  2. Today we will… • Be aware of the key ideas underpinning the two strands of geometry in EYFS, KS1 and KS2; • Explore challenging practical tasks for applying knowledge in shape and space; • Look at coordinate representation and use of angle; • Be able to teach further aspects of 2D shape, including transformations (translation, rotation, reflection and scaling) Associated issues for teaching Explore aspects of position and movement using ICT. Consider the role of a plenary within any lesson structure What do success criteria look like in mathematics?

  3. Maths Assignment

  4. Bar Model representations: (KS1 problems) Additive Reasoning BUILD: • There are 4 yellow flowers and 3 blue flowers – how many altogether? • There are 5 lollies. Jess eats 2. How many are left? • 6 + [] = 17 altogether QUESTION: (Create your own) “John has 7 balls. Mark has 5 more…” “Beth has 6 balls. Emily has 3 less…” • COMPARE: • There are 5 red cars and 3 yellow cars, how many more red cars? • The string is 4cm, the ribbon is 8cm. How much shorter…?

  5. Number Rods (Cuisenaire) Multiplicative Reasoning What problem could this bar model be showing? What could this bar model be showing? Playing with algebra…? Working backwards…

  6. Purposeful Plenaries • What are plenaries for? • How have you seen them used? • What features make for a successful plenary?

  7. Mastery in Geometry What’s it all about? What's involved? What would you expect to see re. ‘Big ideas’ in Geometry, across the primary years & in different year groups? What would you expect primary learners to be able to do and understand?

  8. Interactive Teaching Programs(ITPs)

  9. Glossary Definitions What's the same, what's different? • How would you define these quadrilaterals: • Parallelogram • Rhombus • Rectangle • Square • Oblong • Kite and inverted kite (delta) • Trapezium Triangle, square, rectangle, oblong, quadrilateral, pentagon, hexagon, octagon, circle, semicircle, cube, cuboid, pyramid, cone, cylinder, prism, sphere, hemisphere, face, edge, vertex/vertices, surface, solid, side, straight, curved, diagram, right-angled, symmetrical, 2-D shape, two-dimensional, 3-D shape, three-dimensional, describe, property How do we compare to www.amathsdictionaryforkids.com ?

  10. Sorting • What different properties of shape are expected? • Use Tree, Venn and Carroll Diagrams to sort shapes… [How are these different sorting diagrams linked?]

  11. National Curriculum‘Geometry’ • Two aspects: • Properties of shape • Position and direction TASK 1 • Track progression from [EYFS] Y1 to Y6 • Is progression clear? • Are there any gaps? Task 2 • Focus on the expectations for your year group…? • Clear learning points?

  12. ELG 12: Children use everyday language to talk about …position, distance, to compare quantities and objects and to solve problems. They recognise, create and describe patterns. They explore characteristics of everyday objects and shapes and use mathematical language to describe them.

  13. Mastery Read the ‘Big Ideas’ for your year group… What understandings are identified? Do they meet your expectations?

  14. Mastery Consider the examples in your year group. Choose an example to use in a plenary or HOT/ COLD task, how might you scaffold the learning within the lesson to enable success?

  15. Geometry – D Haylock • Two aspects: • Moving or changing shapes • Classifying shapes • Fundamental concepts: • Transformation • Equivalence We ask learners: “How are they the same? How are they different?” Copy this shape onto a whiteboard… How is your shape compared to mine?

  16. The same but different A B C D How are these shapes the same? How are they different? A ‘transformation’ that changes a shape into a congruent shape is called a ‘congruence’. That is; a translation, a reflection, a rotation.

  17. Explore Discuss and sketch models and images for: • Translation • Reflection • Rotation • Tessellation (and packaging) • Patterning • Matching • Sorting and classifying • Enlargement [Y6 R&P] ‘…similar shapes where the scale factor is known or can be found.’ What other ‘shape’ examples...?

  18. Coordinates-Plotting Coordinates squares on a grid. Draw … • A tick B4 • A cross E3 • A triangle C2 5 4 3 2 1 A B C D E

  19. 14 13 12 11 10 Real Life Ordnance Survey Maps Locate ‘interesting features’… give 6 fig coordinates for others to find them. e.g. 042 123 Means X: 04 and 2 ‘tenths’ Y: 12 and 3 ‘tenths’ 04 05 06 07 08

  20. Using a Protractor • Can you create Success Criteria to “use a protractor to measure an angle”? (Expectations: to nearest 10° or 5° or 1°) • What are the main teaching points? • How might you model this? Woodlands Junior – “What’s My Angle?” http://resources.woodlands-junior.kent.sch.uk/maths/shapes/angles.html

  21. fd 100 bk 100 rt 90 lt 90 cs seth 0 Repeat ? [fd 30 rt 90] pu / pd (pen up/down) pe / ppt (en erase/paint) Create a set of commands to draw a: Square Rectangle Other regular shapes Block letter of the alphabet A spirograph MSWLogo

  22. 2D challenges Tarsia Jigsaw Investigate ITP's – ‘Isogrid’, ‘Polygon’, ‘Area’, ‘Coordinates’ What different shapes can you make by folding A4 paper? Isogrid ‘Dot to Dot’ - use a triangular array of 15 dots to draw different triangles. How many are there? 3D challenges The 12 Pentominoes – Which make the net of an ‘open cube’? Nets Challenge – choose any 3d shape. Create its net to ‘tightly wrap’ it Online searches: ‘Tangrams’/ ‘Tesselations’/ ‘MC Escher’/ ‘Origami’/ ‘Transformations’/ ‘Platonic Solids’ Use the mathematical equipment to accurately draw: equilateral triangle, square, isosceles triangle, hexagon, pentagon…. Nrich - Properties of shape Activities - ‘airnets’; ‘transformations on a pegbd’; ‘a shapely network’; ‘property chart’; ‘making tangrams’ Google– ‘Soma Cube’; ‘Spiral in a square’ Online links: http://www.theguardian.com/science/alexs-adventures-in-numberland/2015/aug/10/attack-on-the-pentagon-results-in-discovery-of-new-mathematical-tile Create a glossary that names and defines the properties of 2d/ 3d shapes You will feedback!

  23. MATHS TASK Prepare 15 maths questions with explanation, working at your own level. This will give an indication of your progress with the subject knowledge audit. Throughout, identify websites and reference materials used In your reflection note key learning points and any areas for future study.
