Course Description


This course is targeted at Singapore primary school level 6, but is also suitable for primary school level 5 students.

Based on feedback, many parents have used the videos to learn the methods to help their children to learn faster.

Math Arena students gain an edge using techniques that we teach here in our videos, these methods provide accuracy and speed. We believe it also provides better understanding of their solution to the question that they are solving.

It can also be used as independent learning or for revision.

There are a total of 5 PDF sets for this series. They are arranged by similarity for easy question pattern recognition.

The Number of stars indicates level of difficulty. One star is fundamental, 2 stars are moderate. 3 and 4 stars are difficult and challenging. Note due to the student’s ability he may experience difficult questions as easy and easy questions as difficult. So do not be over anxious, if an “easy question” stumped you, just keep practicing.
