Shape Investigations in the Playground

Print Friendly, PDF & Email

Today in Asia class we revisited 2D shapes in our Maths lesson. We particularly focused on explaining the difference between regular and irregular 2D shapes, and learned some of the ways of telling if a shape is regular:

– all its sides are the same length

– all its angles are equal

– it has the same number of lines of symmetry as it has sides

We looked at the shapes painted on the playground and identified these features, in order to decide whether each shape was regular or not. Being able to spot all the lines of symmetry was tricky, but we persevered!
