Lesson- Operation on Whole numbers ( Multiplication and
Division)
Multiplication of Large Numbers( Write terms and properties in c.w copy)
As we know, multiplication is the short way to do repeated addition.
Multiplier- The number by which any number is multiplied. Multiplicand -The number to be multiplied . Product - The result of the multiplication.
Example 1. Multiply 76432 by 5245. Solution.
Properties of multiplication: 1. Closure property:
For any two whole numbers a and b,their product ax b is always a whole number. E.g. 12 x 7 = 84, 12, 7 and 84 all are whole numbers. 2. Commutative property:
For any two whole numbers a and b, a x b = b x a ,Order of multiplication is not important. E.g 11 x 6 = 66 and 6 x 11 = 66 Therefore, 11 x 6 = 6 x 11
3. Associative property:
For any three whole numbers a, b and c, (a x b) x c = a x (b x c), this means the product is regardless of how grouping is done. E.g 8 x (4 x 5) = 8 x 20 = 160; (8 x 4) x 5 = 32 x 5 = 160 Therefore, 8 x (4 x 5) = (8 x 4) x 5
4. Multiplicative identity:
For any whole number a, a x 1 = a
Since any number multiplied by 1 doesn’t change its identity
hence 1 is called as multiplicative identity of a whole number. E.g. 21 x 1 = 21
5. Multiplication by zero:
For any whole number a, a x 0 = 0, E.g 25 x 0 = 0
6. Distributive property of multiplication over Addition and subtraction
For example: (i) (18+ 15) × 5 = 18 × 5 + 15 × 5
(ii) (18 – 15) × 5= 18 × 5 – 15 × 5 (iii) 172 x 97 =172 x (100-3) {as 97=100-3} = 172 x 100 - 172 x 3 = 17200 - 516= 16684 Rules for the multiplication by 10, 100 and 1000:And their multiples
*To multiply a number by 10, 100, or 1000 we need to count the number of zeroes in the multiplier and multiplicand and write the same number of zeroes to
the right of the product. For example: (i) 750× 10 = 7500 (ii) 234 × 100 = 23400 (iii) 1692 × 10000 = 16920000
*To multiply a number by 2000, 3000 or 4000 and so on, we multiply the number by the digit in the thousands place of the multiplier and write the three zeros on the right of the product. For example: (i) 735 × 6000 = (735 × 6) × 1000
= (4410) × 1000 = 4410000
Multiplication by rearranging By rearranging the order of the numbers,
multiplication becomes easy. We try to combine the numbers that produce maximum number of zeros after the multiplication. Remember- 2 x5=10 25 x 4 =100 20 x 5 = 100 50 x 2 = 100
125 x 8 = 1000 Ex- 25 x 4581x 4= 4581x(25x4) =4581 x 100= 458100
Division of Large Numbers We already know about division as repeated subtraction, equal sharing and inverse of multiplication.
Divide 86228364 by 2768 and check the answer.
Now to check the answer of the division: Dividend = Divisor × Quotient + Remainder, remainder<divisor 86228364 = 2768 × 31151 + 2396 86228364 = 86225968 + 2396 86228364 = 86228364
Terms of division Dividend: The number that is being divided. Divisor: The number that divides another number. Quotient:The answer of division. Remainder: The number left after division, it is always less than divisor.
Properties of division Division does not follow closure, commutative and associative properties. E.g. 68 and 5 are whole numbers but 68 ÷ 5 is not a whole number. E.g. 16 ÷ 4 ≠ 4 ÷ 16 E.g. consider (80 ÷ 10) ÷ 2 = 8 ÷ 2 = 4 80 ÷ (10 ÷2) = 80 ÷ 5 = 16 (80 ÷ 10) ÷ 2 ≠80 ÷ (10 ÷2)
Division by 1
For any whole number a, a ÷ 1 = a, E.g. 14 ÷ 1 = 14; 26 ÷ 1 = 26 Division by number itself
If we divide a number by itself (except zero), the quotient is 1. E.g: 276÷ 276=1 Division of 0 by any whole number
For any whole number, a ≠ 0, 0 ÷ a = 0, this shows zero divided by any whole number (other than zero) gives the quotient as zero. E.g. 0 ÷ 1 = 0;
0 ÷ 25 = 0; Division by 0
It is not possible to divide any number by 0. Therefore, division by 0 is not defined. Eg: 56÷ 0= not defined Division by 10,100,1000
When a number is divided by 10,100,1000 etc.., remainder digits will be equal to number of zeros. Ex- 67305÷ 10= Q=6730 , R =5 67305÷ 100=Q=673,R= 05 67305÷ 1000=Q=67,R=305

Ls-2 Amazing Animals (contd….)
Feeding habits –
Organs for breathing-
TYPES OF ANIMALS ON THE BASIS OF FEEDING HABITS
Herbivores
Animals that eat only
plants are called
herbivores .For
example- Cow, goat,
deer etc.
Carnivores
Animals that eat the
flesh of other animals
are called carnivores.
For example- lion,
tiger, wolf etc.
Omnivores
Animals that eat both
plants and animals are
called omnivores .For
example- human
beings, bear, crow etc.
Gills
e.g.fish, prawn ,
crab etc.
Spiracles
e.g.-insects like
grasshopper
Moist Skin
e.g.earthworm
ORGANS FOR BREATHING IN DIFFERENT ANIMALS
Lungs
e.g. mammals,
birds, reptiles
adult amphibians,
human beings etc.

Movement in animals –
Animals move from one place to another in search of food , shelter and to escape from
their enemies. Different animals have different types of adaptations for movement.
Dogs, cats , lion and human beings move with the help of their legs.
Snakes move on the ground with the help of their body muscles and ventral scales.
Fishes move with the help of their fins. While frogs use their back legs to hop and
their webbed feet to swim.
Birds can fly with the help of their wings. They also use their legs to move or hop.
Animals like penguins and seals swim with the help of their flippers.
Flippers for swimming Fins for swimming
Seal Penguin A fish
Migration- The periodic mass movement of birds and animals from one place to another
and back to their original homes is called migration.
The animals migrate from one place to another in search of food, to protect themselves
from harsh weather conditions and for better breeding grounds. Some examples are :-
1) The Siberian Crane nests near the north pole in summer and flies all the way to
India in autumn to escape harsh cold conditions.
2) Salmon fish migrate from saltwater to freshwater for reproduction.
3) Monarch butterflies, which are native of North America, migrate to southern parts
of California to spend the winter season.
4) Dragonflies migrate to southern part of Asia during winter seasons.
5) African elephants migrate in search of food during changes in resource availability.
