# Geometry

This week, in maths lessons, the children in year 6 have been working on geometry. They developed their learning about circles so that they understand the words “radius”, “diameter” and “circumference”. Then, they moved on to looking at the connection between the radius and the diameter. The radius is half the diameter. Following this, the children drew circles with a given radius/diameter.

In this unit of work, the children also looked at drawing shapes accurately. Firstly, they drew angles and lines accurately using protractors and rulers before drawing given shapes. Interior angles were the next area of learning. The children learnt that the number of triangles a polygon can be split into is two fewer than the number of sides. Multiplying the number of triangles by 180° gives the sum of the interior angles in the polygon. Using this information, angles of polygons were calculated. Finally, the children attempted to draw regular polygons. Great care was taken with this and there were some very accurate regular shapes drawn.
