For March holiday program, it will be preparatory work for the NMOS competition.

In June holiday program, the content structure is entirely mock paper training.

The purpose of our lessons is to build a firm foundation for students.

The tougher mock paper questions are actually not “difficult” as they are simpler concepts coming together.  Students who find themselves unable to cope with tougher questions actually still have issues at their foundation. Once the foundations are strong, questions they used to find “challenging” are no longer an obstacle to them 🙂

Learning Fraction, Ratios, Percentages Fundamentals 2

3 Feb


We continue our discussion on learning fraction, ratios and percentages by studying the question below;

This is a P6 SA2 question. It is relatively simple. How would you solve it?

Nellie plans to make 340 bands to sell at a bazaar. Each day, she will make 4 more bands than the previous day. She plans to complete the bands in 5 days. How many bands does Nellie plan to make on the first day?

Using algebraic notation would be a neat way to present it. However for primary school students, we could also use a unit to communicate the same idea.

Check out the video solution here

Part 1 is here.
