Carroll diagrams use two headings that are the opposite of one another (mutually exclusive), e.g. ‘has at least one triangular face’ and ‘has no triangular faces’ ‘is a prism’ and ‘is not a prism’ ‘is regular’ and ‘is irregular’ ‘has at least one pair of parallel faces’ and ‘has no pairs of parallel faces’. has at least one triangular face has no triangular faces RememberRemember thatthat thethe facesfacesare are Let’sLet’s thinkthink aboutabout sortingsortingthethe mademade fromfrom 2-D2-D shapesshapes (two(two shapesshapes accordingaccording toto differentdifferent dimensions)dimensions) andand solidssolids areare calledcalled criteria…criteria… 3-D3-D shapesshapes (three(three dimensions).dimensions). © hamilton-trust.org.uk 3Year 5 Identify, visualise and describe properties of 3-D shapes; Sort 3-D shapes according to their properties.
