Circles resources

Students calculate the distance travelled by the tips of the hands on a clock, and calculate the speed of one of the tips.

Students use a diagram of, and information about oranges packed in a cylinder to calculate height, area and volume.

Students calculate circumference, circular and square area of a road sign.

Students are required to identify right angles in a series of diagrams, using their knowledge of angle properties relating to circles and tangents.

Students use the angle between a tangent and a radius property and the base angles in an isosceles triangle property to find an unknown angle and to explain why line segments are of equal size.

Students use the angle-in-a-semicircle property, and the sum of the angles in a triangle to find unknown angles.

Students use their knowledge of the angle between a tangent and radius property and the sum of the angles in a quadrilateral to work out unknown angles in a diagram and explain their workings.

In this practical task, students work in small groups to present a dance based on geometric concepts.

Students identify the parts of a circle that lines on familiar signs and objects make.

Students use the given the radius to draw each circle on a bulls-eye target.

Students write short paragraphs using geometrical terms to describe two pictures. The terms equilateral, scalene, and isosceles are to be used to describe a castle. The words circumference, diameter, and radius are to be used to describe a bicycle.

Students calculate the size of marked angles using their knowledge of angle properties: the angle between a tangent and a radius, the sum of angles in a triangle and the sum of angles in a quadrilateral.

Students calculate the lengths of circles and straight lines on an oval athletics track from its given radius and total length, and show their working.

Students answer questions about a ball travelling a number of full circles in a game of swing ball.

Students use known diameters of tins to work out the floor area of a carton and a given number of tins.

Students calculate area of colours and the perimeter of a flag.

This task is about finding the circumference of a circle using two different radius measurements.
