Math KG : Number patterns : Worksheet 4

Question 1

Look at the patterns shown below. Then fill in the blanks.

This number pattern starts with _________
To find the next number in this pattern, we count on in ___________

In the above picture the pattern starts with 2

• first we have to check whether the patterns gets increases or decreases.
• Next we have to find the common interval.

here, the patterns gets INCREASES
And the patterns gets increases by 1. that is to get the next pattern we have to add one more circle.

2,3,4,5 with 5 if we add one more circle we will get 6
with 6 if we add one more circle we will get 7 and goes on

so the patterns goes by 2,3,4,5,6,7...

Hence to find the next number in this pattern, we count on in ones

This number patterns starts with __________
To find the next number in this pattern, we count _________ in _________

In the above picture, the pattern starts with 8

here, the patterns gets decreasing.
to get the next pattern we have to cross out two circles
 from 8 circles if we cross out 2 circles, we will get 6
from 6 circles if we cross out 2 circles we will get 4
similarly to get the next pattern we have to cross out 2 circles from 4
so we will get 2
hence the patterns be 8,6,4,2...

To find the next number in this pattern, we count back in twos

Question 2

Look at these patterns 
Draw what comes next and write the number.

In the above pic, the pattern gets increasing
in each row, the pattern gets increases by 2. that is we have to add 2 more 'x' to get the next pattern
the pattern starts with 2. 
with this if we add 2 more 'x' we will get 4
add 2 more with 4 to get next pattern which is 6
add 2 more with 6 to get next pattern which is 8
add 2 more with 8 to get the next pattern which is 10

In the above pic, the pattern gets decreasing
in each row, the pattern gets decreases by 1. that is we have to cancel out 1 circle to get the next pattern
the pattern starts with 8. 
with this if we cancel out 1 circle, we will get 7
cancel out 1 circle to get the next pattern, we will get 6
with this cancel out 1 circle to get the next pattern, we will get 5
with this cancel out 1 circle to get the next pattern, we will get 4

Question 3

Look at the number patterns. Then fill in the blanks.

a) 1 , 11 , _____ , 31 , 41 , 51

This number patterns starts with __________
To find the next number in this pattern, we count _________ in _________

here, the numbers gets increasing

first given number is 1, to reach the next number 11 we have to count on in 10's.

so from 11 if we count on in 10's we will get 21.

hence the pattern goes like 1 , 11 , 21 , 31 , 41 , 51

This number patterns starts with 1

To find the next number in this pattern, we count ON in 10's

b) 50 , 40 , ____ , 20 , _____ , _____

This number patterns starts with __________

To find the next number in this pattern, we count _________ in _________


here, the numbers gets decreasing

first given number is 50, to reach the next number 40 we have to count back in 10's.

so from 40 if we count back in 10's we will get 30.
from 30, if we count back in 10's we will get 20(given)
from 20, if we count back in 10's we will get 10
from 10, if we count back in 10's we will get 0

hence the pattern goes like 50 , 40 , 30 , 20 , 10 , 0

This number patterns starts with 50


To find the next number in this pattern, we count back in 10's

c) 23 , ____ , 43 , _____ , 63 , 73

This number patterns starts with __________


To find the next number in this pattern, we count _________ in _________

here, the numbers gets increasing

given, first number = 23
we have to find the next number. 
also given third number = 43
5th and 6th number = 63 and 73 respectively.
with the last 2 numbers, to reach 73 from 63 we count on in 10's.

so from 23 if we count on in 10's we will get 33
from 33 if we count on in 10's we will get 43(given)
from 43 if we count on in 10's we will get 53

hence the pattern goes like 23 , 33 , 43 , 53 , 63 , 73

This number patterns starts with 23


To find the next number in this pattern, we count ON in 10's

Question 4

Ari describes his number pattern.

"I Start with 14
Then I count on in twos"

Write the first four numbers in this number pattern.

Since Ari described that his pattern starts with 14
The first number be 14

Also Ari said that he count ON in TWOS

which means the numbers gets increasing that is we have to move ahead two steps

Hence the pattern be 14 , 16 , 18 , 20

Question 5

Rita describes her number pattern.

"I Start with 11
Then I count back in ones"

Write the first four numbers in this number pattern.

Since Rita described that her pattern starts with 11

The first number be 11

Also Rita said that she count back in ONES


which means the numbers gets decreasing that is we have to move one step back.

Hence the pattern be 11 , 10 , 9 , 8

Question 6

a) 7 , 8 , 9 , 10 , 11 (increases,Ones)

b) 10 ,12 , 14 , 16 , 18 (increases,twos)

c) 19 , 18 , 17 , 16 , 15 (decreases,ones)

d) 9 , 7 , 5 , 3 , 1 (decreases,twos)

e) 11 , 12 , 13 , 14 , 15 , 16 (increases,Ones)

f) 40 , 30 , 20 , 10 , 0 (decreases,tens)
