🎉 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 Challenge 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 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)

Welcome — Committing to Learning, Growth and Purpose

Some words of wisdom shared in Mr Chan’s opening address closely align with our desired learning attitudes in the Mathematics classroom.

Below is advice from your seniors (2025 S1) as they reflect on their journey.

Always remember your basics first

Always think you don’t know anything so you have to go learn everything

Ask questions if you don't understand any concept or question

Ask questions if you're unsure (through email, WhatsApp, class chat, etc)

Ask your math teacher if you come across a math problem that you are unable to answer or if you do not understand a topic that well. They are kind and will not bite if you need help.

Do not stress too hard on mathematics, and always try to pay attention in class. If unsure, go ask your classmates and teacher for help.

Do your best

Don’t forget old subjects

Don't ignore certain certain assignments or ignore what is said in class

Don’t stress and pay attention

Focus in class

Honestly if you’re struggling with math, just take 5-15 min to do some math practice everyday or during weekends and it can help

I think you should not try to over complicate it, simply learn well and try not to be too stressed over work

Just do more revision

Just do well and do your homework (the side effects of not doing hw is deadly)

Just listen and everything will be easy

Just make time for studying and it will be very easy.

Just practice and revise math which is useful

Just practice questions especially those of topics that are confusing and do not hesitate to ask questions to clear up any confusion as soon as possible.

Listen for the last few subjects just trust me 🙏

Manage time

Pay attention to new sub-concepts. You may think Secondary one is just expansion on what you have learnt but the new logic you have to use will surprise you.

Practice Math. Do papers and questions.

Remember all algebraic concepts well and you don't need to memorise all the mensuration formulas as it will be given to you but it's still good to do so (so just pay attention during class)

Remember the formulas

Repeatedly do many questions to have the habit so doing questions in the exam will be fast and smooth

Revise on a notepad and take notes and revise them before exams

Start studying latest by March because the topics covered require a lot of memorising

Study a bit every day so it adds up

Study a lot more for algebra and do not hate maths.

Study consistently

Take a deep breath and don’t over think it

Take notes, focus and check work

They should listen attentively to classes and should always force themselves to try and understand everything the teacher is talking about, submit homework on time, read the study notes and do past year SST practice papers.

They should listen because as longa s you know what to do you will do ok

Try to read a little on new topics to get an idea of how it will be like and it helps to make the topic easier to understand

Try your best to keep up with the work and lessons

Understand first then memorise the topics

Keep these questions in mind when you watch the clip:

1. What I knew before watching the video.
2. What I learnt about the concept after watching the video.
3. What new terms (e.g. vocabulary) I learnt from the clip.
