18. 10 x 10 = 100 a hundred ©

19. 10 x 10 = 100 a hundred = 10 2 ten to the two ©

20. This is called an array ©

21. Now let’s count arrays

32. So how many Cubes altogether? ©

33. 10

34. 1000 cubes

35. 10x10x10 = 1000 a thousand ©

36. 10x10x10 = 1000 a thousand = 10 3 ten to the three ©

37. 10x10x10 = 1000 Fill in your TABLE = 10 3 ten cubed ©

38. Now how about? ©

39. 10

40. 10x10

41. 10x10x10

42. 10x10x10x10 = ?

43. 10x10x10x10 = 10,000 ten thousand

44. 10x10x10x10 = 10,000 ten thousand = 10 4 ten to the four ©

46. ©

47. and take 1000 of these ©

49. If every green box contains 1000 red ones

50. Every box contains 1000 little boxes so 1,000,000 all together 10x10x10x10x10x10

51. Every box contains 1000 little boxes so 1,000,000 all together 10x10x10x10x10x10 = 1000 x 1000

52. Every box contains 1000 little boxes so 1,000,000 all together 10x10x10x10x10x10 = 1000 x 1000 =1,000,000 =10 6 ©

53. What about a billion ©

54. 10x10x10 x10x10x10x10x10x10 = 1,000,000,000 =10 9 a billion ©

55. If you think that’s a big number how about

57. 10000000000000000000000 ©

58. with 22 noughts or zeros ©

59. 10 22 ©

60. You swallow 10 22 molecules of air every time you breathe in ©

61. If you think that’s a big number how about

62. 0000000000 0000000000 0000000000 0000000000 0000000000 © 100 zeros 1
