COUNTING, READING AND WRITING OF NUMBERS 51 – 100

Back to: Mathematics Primary 1

Hello children, welcome back to class

 

In the previous lessons we learnt how to count and write numbers 1 – 50. Let’s refresh our memories by writing 1 – 50 in the table below

Copy and Complete the Table Below

 

		3							10
				15			18
	22					27
31								39
			44		46

 

We can also write 51 – 100 in the same way.

51 is written 5 and 1. The next will be 5 and 2, then 5 and 3 and so on.

Let’s try it

51  is  5 and 1

52 is  5 and  2

53 is  5 and 3 and so

 

ACTIVITY

• Complete 54 – 59
• After 59 you have 60
• Complete the table below by removing 1, 2, 3 etc

 

60

61

69

 

 

70

79

 

 

80

89

 

 

90

99

100

 

After 69(6 and 9) you have 70(7 and 0). So, after 99(9 and 9) we will have 100(10 and 0)
