is lighter than the shoe, it follows that the tissue box is the lightest object of the three. By the same logic, the shoe is identified as the heaviest object. This activity not only teaches children about mass and comparison but also encourages logical reasoning and the use of transitive relations to draw conclusions about the relative weights of objects.
