22 Jan (01): Prime Factorisation (continues...)

Textbook p9 #25:

The Prime factorisation of a number is 2^4 X 3^5 X 7^2 X 11.

Write down 3 factors of the number that are greater than 100.

(Hint: 16 X 11 = 176, which is a factor.)

2^4 X 3^5 X 7^2 X 11 = 2095632

The factors of 2095632 is 176,538 and 891

The Prime factorisation of two numbers are 2 X 3^2 X 7^3 X 13 and3 X 7^2 X 13^3 X 17 .

Write down 3 common factors of the numbers.

2 X 3^2 X 7^3 X 13 =80262

3 X 7^2 X 13^3 X 17 =5490303

The three common factors are 1,3,7

Textbook: Brainworks (p8) Q24(b) A mathematician proposed that "Every even number greater than 2 can be expressed as a sum of two prime numbers." Do y

I agree. Because...

4 = 2+2
6 = 3+3
8 = 3+5
10 = 5+5
12 = 5+7
14 = 7+7
16 = 3+13
18 = 5+13
20 = 7+13
22 = 5+17
24 = 7+17
26 = 7+19
28 = 5+23
30 = 7+23
32 = 3+29
34 = 17+17
36 = 31+5
38 = 31+7
40 = 37+3
42 = 37+5
44 = 41+3
46 = 41+5 since it still works until 46...

Communication

1 Why is communication important?

It is important because if we do not communicate we would be

very lonely and we would seemed like we do not know each

other.

2 What is/are your favourite form/s of communication? Why?

My favourite forms of communication is social networking sites,

the phone and the newspaper

3 How do you decide which form of communication to use in a

situation?

It depends whether it is a personal or non-personal message.

4 What difficulties do you face in communicating with others?

Some people don’t listen when you are trying to talk to them.

6 Jan: The Amazing Race - Debrief (II) Personal Reflection

Today's amazing race was very fun. I understand that the school value ''Expanding Our Learning Networks'' means that SST wants us to learn beyond our classrooms. The value is important because it is important for us to experience what we learn instead of just learning from textbooks.

5 Jan: Team Building Challenge - Debrief (II) Personal Reflection

I think that the school value forging excellence means that we should do the best in whatever we do. It does not only refer to our exams, it also refers to the projects and other activities. I think I am quite a hardworking boy so this maybe able to help me to achieve excellence. But one thing for sure no one is excellent. I think i should communicate more with my friends so I can excel in the things i do and help the class to succeed. :D

Bridge building activity-Self Reflection

I feel satisfied at the end of the day working as a group as my teammates were great and they came out of many different ideas.I think that although I had quite a number of interactions with the team I thought I could do better the next time. I learnt that I need to collaborate more with my teammates in future. At first i was a bit uncomfortable because i do not like to work with strangers but through the building bridges project I am now a bit more confident in working with strangers.
