Let’s talk about what division really is — ** it is repeated subtraction**; much the way multiplication is

Let’s say I have the basic problem 16 ÷ 4. I could start with 16 and then subtract 4, subtract another 4, another 4, and another 4 until I run out and reach zero. I would have to do this 4 times. If I had 16 cookies that I wanted to share equally among 4 friends, I could do the “one for you, one for you, one for you, and one for you” process and still end up with 4 cookies for each.

But what about 375 ÷ 50? If I don’t know how to divide by double digit numbers, the repeated subtraction process might actually be a good choice . . . at least showing some number sense to know that 375 divided by 50 means **“How many 50’s in 375?”** I know if I subtract 50 six times, I still have 75 left. I can subtract another 50 and I have 25 left over. So 375 ÷ 50 = 7 with a remainder of 25.

69 ÷ 3 | 60 + 9 | (60 ÷ 3) = 20
(9 ÷ 3) = 3 |
20 + 3 = 23 |

391 ÷ 3 | 390 + 1 | (390 ÷ 3) = 130
(1 ÷ 3) = cannot be divided |
130 with Remainder 1 |

Face value of a digit is the digit itself whereas Place value can be termed as the location of the digit in the numeral.

The value of a place in the place value chart is 10 times the value of the place just to its right.

A quick look at the grade 2 lesson on introduction to multiplication

Taming the tables – Tips to introduce multiplication

An even number ** x** an even number = an even number

An odd number **x** an even number = an even number

An odd number** x** an odd number = an odd number

Grade 3 Science(NSO) : Human body part 2

This system controls all our actions, sense of feelings and thinking is called Nervous system.The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring.

- It consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body
- Brain is the most vital organ of our body
- It sends and receives messages to and from all parts of the body through nerves
- Spinal chord is the bundle of nerves that runs up and down the center of the back; connects the brain to the nerves; carries signals between the brain and other parts of the body
- The
**brain**and**spinal cord**form the**control**center known as the**central nervous system**(CNS).

We have already covered Skeletal, immune, cardiovascular, muscular and integumentary system in part 1.

Grade 3 Science (NSO) : Human body part 1

It is responsible for the removal of interstitial fluid from tissues. It absorbs and transports fatty acids and fats as chyle from the digestive *system*. It transports white blood cells to and from the *lymph* nodes into the bones.

-picks up fluids leaked from the capillaries

-supports immune systems: houses white blood cells Continue reading
