Which number-set is arranged in order, beginning with the largest number? (c)
ODD NUMBER
Numbers ending with 1, 3, 5, 7, 9
Example
19 , 23, 835, 47, 1259, 361
EVEN NUMBER
Numbers ending with 0, 2, 4, 6, 8
ORDERING
Example
Arrange the
following in decreasing order (big to small)
23 642, 22
893, 25147
Method
Step1: Arrange numbers
in rows
2 2 6 4 2
2 3 6 9 3
2 5 1 4 7
Step 2: Compare from left to right, until the column with different values, label from big (1) to small
2 3 6 4 2 (2)
2 2 8 9 3 (3)
2 5 1 4 7 (1)
same ↑ go next right number
↑ 5 is
the largest number(1), then 3(2) , 2(1) <- label (1), (2) ,(3)
Step3:
Write the answer with label (1), (2), (3)
25147, 23693, 22642
Example
Arrange the
following in increasing order (small to big)
43642, 43193, 54147
Method
Step1: Arrange numbers
in rows
4 3 6 4 2
4 3 1 9 3
5 4 1 4 7
Step 2: Compare from left to right, until the column with different values, label 3 (for 3 numbers comparison) for the largest number, and continue to next column
4 3 6 4 2 2
4 3 1 9 3 1
5 4 1 4 7 3
^ 5 is biggest, strike, label 3(3 numbers), go next right number
^ both are 3, go next right number
^
6 and 1, label 2 for the bigger number, and 1 for the smaller number
Step3:
Write the answer - label 1, 2, 3

Solving 'More than' and 'Less than' questions
More than question (big - small) Method
=> Big number - small number
Example: 102 is ______ more than 77.
Step1: Circle/Underline 102, 77, More than (-) => [big - small]
Step2: Write in equal form
=> 102 - 77 = ___ [Arrange big number - small number = _____ ]
102 - 77 = 25
Step3: Solve
102 is 25 more than 77.
Example: 523 is 100 more than ____
Step 1 : Circle/Underline 523, 100, More than => [big - small]
Step 2 Write in equal form
=> 523 - 100 = ____ [Arrange big number - small number = _____ ]
523 - 100 = 423
Step 3 : Solve
523 is 100 more than 423
Less than questions
(1) The first number is smaller than the second numberFirst number is smaller than the second number, big number subtract(-) the small number
First number smaller : big number - small number
Example
68 is ______ less than 89.
Step1: Circle/Underline 68(1st), 89(2nd) , Less than => 1st number(68) is smaller (-)
Step 2: Write in equal form (big number - small number)
89 - 68 = _____
=> 89 - 68 = 21
Step 3: Solve
68 is 21 less than 89
(2) The first number is bigger than the second number
If the first number is bigger than the second number, ADD + both numbers
First number bigger : big number + small number
Example: 523 is 100 less than ____
Step 1 : Circle/Underline 523(1st), 100 (2nd), less than: 1st number bigger (+)
Step 2 : Write in equal form
523 + 100 = _____ (Add both numbers)
523 + 100 = 623
Step 3 : Solve
523 is 100 less than 623
Example (more than / Less than)
Eric has 5 yellow balls. Rahul has 3 blue stickers.
(a) How many more sticker does Eric have?
Step 1: Underline, (method - more than => - )
Step 2: Write in equal form
5 - 3 = 2
Step 3: Solve
Eric has 2 more stickers than Bala
(b) How many stickers must Rahul has to have the same number of sticker as Eric?
Step 1: Underline and method to use
[Rahul has less sticker than Eric ]
3 is ___ less than 5 [1st number is smaller, big - smallStep 2 : Write in equal form
5 - 3 =.
5 - 3 = 2
Step 3 : Solve
Rahul has 2 fewer than Eric
