# Which number is greater?

1. The pictures have ten-sticks and one-dots. Fill in the missing parts.
Then circle the number that is more.

 a. OR 3   tens   6   ones    36 ____ tens ____ ones ______
 b. OR 54 ______
 c. OR ____ tens ____ ones ________ ____tens ____ ones ______
 d. OR ______ ______

Study the above pictures. Do we first check how many TENS the numbers have or
how many ONES the numbers have?

• Check first how many ____________ the numbers have.

• If the numbers have the same amount of _________, then compare the __________.

For example,

• 92 has more TENS than 89, so 92 is greater than 89.

• 62 has the same amount of TENS as 66, but it has less ONES than 66.
Therefore 62 is less than 66.

The symbol  >  means “greater than”, and  <  means “less than”.
The open end or open “mouth” of the symbol ALWAYS points to the bigger number.

 For example: 3 < 5 14 > 3 60 > 50 48 < 99 7 < 17

2. Write <  or  >  between the numbers. You can draw ten-sticks and one-dots to help.

 a.  45 54
 b.  34 24
 c.  50 54

 d.  15 56
 e.  29 64
 f.  81 90
 g.  77 47
 h.  34 94
 i.  80 68

3. Write <  or  > between the numbers to compare them. Number line can help.

a.

 81 < 88

b.

 95 59
c.
 99 96
d.
 85 91

e.
 90 88

f.

 49 94
g.
 90 99
h.
 100 87

i.
 50 55

j.

 22 12
k.
 98 89
l.
 24 42

4. Write  < , >  or  = .

a.

 80 + 2 < 80 + 7

b.

 10 + 7 70 + 5

c.
 60 + 5 40 + 5
d.
 50 + 7 70 + 3

e.
 6 + 60 6 + 80

f.

 5 + 40 40 + 5

g.
 40 + 5 40 + 4

h.

 70 + 5 5 + 70

5. Put the numbers in order from the smallest to the largest.

 a.  68,  67,  46 _____ <  _____ <  _____ b.  33,  53,  37 _____ <  _____ <  _____ c.  48,  46,  18 _____ <  _____ <  _____ d.  87,  78,  80 _____ <  _____ <  _____ e.  48,  84, 46,  50 _____ <  _____ <  _____ <  _____ f.  98,  87,  67,  76_____ <  _____ <  _____ <  _____

 Who am I? I have two more tens than 40, and  the same amount of ones as 17.
