10 2-D Shapes

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

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

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

14 3-D means the shape has 3 dimensions; length, width and depth. 3-D Shapes

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

40 Polygon Land Now, lets 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.

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

42 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.

43 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?

44 You made it. Hip, Hip, Hooray!

45 Just kidding, this is it ! The End. Click here of you want to take the quiz once more
