  1. 2/5 = 1/10 = ¾ = ¼ = 6/10= 4/5 = 2/20 = 2/4 =

  2. 10% 25% 7% 30% 74% 5% 20% 75% 40% 80%

  3. LO To recognise types of triangles

  4. EQUILATERAL TRIANGLE All 3 Sides are equal in Length All 3 interior angles are the same

  5. ISOSCELES TRIANGLE Two Sides of equal Length Two interior angles are the same

  6. SCALENE TRIANGLE No Sides of equal Length All interior angles are different

  7. RIGHT ANGLED Right-Angled Triangles can be either Isosceles or scalene triangles How many degrees are the other two interior angles in a right angled isosceles? They have an Interior angle of 90 degrees Scalene Right Angled Triangle Isosceles Right Angled Triangle

  8. SHOW ME.. Using a piece of elastic show me the following triangles

  9. DRAW ME.. Using your mini whiteboards draw me the following triangles…

  10. EXTENSION! c x a b Draw a triangle and extend one line like above. Mark your angles a, b, c and x. Measure all the angles. Repeat with a different triangle Can you write a rule?

  11. Convert fractions to decimals.

  12. 2/5 = 1/10 = ¾ = ¼ = 6/10= 4/5 = 2/20 = 2/4 =

  13. 0.10 0.25 0.63 0.3 0.4 0.5 0.20 0.75 0.40 8.7

  14. LO To identify and know the properties of various quadrilaterals.

  15. PARALLEL • These type of lines stay the same distance apart for their whole length. They do not need to be the same length

  16. PERPENDICULAR • A line is perpendicular to another line if they meet at 90 degrees.

  17. POLYGONS Two-dimensional shapes that have sides made from straight lines. • E.g. triangles squares hexagons

  18. B . A . . D . C QUADRILATERALS 4 vertices 4 sides 4 angles

  19. B . A . B . A . . D . . D C The sum of ALL the angles of a quadrilateral is 360o . C QUADRILATERALS 360o

  20. QUADRILATERALS • The sum of all the angles equals 360º degrees. 90º 90º 90º 90º

  21. WHAT’s THE MISSING ANGLE? 70º 70º 70º 70º 110º ? 110º ? + 360º

  22. WHAT’s THE MISSING ANGLE? 65º ? 65º 65 115º 65º 115º ? 360º

  23. TRAPEZIUM Discuss the properties of a trapezium with your partner.

  24. TRAPEZIUM One pair of opposite sides are parallel

  25. PARALLELOGRAM Draw a parallelogram and try to find as many of its properties as you can.

  26. PARALLELOGRAM • Opposite sides are equal • Opposite sides are parallel • Opposite angles are equal

  27. RHOMBUS Discuss the properties of the rhombus with your partner

  28. RHOMBUS All sides are equal Opposite sides are parallel Opposite angles are equal

  29. RECTANGLE How many properties belonging to the rectangle can you find?

  30. RECTANGLE Opposite sides are equal Opposite sides are parallel All angles are right angles (90o)

  31. SQUARE Discuss the properties of the square with your partner

  32. SQUARE All sides are equal Opposite sides are parallel All angles are right angles (90o)

  33. NAME THE QUADRILATERAL 1 3 2 irregular rhombus rectangle 5 6 4 parallelogram trapezium square

  34. Learning Objective Convert larger to smaller units of length and vice versa: m to km; cm or mm to m. Joanne Smithies Our Lady & St. Gerards RCP

  35. We use different metric units to measure :- Distance Capacity Weight We can use our knowledge of multiplying and dividing by 10, 100 or 1000 to change or convert measurements in one unit to measurements in another unit.

  36. We are going to use our knowledge about multiplying and dividing by 100 to convert centimetres to metres and to convert metres to centimetres.

  37. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  38. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  39. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  40. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  41. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  42. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  43. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  44. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  45. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  46. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  47. There are 100 centimetres in 1 metre When we change from cm to m we divide by:- 100 Remember! When we divide by 100 the units move two places to the right. This is how we change 427cm into metres:- ÷100

  48. Therefore:- 427cm = 4.27m cm m ÷100 ÷100 ÷100

  49. Convert from centimetres to metres 354cm 15.4cm 779cm 52.4cm 939cm 395cm 25.8cm 3.54m 0.154m 7.79m 0.524m 9.39m 3.95m 0.258m ÷100

  50. To change from metres to centimetres we MULTIPLY BY 100. REMEMBER When we multiply by 100 we move each digit two places to the left:- 3.51m =
