Classifying geometric shapes worksheet

The KS2Gems2022 worksheet presents a series of engaging activities designed to help Year 6 students compare and classify geometric shapes, particularly focusing on quadrilaterals and triangles. In Activity 1, children work in pairs with one describing a 2D shape using its properties, while the other listens and sketches the shape based on the given clues, without asking questions. This activity encourages communication and conceptual understanding. Variations include limiting the number of clues or allowing the listener to ask yes-or-no questions. Activity 2 involves children selecting six shapes and grouping them using criteria such as the presence of parallel lines or right angles, and then representing their groupings with either a Venn or Carroll diagram, with the option to adjust the number of shapes used.

Further activities build upon these skills by asking children to sort different triangles (Activity 3) and quadrilaterals (Activity 4) using a Carroll diagram to record their criteria. In Activity 5, students use squared paper and rulers to draw lines and construct various types of triangles, checking each other's work for accuracy. Activity 6 extends this to drawing rectangles and other quadrilaterals, starting from a 5cm line. Activity 7 introduces a hands-on approach where children use art straws and scissors to create quadrilaterals and calculate their perimeters, with variations in straw length and number. Activity 8 challenges students to make geometric shapes with two straight cuts in a paper square, exploring which shapes can be created from a selection of paper squares. Finally, Activity 9 explores the possibilities of folding an A4 paper into different shapes, such as a square, equilateral triangle, kite, rhombus, and regular hexagon. Each activity aligns with the objective to enhance students' ability to compare and classify shapes based on their properties and sizes.
