Parts of a circle worksheet

In a series of engaging activities, KS2 students are invited to explore the geometry of circles using simple tools such as paper, compasses, and protractors. Activity 1 starts with a straightforward task where children are asked to draw circles with given diameters or radii. After completing their drawings, they swap papers with a partner to check the accuracy of the dimensions. This exercise not only reinforces their understanding of circle measurements but also encourages peer-to-peer learning and verification.

Building on their skills, Activity 2 introduces an intriguing challenge: drawing concentric circles, each with a diameter or radius 5mm smaller than the previous one. Students are prompted to consider how many such circles can fit within the first circle they draw. Afterward, they again exchange papers with a partner to review the dimensions. The third activity adds a creative twist by asking the students to draw a circle with a 5cm diameter and then use it to construct the shape of a 50p coin, integrating protractors and the coins themselves into the learning process. Finally, Activity 4 encourages students to create a geometric design by drawing a circle with a 9cm radius and marking six equidistant points along its circumference. With these points as a guide, they use a ruler to draw a complex geometric pattern. The objective of these activities is clear: to help students illustrate and name parts of circles, such as the radius, diameter, and circumference, and understand the fundamental relationship that the diameter is twice the length of the radius.
