We have been learning to measure in maths.  We have learnt about length, height, weight and mass so far.  We are very skilled in measuring now and we have been extending  the vocabulary that we use to describe and explain.

"The hedgehog has a mass of 4 cubes and it is heavier than the xylophone because the xylophone has a mass of 2 cubes."

"The book is longer than the shoe, the bamboo is the longest."
