Further practice
1) Circle the group with the greater number of things.
By seeing the picture kids can easily find out the greater number of groups.
lets teach them how to check it out.
first count and write the number of circles in each group
we have 9 circles in one group and 7 circles in another group.
In counting number , 7 comes first then 9 comes.
(counting number always be in increasing order)
Hence a group which has 9 circles is the greater number of circles.
2) Which number is bigger?
a) 11 or 5
Counting number, 5 comes first then 11 comes.
Hence 11 is the bigger number.
b) 19 or 16
Counting number, 16 comes first then 19 comes.
Hence 19 is the bigger number.
3) Look at the box of pencils.
Can 18 children each have a pencil?
Write YES or NO. Explain Why?
1 Child ---- 1 pencil
2 Children ---- 2 pencils
3 Children ---- 3 pencils
18 Children ---- 18 pencils
( if we have 18 children atleast we need 18 pencils )
We have 18 Children, if each children can have 1 pencil we need 18 pencils.
In our Pencil box we have 20 pencils
20 Pencils > 18 children
which means 18 children can have 1 pencil and 2 pencils left.
Yes 18 children each can have a pencil.
Number of pencils is greater than the number of children.
4) look at this number track.
10 11 12 13 14 15 16 17 18 19 20
Write a number that is smaller than 16 but greater than 13
Method 1
first lets mark smaller than 16 (which means counting order-backwards from 16)
10 11 12 13 14 15 16 17 18 19 20
now lets mark greater than 13
10 11 12 13 14 15 16 17 18 19 20
now,
10 11 12 13 14 15 16 17 18 19 20
10 11 12 13 14 15 16 17 18 19 20
14 and 15 are common in both
hence 14 and 15 are the numbers that are smaller than 16 but greater than 13
Method 2
Smaller than 16 : 15 14 13 12 11 10
Greater than 13 : 14 15 16 17 18 19 20
now we have to check the common numbers present in both
Smaller than 16 : 15 14 13 12 11 10
Greater than 13 : 14 15 16 17 18 19 20
hence 14 and 15 are the numbers that are smaller than 16 but greater than 13
Method 3
Smaller than 16 but greater than 13
we have to list the numbers greater than 16 and stops before 13 (because Smaller than 16 but greater than 13)
15,14
hence 14 and 15 are the numbers that are smaller than 16 but greater than 13
5) Count the number of fruit.
Strawberries : 16
Oranges : 20
Pears : 17
Fill in the blanks with strawberries, oranges or pears.
a) The number of __________ is the greatest
lets take the numbers alone
16,20 and 17
here 20 is the biggest number since it comes last in counting numbers
Oranges - 20
hence The number of Oranges (20) is the greatest
b) The number of ___________ is the smallest
lets take the numbers alone
16,20 and 17
here 16 is the smallest number since it comes first in counting numbers
Strawberries - 16
hence The number of Strawberries (16) is the smallest
6) Fill in the missing numbers.
a) 1 less than 9 is 8 (given 1 less than, so we have to go one step backward )
b) 2 more than 11 is 13 ( given 2 more than, so we have to go two steps ahead )
c) 12 is 2 less than 14 ( given 2 less than, so we have to go two steps backward from 14 )
d) 19 is 1 more than 18 ( given 1 more than, so we have to go one step
ahead from 18 )
e) 22 is 10 more than 12 (22 is greater than 12 so its more and from 22 to reach 12 , it takes ten steps)
f) 6 is 10 less than 16 (6 is smaller than 16 so its less and from 6 to reach 16, it takes ten steps)
7) There are 19 cherries in a basket. Rita puts 1 more cherry into the basket. How many cherries are there in the basket now?
19 cherries are there. Rita puts one more candy to that.
ONE MORE which means leave a finger and count ahead
that is 20.
hence there are 20 cherries now
8) a) Write a number between 6 and 12
To find the between numbers,
in counting order, start next to 6 and stops before 12
so, 7 , 8 , 9 , 10 , 11 are the numbers between 6 and 12
7 is one of a number between 6 and 12
b) Write a number between 11 and 19
To find the between numbers,
in counting order, start next to 11 and stops before 19
so, 12 , 13 , 14 , 15 , 16 , 17 , 18 are the numbers between 11 and 19
14 is one of a number between 11 and 19
9) Tom, Rita and Ari play a computer game.
