Most schools I know are either finishing their exam by the next two days, or either finished dy. Except for Assunta, which will only have their paper AFTER holiday. O_O (Means three weeks from now). So most likely we cannot accommodate with them lo.
So next week me and Kok Kin agree to go into Chapter 7. Form 4: Probability I and Form 5: Probability II. Probability, say easy, not easy. Say hard, not hard.
Cause this topic right, they only need to know
1. sample space (possible outcomes), and
2. probability (possible outcome for an event = sample space with given condition).
But problem is, the questions can vary A LOT. Similar questions may have different ways of doing it.
Example:
A bag containing cards with number 1 to 5. Ali has randomly picked a card, and then he places the card back into the bag, and pick again.
a) List all the possible outcomes.
b) Find the probability that both cards picked are odd numbers.
A bag containing cards with number 1 to 5. Ali has randomly picked two cards.
a) List all the possible outcomes.
b) Find the probability that both cards picked are odd numbers.
Students usually dunno how and use what way to solve. Cause the question macam the same. So we need to teach them how to identify types of questions. I am still finding out how many possible types of questions are there, most likely by tonight I will post again. So try check ba.
But now the problem is, what do we teach and how to teach next week, and during the 2 weeks holiday??? Be informed that during the two weeks holiday, all teaching is activity based, so have to prepare game. -_______- So I plan to stick with probability until end of holiday. I plan like,
week 1 (next week)
F4: do introduction,
F5: revision for form4 + identify form4 question type
week 2 (starting of holiday)
F4 identify types of questions with games.
F5: teach their topic with games
week 3 (2nd week of holiday)
F4: I dunno yet. xD
F5: Identify Form5 questions + Form4 questions with games.
So Form 4, next week
1. introduction to possible outcome and sample space
Eg:
Toss a coin, list possible outcome. {H, T}
Toss two coins, list possible outcome. {(H,H), (H,T), (T,H), (T,T)}
2. What is event (A given condition to find possible outcomes)
Eg:
Toss a dice, list all the possible outcomes if the side facing up is an even number
{2, 4, 6} out of {1, 2, 3, 4, 5, 6}
So event = Subset of Sample Space (start crapping a bit about sets and pura-pura do revision for set a bit)
3. How to find probability (Introduce symbol P(A), where A is the event), and how to use probability to find expected number of times an event occur.
Eg:
Out of 10 girls, 2 are fat. If I have 360 girls, how many are fat?
Find probability = 2/10
Number of times event occur
= P(A) x 360
4. Give exercise.
Give different types of questions one, so they will like, "why everytime oso need to use different style to solve one". (But Form4 one quite shallow la, not as hard like the example of pick two cards above one) Then we say, next week, we will tell you how many types of questions that will come out. And next week is game based, so you want to master how to solve, then come. And this topic is important, cause' if you dunno this topic, Form 5 we got probability 2, then ur basic not good, Form5 very cham. Something like that la. xD
Here need to remind them to write full statement in Paper 2. Like how many are fat right, they have to write "Expected number of fat girls = P(A) x 360" like that.
That is for Form 4 la. Basically that covers the whole chapter.
Form5:
1. Revision for Form 4. (Do exactly what you will do for Form 4 class, except that you make it shorter)
2. Introduce the types of questions and let them do the same type for a few times, then proceed to next type until they recognize the way to solve.
That will eat up all the time for Form5. So for types of questions, please check blog again tonight! Thanks.
PS: This post macam sangat leceh leh. haha
noobiak signing off. xP
