Year 6 lesson plan: Shape and Space Year group: Year 6 Resources: Interactive Whiteboard or whole-class computer screen display Unit Planning Autumn Term Unit 8 ‘ Shape and Space: Reasoning about Shapes: measures) Unit Planning Autumn Term Unit 8 Resource Sheets Interactive Teaching Programme - Polygons Prepared spreadsheet ‘Properties of Quadrilaterals’ Database facility e.g. Information Workshop PowerPoint presentation ‘Reveal the Quadrilateral’ Vocabulary: quadrilateral, parallelogram, parallel, right angle, adjacent sides, irregular, lines of symmetry Oral and mental objectives (including reference to Framework): To classify quadrilaterals using side/angle properties – NNS Section 6 p. 103 Oral and mental activities (from Unit plans): With ‘Polygon’, have a parallelogram drawn on IWB. Hide. Say to the children that you are thinking of a 2-D shape and want them to ask questions to help them to guess what it is. Say that you can only answer ‘yes’ or‘no’. As the children ask questions, write the properties they find on the board or recorded by ‘scribe’ e.g. four sides, two pairs of parallel sides, four right angles, opposite sides are the same lengths, all sides are the same lengths. Play this game twice, once with reference to a parallelogram and then a rectangle. Ensure that the children know that both these are quadrilaterals. Also ensure that they are familiar with vocabulary such as parallel. Point out this vocabulary. Reveal quadrilateral on ‘Polygon’ and test properties noted using ruler and/or protractor on IWB or computer screen. Main teaching objectives (including reference to Framework): To classify quadrilaterals using side/angle properties – NNS Section 6 p.103 Name and begin to classify quadrilaterals, using criteria, such as parallel sides, equal angles, equal sides, lines of symmetry. Main teaching activities (from Unit plans): Whole Class: Construct using ‘Polygon’ a parallelogram, rhombus, trapezium, kite, rectangle and a square together with their names. Ask the children to describe each in turn and as they do so record the properties, testing with protractor and ruler. Draw out the vocabulary. Point out that squares are regular quadrilaterals and special/particular rectangles. (Unit planning Resource Sheet 8.1 can be used as a reference) N.B. this could be carried out either as a whole class or group activity depending on whether single PCs or IWBs/Computer suite are available Ask the children to draw quadrilaterals on ‘Polygon’ according to certain properties e.g. - has opposite sides equal; - one pair of parallel sides; - one right angle; - equal adjacent angles. In each case ask children to name their quadrilateral. Repeat using the following vocabulary – adjacent sides, irregular, lines of symmetry. Group Activities (including differentiation): Group A: In groups of 2-4, prepare database of quadrilaterals (assumes prior working knowledge of Information Workshop and availability of PCs.) Group B: Fill in prepared spreadsheet ‘Properties of Quadrilaterals.’ On squared paper, draw an example of each named quadrilateral . Plenary: Hide a quadrilateral. Ask the children to guess what it is as you slowly reveal it. Repeat with another quadrilateral if appropriate. Q What shape do I have here? Q How do you know? Q What shapes can’t it be? Encourage the correct use of names and properties in all responses. N.B. If an IWB is available, PowerPoint Presentation ‘Reveal the Quadrilateral’ could be used.
