Properties of geometric shapes worksheet

This worksheet, designed for Key Stage 2 students, focuses on understanding and classifying geometric shapes based on their properties. In Activity 1, children are provided with a collection of regular and irregular polygons. They are tasked with choosing six shapes and sorting them into groups according to specific criteria, such as having two pairs of parallel lines or containing no right angles. To visually represent their sorting process, the children can use either a Venn Diagram or a Carroll diagram. This activity can be varied by changing the number of shapes used for sorting, allowing for differentiation according to the students' abilities.

In Activity 2, the children work in pairs with whiteboards and pens. They sit back to back, with one child being the 'describer' and the other the 'listener'. The describer selects a 2D shape and provides verbal clues about its properties, such as having one pair of parallel lines, while the listener draws and tries to identify the shape based on the description without asking questions. Once the listener believes they have identified the shape, they confirm with the describer to see if they are correct. The roles are then swapped to give each child the opportunity to describe and listen. Variations of this activity include limiting the number of clues given, allowing the listener to ask yes-or-no questions, or using a geoboard and elastic bands to create a physical representation of the shapes. The objectives of these activities are to compare and classify geometric shapes by their properties and sizes and to find unknown angles in various triangles, quadrilaterals, and regular polygons.
