Math KG : Worksheet 5 : Subtracting numbers by counting back

1 Fill in the blanks 

a) 6 - 1 = _________

Step 1

Check whether its + or -

here its -

Step 2 

find the smallest number

here the smallest is 1

leave one finger

Step 3 

now lets look for the another number which is 6 here

since its - we have to count back

we left one finger : already we are having 6 - count backwards which is 5

hence  6 - 1 = 5

b) 5 - 4 = ________

Step 1

Check whether its + or -

here its -

Step 2 

find the smallest number

here the smallest is 4

lets leave four fingers

Step 3 

now lets look for the another number which is 5 here

since its - we have to count back

we left four fingers : already we are having 5 - count backwards

first finger goes with 4
second finger goes with 3
third finger goes with 2
fourth finger goes with 1

hence  5 - 4 = 1

2 Write the subtraction sentences in the boxes provided. Then fill in the blanks.

a) what is the differences between 10 and 6?

Differences which means we have to do subtraction

so  the subtraction sentence is 10 - 6 = ____

now lets find 10-6 = ?

Method 1

we can use number tracks to find the differences

first in the number track, mark 10 and 6

now lets check to reach 6 from 10 how many steps we have to move

hence 10 - 6 = 4

Method 2

Step 1

Check whether its + or -

here its -

Step 2 

find the smallest number

here the smallest is 6

lets leave six fingers

Step 3 

now lets look for the another number which is 10 here

since its - we have to count back

we left four fingers : already we are having 10 - count backwards 

first finger goes with 9
second finger goes with 8
third finger goes with 7
fourth finger goes with 6
fifth finger goes with 5
sixth finger goes with 4

hence  10-6 = 4

Math KG : Addition and subtraction : Worksheet 3

5. Fill in the missing numbers


a)

Step 1

we have to make the numbers inside the dotted box to be 10

so,

Step 2

Inside the dotted box, we have 7 and we need to find another number
Both together should make 10

to reach 10 from 7 lets see how many steps we have to move forward

so 7 + 3 = 10

Step 3

now we should check what number if we add with 3 will get 9
that is, to reach 9 from 3 lets see how many steps we have to move forward

so 3 + 6 = 9
hence 

9 + 7 = 16
6 + 10 = 16

d)

Step 1


we have to make the numbers inside one of the dotted box to be 10

Step 2

Inside the dotted box, we have 2 and we need to find another number
Both together should make 10


to reach 10 from 2 lets see how many steps we have to move forward

so 2 + 8 = 10

Step 3

now we should check what number if we add with 8 will get 9

that is, to reach 9 from 8 lets see how many steps we have to move forward

8 + 1 = 9

Step 4

now, 4 and 1 together make 5 that is 4 +1=5

hence 2 + 9 + 4 = 15
also 10 + 5 = 15

Math KG : Adding numbers by using number pairs

Addition

Addition is bringing two or more numbers(or objects) together to make a new total

Example

Jim has 2 candies and Tim has 5 candies

both together has 2 + 5 which is 7 candies in total

we are having many methods to teach addition to the kids

Method 1 ( Using fingers )

Number of candies Jim has = 2
Number of candies Tim has = 5

2 is the smallest number , so leave two fingers

one finger goes with 6 and second finger goes with 7 ( since we are adding we have to move forward from 5)

hence total candies = 7

Method 2 (Using Number tracks)

Number of candies Jim has = 2
Number of candies Tim has = 5

here the number track

1 2 3 4 5 6 7 8 9 10 11

lets start with Jim who has 2 candies, so lets mark on 2

1 2 3 4 5 6 7 8 9 10 11

now lets go to Tim who has 5 candies, so lets move 5 steps forward

1 2 3 4 5 6 7 8 9 10 11

we reached on 7.

Hence total candies = 7

Making 10

Example : 7 + 6

lets consider, we have 7 RED candies and 6 GREEN candies

0 0 0 0 0 0 0 0 0 0 0 0 0

now lets place 10 black candies below this

0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0

to match this black candies with the above row, 

0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0

so we can write this 7 + 6 = 7 + 3 + 3 = 10 + 3

Question 1

here we go,

first we make the dotted box into 10, that is

now we have to reach 10 from 5

so to reach 10 from 5 we need 5 more steps ahead

now lets fill the last circle. here we have to reach 11 from 5

so to reach 11 from 5 we need 6 more steps ahead

11 + 5 = 16
6 + 10 =16

Math KG : Symmetry

Symmetry

Symmetry is when one shape becomes exactly like another if you flip , slide or turn it. That is symmetry is Reflection or a mirror image.

Line of Symmetry


Line of Symmetry is the imaginary line where we could fold the image and have both halves match exactly. 

Those are some examples of Symmetry and those lines are line of symmetry.










Non Symmetry

 Those are some Non Symmetrical shapes