Tom : My score is 17 points
Rita : My Score is 2 less than Ari's
Ari : My score is one more than Tom's
Write the scores in order.
Begin with the largest ______ , _____ , ______
we know Tom's score = 17 points
To find Rita's Score we need to find Ari's score first.
Ari's score is one more than Tom's
that is move ahead one step from 17(Tom's score)
Ari's score = 18
Rita's score is 2 less than Ari's
that is move backward two steps from 18 (Ari's score)
Rita score = 16
17,18,16 are the score of Tom , Ari , Rita
Lets write in order (with biggest)
18 , 17 , 16
10) Look at this pattern.
Draw what comes next and write the number.
first they have given 8 circles.
if we cancel out 2 circles we will get the next pattern 6
similarly if we cancel out 2 circles again we will get the next pattern 4
to get the next pattern we have to cancel out 2 more circles which gives 2
11) Write the missing numbers in these patterns.
a) 15 , 16 , 17 , 18 , 19 , 20 ( 1 more , count ahead )
b) 9 , 11 , 13 , 15 , 17 , 19 ( 2 more , count ahead )
c) 10 , 8 , 6 , 4 , 2 , 0 ( 2 less , count back )
d) 10 , 9 , 8 , 7 , 6 , 5 ( 1 less , count back )
12) Tom has some stickers.
The number of stickers is between 13 and 18.
What is the greatest number of stickers that Tom can have?
First we have to find the numbers between 13 and 18
lets list numbers from 13 to 18
13 14 15 16 17 18
numbers between 13 and 18 = 14 , 15 , 16 , 17
here the greatest number is 17
hence Tom can have 17 number of stickers
13) Put these numbers in order. Begin with the smallest.
17 , 0 , 8 , 2 , 11 , 9
Counting number order which goes like 1,2,3,4,5...
here we have 0. 0 which means nothing.
with 0 if we add 1 more we will get 1.
So 0 comes before 1 that is,
0,1,2,3,4,5...
now lets write with the smallest
0 , 2 , 8 , 9 , 11 , 17
1) Circle the group with the greater number of things.
By seeing the picture kids can easily find out the greater number of groups.
lets teach them how to check it out.
first count and write the number of circles in each group
we have 9 circles in one group and 7 circles in another group.
In counting number , 7 comes first then 9 comes.
(counting number always be in increasing order)
Hence a group which has 9 circles is the greater number of circles.
2) Which number is bigger?
a) 11 or 5
Counting number, 5 comes first then 11 comes.
Hence 11 is the bigger number.
b) 19 or 16
Counting number, 16 comes first then 19 comes.
Hence 19 is the bigger number.
3) Look at the box of pencils.
Can 18 children each have a pencil?
Write YES or NO. Explain Why?
1 Child ---- 1 pencil
2 Children ---- 2 pencils
3 Children ---- 3 pencils
18 Children ---- 18 pencils
( if we have 18 children atleast we need 18 pencils )
We have 18 Children, if each children can have 1 pencil we need 18 pencils.
In our Pencil box we have 20 pencils
20 Pencils > 18 children
which means 18 children can have 1 pencil and 2 pencils left.
Yes 18 children each can have a pencil.
Number of pencils is greater than the number of children.
4) look at this number track.
10 11 12 13 14 15 16 17 18 19 20
Write a number that is smaller than 16 but greater than 13
Method 1
first lets mark smaller than 16 (which means counting order-backwards from 16)
10 11 12 13 14 15 16 17 18 19 20
now lets mark greater than 13
10 11 12 13 14 15 16 17 18 19 20
now,
10 11 12 13 14 15 16 17 18 19 20
10 11 12 13 14 15 16 17 18 19 20
14 and 15 are common in both
hence 14 and 15 are the numbers that are smaller than 16 but greater than 13
Method 2
Smaller than 16 : 15 14 13 12 11 10
Greater than 13 : 14 15 16 17 18 19 20
now we have to check the common numbers present in both
Smaller than 16 : 15 14 13 12 11 10
Greater than 13 : 14 15 16 17 18 19 20
hence 14 and 15 are the numbers that are smaller than 16 but greater than 13
Method 3
Smaller than 16 but greater than 13
we have to list the numbers greater than 16 and stops before 13 (because Smaller than 16 but greater than 13)
15,14
hence 14 and 15 are the numbers that are smaller than 16 but greater than 13
5) Count the number of fruit.
