Angles worksheet

In an engaging worksheet activity designed for Key Stage 2 students, the focus is on understanding and calculating angles. The first activity involves working in pairs to find missing angles on a straight line. Each pair receives a diagram with a straight line that has some angles missing. The children collaborate to calculate the missing angles and then share their methods with another pair, fostering peer-to-peer learning and reinforcing their understanding of the concept that angles on a straight line sum up to 180 degrees.

The second activity follows a similar structure, where children work in pairs to determine missing angles around a point. After receiving a diagram with a central point from which several angles emanate, the pairs use their knowledge that the total angles around a point add up to 360 degrees to find the missing values. Once solved, they explain their process to another pair, consolidating their learning. In the third activity, the children engage in a hands-on exercise using paper, scissors, protractors, and rulers. They create an equilateral triangle, label its angles, and then cut it into three separate angles. By arranging these angles on a straight line on another sheet of paper, they can visually confirm that the angles sum to 180 degrees. This exercise prompts them to explore whether this principle applies to other types of triangles as well. The objective of these activities is to help students recognise angles at a point, on a straight line, or those that are vertically opposite, and to develop the skills to find missing angles effectively.
