Circles

In Numeracy we have been learning more about circles, we have been using the vocabulary arc and chord. We have sayings to help us remember them “Arthur the ant walks round in an arc” and “Chris the cricket jumps across in a chord.” We have also been learning about how a circumference is a special kind of arc that goes all the way round the outside of a circle, and a diameter is a special kind of chord that always passes through the centre of the cirle. In the pictures, the children are measuring the lengths of circumferences and diameters.
