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"
  • you may use your camera phone or your device's application such as PhotoBooth
3. In your Maths blog, in the same blog post:
  • Title of Post: Number Pattern Activity - Group 5 Question 4
  • Post a photograph of your suggested solution
  • Embed the video clip just below the photo
  • Include the name of all the members
On top of that, you've been invited to the G+ Event.

Number Pattern Challenge: 4, 5, 9, 18, 34

Number Patterns: Some interesting information

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

(from wikipedia

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:

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.

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).

Update: Those who responded to the Survey-Quiz

Here's an update, till 12 noon today.

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)

Enjoy your exploration with Donald Duck!

[Someone asked....] Solving Algebraic Word Problems

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.

  • Click at the slides to proceed.
  • The working in each slide addresses to a part of the problem (highlighted in red).

Little Red Riding Hood needs help!

Diagram constructed by Dominic

Where to meet

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

Resources for Level Test 2 Revision

Dear S1-02

Please note that the suggested solution for the various papers were already uploaded in your class GoogleSite: Refer to the "02 Revision" folder

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.

You must hand in these owed assignments by next Tuesday (12 August) by the last period; otherwise, you will have to stay back after school to complete and submit your work.

For those who failed to submit the assignments, you will stay back after school to complete & submit them (12 August; 2 pm to 3.30 pm @ Tutorial Room 1)

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
The answers for the above would be uploaded after the weekend.

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.
