  9. 2-D Shapes

  10. 2-D Shapes Right-angled triangle Isosceles triangle Scalene triangle No equal sides No equal angles One of its angles is a right angle (90°) 2 equal sides 2 equal angles Equilateral triangle 3 equal sides 3 equal angles of 60°

  11. More 2-D Shapes Pentagon Hexagon 5 sides. have 6 sides Circle No sides No angles

  12. More 2-D Shapes Square Trapezoid Square 4 equal sides 4 right angles Kite 2 pairs of equal No parallel sides. One pair of parallel sides of different lengths Rhombus Rectangle Rhombus Rectangle Parallelogram 2 pairs of equal sides 4 right angles 2 pairs of equal sides Opposite sides are parallel Opposite angles are equal 4 equal sides Opposite sides are parallel Opposite angles are equal

  13. 3-D Shapes 3-D means the shape has 3 dimensions; length, width and depth.

  14. 3-D Shapes Sphere Cylinder Cone Long tube with 2 equal sized circular ends. Every point on the surface of the sphere is the same distance from the centre. A pyramid with a circular cross section. The point of the cone is directly above the centre of the circular base.

  15. 3-D Shapes Six faces which are all rectangles Faces 6 Corners 8 Edges 12 Six faces which are all squares Faces 6 Corners 8 Edges 12

  39. Polygon Land • Now, let’s have some fun at polygon Land. • You'll find hundreds of polygons to drag anywhere you want. • Be a creative designer at polygon Land. These are examples of what you can do there. Be sure to read the instructions before you play. Ready? Click here.

  40. Class Activity Find more about 3-D shapes with your partner. Click on the shapes below and print them then follow the instructions on the sheet.

  41. With a partner, make a chart like the one below and use it to find 3-D shapes around the classroom. Answer each question about the properties of the object and then see if you can correctly identify and name the object.

  42. Homework • Choose a 3D shape and design a promotion poster for it. What makes this shape special? What are its properties? What is it used for/where is it seen (for example, packaging, buildings) and what makes it a good shape for this use?

  43. You made it. Hip, Hip, Hooray!
