Nursery Pollock class and Reception Rothko class using scales to explore mass / heaviness and lightness using scales

In Maths the notion of heaviness introduces 'more than. and 'less than' when we consider if an object is heavier than another. 

  

Here, Reception children are looking at Mass and how heavy something is

  

Here, Nursery children were looking at whether an object was heavier than an other.

Both classes were using scales. In one this simply explored the concept of heaviness and lightness, in the other the concept of units of measurement is introduced.
