June 25 on Nasi Lemak

In Singapore and Malaysia, a common breakfast food is nasi lemak - rice cooked with coconut milk (not healthy at all) and served with simple condiments and curry (Malaysia) or chili paste aka sambal (Singapore).

Killiney has been in business since 1919 starting off as the ubiquitous kopi tiam.

The pack of nasi lemak i had with kopi o is 100% organic - not a single synthetic material is used. Banana leaf is used to pack the rice, giving it a nice aroma as well. Had I used my fingers to eat it as it is done traditionally, you can see how we used to be green without having to say we were green.

A 2 unit x 2.5 unit rectangular sheet of banana leaf folds into a rectangular pyramid with a 1 unit x .75 unit base and .75 unit height. The unit is the length of iPhone 6. 

How much rice is packed into this package?

May 30 on Big Numbers

Big numbers are not so common.

But in today's newspaper, I come across several. Parents can use the newspaper as a source of guiding their children in learning mathematics.

In 1974, anthropologists in Ethiopia found the astonishing fossilised remains of a human-like creature who last walked the planet some 3.2 million years ago. | Straits Times

The above can lead to an understanding of the magnitude of the million. The fact that this year is just 2015 years after the birth of Christ makes 3.2 million years ago seems like several lifetime (literally!!) away.

Did you know that Singapore does quite a bit of business in exporting ornamental fish?

Value of Ornamental Fish Exported

2008 USD69 million

2009 USD60 million

2012 USD62 million

2013 USD56 million

Parents can use this with upper primary children to calculate percentage change. Or learn the use of line graphs to make predictions.
