Sports Day 2016!

A memorable day filled with fun and laughter. :)

Three cheers for coming in third in the level, 6D! Hip, hip, hurray! :)

Maths Brain Workout

Dear Maths professors,

Let's do some brain workout! Stay cool! :)

Q1) Note: Ignore the pencil markings on the diagram. 

Q2) 

Speed

6D professors experiencing how long it takes for one minute to pass... It's great to hear them share their strategies on how they estimated the duration of one minute. :)

Learning the concept of speed via mini competitions... :)

Character Values Awardees :)

Well done, children! :)

Speed

Hola, Maths professors!

Let's learn more about speed.

Speed is a special kind of rate. When an object is moving, the speed of the object is the rate of distance covered per unit time.

• Speed limits on Singapore roads



 



In a nutshell, speed is the distance travelled per unit time. 

Do remember the following three formulas well.

Note that the units used in D, S & T must correspond to one another.
 



 

Here's a video to help you remember how to get the formulas...

 

 

Oh yes! Just a question.

There are many different types of units that can be used for speed e.g. m/s, km/h, m/min, cm/s

How do we know when which units are more appropriate?
 

 

 

 

And now, it's time to learn about the amazing wonders of Mother Nature! :)

 

The speeds indicated in the video above is the average speed. This is because the speed throughout a journey may not be constant all the time.



Average speed = total distance covered ÷ total time taken

The average speed is not the sum of two speeds divided by two.

 

Our Task

1) Time your journey home from the same starting point in our school.

2) Record the time taken (duration).

3) Find the distance travelled using Google map.

4) Calculate the average speed of your journey.

5) Repeat steps 1 & 4 the next morning while you are on your way to school.
 

Have fun & we look forward to hear you share about your experiences! :) 



 

 



Sir Cumference, Perimeter & Area

Dear children,

Here's an interesting story on Sir Cumference, his wife, Lady Dia Meter and his son, Radius.
Hope you will enjoy it. :)

 

 

 

Circles

 

Circumference of a circle --> C =  πD  (Sir Cumference = Pirate  in Disguise)

 

Pirate = "π-rate"

 



   

 



 

 



Area of a circle =  π x r x r (Pirate in Rock & Roll)

 

 

 

 

 

Internal Transfer Lesson

Maths professors using interlocking cubes to learn about internal transfer...

The new difference always differs from the difference at first by twice the amount transferred...

Model Drawing: Fraction of a Remainder

Hola, Maths professors!

Here's a video to help you revise fraction of a remainder questions.

Remember to draw a diagram when the question is on fraction of a remainder.

Model Drawing: Internal transfer

Dear children,

We've learnt that in internal transfer, the new difference either increases or decreases from the difference at 1st by 2 times of the amount transferred.

Let us look at how the models for internal transfer are drawn when larger numbers are involved.

Notice how the 2 times of the amount transferred is represented.

 

 

Here's a more challenging question for you.

 

Set Grouping PSLE Revision Question

Dear children,

Here's the revision question as promised. Please jot it down in your Maths Journal if you didn't manage to finish copying the question stem in class today.
