[Complete by 5 May] Challenge: Algebra: QUADRATIC EXPRESSIONS - Expansion/ Factorisation (BEGINNERS)

This quiz was posted in the ChatSpace on WED (29 April). 




Study Notes [Practice 15] p6 - Class Discussion

Hi Everybody

We did not get the time to discuss your worked solution during the lesson.  

Here's the feedback to your work & the suggested solution

(a) LINK to clip to explain


 

(b) LINK to clip to explain



(c) LINK to clip to explain



(d) There are 2 ways to factorise the expression
  • LINK - to factorise without removing the common factor first
  • LINK - to remove the common factor first



(e) There are several ways to approach this question.
Primarily... to extract the common factor across all terms first OR doing that as the last step (which is an often forgotten step). 

Included here are clips that demonstrates 2 ways to factorise by extracting the common factor first.
  • LINK - involving reorganising the terms
  • LINK - recognising "1" as a common factor for one of the pairs of the terms. [New!]







Group points: 
  • Black 1 point
  • Green 2 points
  • Orange 2 points
  • White 2 points
  • Yellow 2 points

🎉 It's PI π day!

Someone claims that by performing the operation (shown on the right) will result values that converge to π . Click HERE to watch the clip.



With our limited knowledge (as we have not learnt theorems, complex concepts, etc. yet), one way to check this out is using spreadsheet.

So far, we have learnt how to copy cells and insert formula into cells. 
Let's try to check the claim with the skills and knowledge we already know.
Make a copy of the GSheet and start trying to use the formula.

GRAPHING Challenging with GSheet

Rationale behind the Challenge

When we gather data through a GoogleForm, it generates various kinds of charts automatically. However, at times, it may not fulfill all the requirements (e.g. a title that is different from what we want, the axes are not completely drawn).

As such, we need to know how to use GSheet to plot our own charts - where we can customise to meet our needs.

The Task

Click HERE to access the spreadsheet where the table is already created.

  • (1) Make a copy of the spreadsheet and save it in your GoogleDrive.
  • (2) Create the charts (Bar graph, Pie chart).
  • (3) Post a screenshot of your chart under your group.

Each chart successfully created (and include the key features in the same) will be awarded 3 points 🎁

Study Notes (Task 2) Examining the charts more closely

Study Notes p6 & p7
We completed p6 during lesson.
- Complete the class work we did - Study Notes (p7) Complete (2C) PIE CHART & (2D) LINE GRAPH and post your work in the Padlet.



Study Notes (Task 1) Revisiting Pictogram, Bar Graph, Pie Chart & Line Graphs

[same post in Google Classroom, posted on 2 March 2026]

In primary school, we learnt what the different visual representations are and how to read them.
At secondary level, we are going into greater depth looking deeper into the characteristics of each visual representation, the advantages and disadvantages of each type, AND how to interpret the info to aid decision making.

In Task 1, we will recap our knowledge by going through 3 SLS lesson materials. 
Then we summarise them in a graphic using FREEFORM.

👉 The SLS lessons are already assigned in the SLS. Attempt them and draft the notes in your study notes (that will be given to you on in class)
👉 Submit an image of your summary (graphic from FreeForm) in the Padlet

Estimated duration: 50 minutes (over 1 week period)
Deadline: 9 March (MON), 0900 (before 1st lesson of the week)
