In Prep School Geometry, Year 6 students are learning how to calculate angles.
In Maths, our Year 6s are becoming better acquainted with the properties of different shapes. This week, they learnt that the degrees of any triangle add up to 180, no matter how large or small the shape is – with no exceptions to the rule. They now also understand that the angles of a quadrilateral add up to 360, regardless of whether it is a trapezium, rhombus or rectangle.
With this knowledge, the girls were able to solve some geometrical challenges. Together, they worked out unknown angles and made some mathematical connections – if they halved any quadrilateral for example, they would be able to make two triangles.
To help her class remember their angles, including obtuse, acute and reflex, Mrs Darwin also had the students on their feet and acting out different degrees and shapes with their bodies and their arms in the air.
