Number Pattern Question 2 (Kimberly, Lynette & Sabrina)

Kimberly, Lynette and Sabrina from S1-04

(Task) Number Pattern - Explanation of Solution

Objective of Task:
To explain how to solve a 'number pattern' problem by clearing articulating how to draw out patterns (from observation) to come up with a generalised form.

---

(A) Group Formation:

Each group (of 3-4) is assigned to answer a question in the exercise.
Each group is given an A4 sheet of paper where you would document your working.

[Leaders of each group]

• Q2: Sabrina
• Q3: Chester
• Q4: Nehal
• Q5: Kenric
• Q6: Timothy
• Q7: Luke

(B) What you need to do:

1. Spend 2 minutes on your own to look through the question and think how you would solve the problem.
2. Discuss as a group on how to present the solution.
• You have to think through, how you would explain your thought process so that your train of thoughts is clear to the audience.
3. Record the explanation (you may 'break' the explanation into several parts).
4. Take a picture of your solution.

(C) Posting your worked solution
In your post, include the following

• The video clip(s) - place them in order, and provide a short heading (when appropriate)
• An image of your worked solution (the question should be included)
• Include the names of all members in the group
• Use the subject heading: Number Pattern Question.....
• Add the label: number pattern
• Remember to include the names of the members and class at the end of the post
• e.g. Alabama, Bologna and Colin from S1-04

Number Patterns Question 1

(A) Generalising...


(B) Finding the 10th line...


(C) Finding the value of n...


(D) Calculating square of 199 using the pattern...

Scenario 1, Direct and Inverse Proportions.

Scenario 1

It is the December holidays and you have decided to apply for part-time work at the fast food outlet, MacDonalds. The pay is $4 per hour.

Think
1.What is the relationship between the number of hours worked and the amount earned ?
I earn $4 after working for 1 hour.

Pair
3. Graph of the line

The equation of the line : y=4x

4.Work out the last row of the table. The first one is given to you :
y/x: 4/1=4  :  8/2=4  : 12/3=4 : 4/16 =4  :  20/5=4

(i) Write down what y/x represents in your own words.
y/x represents the total amount of money earned divided by the total number of hours that I work for.

(ii) What do you notice about the numerical value of y/x? Draw Conclusions from (3) and (4i).
y/x always equal to $4.

Putting it all together.
This is a direct proportion, as when y increases, x increases. As X and Y are in a constant ratio.
