Maths

In this unit pupils will choose, use and compare appropriate standard units to estimate and measure length/height mass, temperature, capacity to the nearest appropriate unit.  In the future unit pupils will use weighing scales up to 1kg and tools to measure volume and capacity up to 1 litre. They will measure mass from 0 to above 1kg and measure volume from 0 to above 1 litre. 

In the prior unit pupils learned that polygons could be described sorted compared and named according to the number of sides and vertices They described 3D shapes finding different ways to sort and compare them In this unit pupils will choose use and compare appropriate standard units to estimate and measure length/height mass temperature capacity to the nearest appropriate unit
