Math: Angles Online Activity

Today, we started on a new topic: Angles.
We went to our NHSB Math Room to work on some online activities.
It was fun rotating virtual protractor, trying to measure angles of different sizes online.
We must remember to place the vertex of an angle in the middle of the protractor.
With one line of the angle along the base line of the protractor, start to measure from the zero mark.

Here is the website which we used in class:

Math Reasoning Blogging Activity

Dear boys and girls

This term we have started a new bi-weekly blogging activity during our Math lessons. Through blogging, we answer interesting Math questions whereby incorrect solutions to Math sums are given.

Individually or in pairs, all of you attempt to provide mathematical reasoning to highlight 'What's wrong" in the given solutions.

It was great fun during our 1st blogging experience. Do log in to the school's EDP portal to read your friends' comments and teacher's remarks.

We have done Blog (2) this week. For those of you who could not complete Blog (2) activity, you may continue it at home.

See you soon for Blog (3) !

Chinatown Learning Journey

Dear 4B boys and girls, are you looking forward to our 2nd learning journey to Chinatown next Monday? I'm sure it is going to be a fun day learning something new outside the classroom! Let's pray and hope for wonderful weather that day! (16 April)

We had a great learning journey to Chinatown on 19 April 2010.
Here are the pictures!


Thian Hock Keng Temple:

• Temple of Heavenly Happiness.
• Located on Telok Ayer Street.
• Singapore's olderst Hokkien temple.
• Amazingly, no nails were used in building it!

The eager-to-learn pupils were with a knowledgeable tour guide, who was relating the history of the temple to the pupils.








The Ann Siang Hill was where bullock carts were used to transport water supply in Chinatown.
"Bullock carts water" = 'Niu Che Shui" in Chinese.


Monuments of Samsui Women who wore red headgears and worked on construction sites in olden Singapore.





Pupils walking along the five-foot way (shophouses).

English Activities

In unit 5, we learnt about the 'Instruction' text type.
We conducted 2 hands-on activities which aim was to follow the given step-by-step instructions to set up 2 experiments!





I enjoyed the Crystal-Making activity!
Many of you told me that you love the Balloon-Rocket activity!
See! Following instructions can be great FUN too!
