### 27 August 2014 - Group Work: Number Pattern Tasks

Within your group, you are going to be re-organised into 2 "sub-groups":

Each sub-group will be given a problem to solve.

1. Take a photo of your suggested solution - make sure the image is clear & big enough.

2. Take a short video clip - no longer than 2 minutes, post it in Youtube - name it something similar to "S1-02-Group 5 Q4"

Mathematicians have found ways that enable us to determine numbers in sequences easily.

They derive formulas to suit certain types of number sequences.

To find the sum of numbers in a sequence 5, 7, 9, 11, 13, 15 …, we can use the following:

(from

On the other hand, if we have another number sequence, 1^2, 2^2, 3^3, .....

we can find the sum of the square numbers using the formula:

They derive formulas to suit certain types of number sequences.

**For example, the number sequence 5, 7, 9, 11, 13, 15 … is known as an arithmetic progression with common difference of 2.**To find the sum of numbers in a sequence 5, 7, 9, 11, 13, 15 …, we can use the following:

### Update: Here's what you say...

This is the consolidated response from 21 students in S1-02 (up to 25 Aug, 12 noon) (with 3 repeated entries), in response to the survey to find out if they know where to find the learning materials.

Q3 & Q4 required submission the specific URLs when looking for specific materials.

Below are the many possible different ways that you can ask questions (if unsure of your work).

Q3 & Q4 required submission the specific URLs when looking for specific materials.

**In addition, 85.7% are able to provide the URL of the YouTube channel where to could find the lesson video clips and, 85.7% are able to give the correct URL to find the flipped lesson for geometrical construction.**

Below are the many possible different ways that you can ask questions (if unsure of your work).

### Geometry with Donald!

The short clip beautifully connects various concepts that we've learnt and will be learning in the next couple of weeks.

Look out for the concepts that you are familiar with (e.g. Golden Ratio)

Sometime ago, someone (from another class) asked how to solve the following word problem (from the Textbook).

Here's the step-to-step explanation on how to tackle this question.

### Where to meet

The location of the houses of three friends, Antonio, Benedict and Celine happened to form an

Diagram constructed by Gijoo

**equilateral triangle**. They meet quite often to catch up with each other; however, none of them want to invite their friends home. To be fair, they decided to meet at a place that is most 'central' to all.- What would you suggest?
- How would you do it if you have their houses marked on a map already?

*Note: There is a typo-error in the above diagram, it should be "Benedict"*

### Submission of Assignments

Many of you have not submitted the following assignments (in the last 2 weeks).

While these topics would be tested by Thursday (Level Test), you still have to hand it as you would need to demonstrate your understanding and mastery at the end-of-year exam; and you need to know them well when you move on to other levels.

### Maths Consultation (T3W6, in place of Support Programme)

Term 3 Week 6 is the level test week.

This week, the remedial programme would take the form of Consultation Period.

I would be available from 2 pm to 4 pm at the InfoHub (Level 4).

You can come to see me to clarify your doubts if necessary.

Bring along any handouts or questions that you have so that I could narrow down to explain what's needed.

With regards

Ms Loh

### Australian Mathematics Competltion

Please be reminded that the competition will take place on

You are required to report to the above venue at 1.40 pm sharp.

7 August 2014 (Thursday)

2 pm – 3.15 pm

Auditorium

Click HERE for more read the detailed instructions (e..g scoring system, what's allowed to be used for the paper).

### Revision for Level Test 2

The following papers were given to all in the past 2 lessons, in preparation of the revision.

- S1 Maths Revision for Level Test 2 (Questions by Mr Desmond Peh).pdf
- S1 Maths Revision for Level Test 2 (Questions by Ms Janet Tan).pdf
- S1 Maths Revision for Level Test 2 (SST 2013 Maths Level Test 2).pdf

**How would the revision look like next week?**- As mentioned in class, we'll go through
- selected questions of the following papers during class time:
- S1 Maths Revision for Level Test 2 (Questions by Mr Desmond Peh).pdf
- S1 Maths Revision for Level Test 2 (Questions by Ms Janet Tan).pdf
- S1 Maths Revision for Level Test 2 (SST 2013 Maths Level Test 2).pdf

- selected questions from the homework (questions that some of you encountered)

- mock test question paper

- Note that we will not go through the MGS paper ((Optional) 2014 MGS Common Test Sec 2 Maths (Algebra)) which has the solution uploaded last weekend.

- You need
__not__hand in the papers for marking. They are meant for class discussion. - You should, however, make an attempt to think through (the steps) how you would answer the question because you may not have enough time to complete all the papers.

Remember to bring the papers with you for the lesson discussions next week.

*Note that the revision papers would also serve as useful resources for your end-of-year exam preparation, too.*