Strawberries : 16
Oranges : 20
Pears : 17
Fill in the blanks with strawberries, oranges or pears.
a) The number of __________ is the greatest
lets take the numbers alone
16,20 and 17
here 20 is the biggest number since it comes last in counting numbers
Oranges - 20
hence The number of Oranges (20) is the greatest
b) The number of ___________ is the smallest
lets take the numbers alone
16,20 and 17
here 16 is the smallest number since it comes first in counting numbers
Strawberries - 16
hence The number of Strawberries (16) is the smallest
6) Fill in the missing numbers.
a) 1 less than 9 is 8 (given 1 less than, so we have to go one step backward )
b) 2 more than 11 is 13 ( given 2 more than, so we have to go two steps ahead )
c) 12 is 2 less than 14 ( given 2 less than, so we have to go two steps backward from 14 )
d) 19 is 1 more than 18 ( given 1 more than, so we have to go one step
ahead from 18 )
e) 22 is 10 more than 12 (22 is greater than 12 so its more and from 22 to reach 12 , it takes ten steps)
f) 6 is 10 less than 16 (6 is smaller than 16 so its less and from 6 to reach 16, it takes ten steps)
7) There are 19 cherries in a basket. Rita puts 1 more cherry into the basket. How many cherries are there in the basket now?
19 cherries are there. Rita puts one more candy to that.
ONE MORE which means leave a finger and count ahead
that is 20.
hence there are 20 cherries now
8) a) Write a number between 6 and 12
To find the between numbers,
in counting order, start next to 6 and stops before 12
so, 7 , 8 , 9 , 10 , 11 are the numbers between 6 and 12
7 is one of a number between 6 and 12
b) Write a number between 11 and 19
To find the between numbers,
in counting order, start next to 11 and stops before 19
so, 12 , 13 , 14 , 15 , 16 , 17 , 18 are the numbers between 11 and 19
14 is one of a number between 11 and 19
9) Tom, Rita and Ari play a computer game.
Tom : My score is 17 points
Rita : My Score is 2 less than Ari's
Ari : My score is one more than Tom's
Write the scores in order.
Begin with the largest ______ , _____ , ______
we know Tom's score = 17 points
To find Rita's Score we need to find Ari's score first.
Ari's score is one more than Tom's
that is move ahead one step from 17(Tom's score)
Ari's score = 18
Rita's score is 2 less than Ari's
that is move backward two steps from 18 (Ari's score)
Rita score = 16
17,18,16 are the score of Tom , Ari , Rita
Lets write in order (with biggest)
18 , 17 , 16
10) Look at this pattern.
Draw what comes next and write the number.
first they have given 8 circles.
if we cancel out 2 circles we will get the next pattern 6
similarly if we cancel out 2 circles again we will get the next pattern 4
to get the next pattern we have to cancel out 2 more circles which gives 2
11) Write the missing numbers in these patterns.
a) 15 , 16 , 17 , 18 , 19 , 20 ( 1 more , count ahead )
b) 9 , 11 , 13 , 15 , 17 , 19 ( 2 more , count ahead )
c) 10 , 8 , 6 , 4 , 2 , 0 ( 2 less , count back )
d) 10 , 9 , 8 , 7 , 6 , 5 ( 1 less , count back )
12) Tom has some stickers.
The number of stickers is between 13 and 18.
What is the greatest number of stickers that Tom can have?
First we have to find the numbers between 13 and 18
lets list numbers from 13 to 18
13 14 15 16 17 18
numbers between 13 and 18 = 14 , 15 , 16 , 17
here the greatest number is 17
hence Tom can have 17 number of stickers
13) Put these numbers in order. Begin with the smallest.
17 , 0 , 8 , 2 , 11 , 9
Counting number order which goes like 1,2,3,4,5...
here we have 0. 0 which means nothing.
with 0 if we add 1 more we will get 1.
So 0 comes before 1 that is,
0,1,2,3,4,5...
now lets write with the smallest
0 , 2 , 8 , 9 , 11 , 17
