Today in their maths lesson, Year 1 were estimating and measuring the mass of objects using a balancing scale and cubes. They learnt that they should stop adding/counting cubes when the scale has balanced as this means that they have calculated the mass. They did really well with this and their estimates got better as the activity progressed as they could reason better e.g. I think this object will be 30 cubes because it feels heavier than the scissors which were 16 cubes.
