PSLE FRP Math: Why cross multiply?

25 Jul


A subscriber of asked:

Hi! My daughter has been watching some of the FRP videos and the most recent 
one she is looking at is the P6 Set B Rev Up. 
She realised that "cross multiplication" occurred many times. 
She does not understand why she must cross multiply. 
Is that a special method? 
How does it work? I would be grateful if you could help us. 
Thank you very much! 
Warm regards Kelly :)

Our reply:

–This part of the working for our students will be the mechanical part of the working after the set up. A quick way to understand is: 1u + 10 / 5u – 30  = 1/3

So essentially you are cross multiplying the above.

–You could understand it through equality …meaning: 2/3 = 4/6, cross multiply you get 6X2 = 3X4 . So cross multiplication holds true.

If you are drawing bar models, you could explain it with parts and units. So 3 of (1u + 10) equals 1 of (5u – 30). You can draw the 1u as a rectangular block.

Thank you so much!! My daughter understands the bar model
She says she now knows how to use the cross multiplication method. 
Thank you and the teacher very much for helping her.

Warm regards & with gratitude
Kelly :)

We are happy to reply to our subscribers.

PSLE A* Achievers

This June, P6 pupils will work on mock papers that comprise of both short and long questions. This is a good time for all pupils to go through a comprehensive revision before the preliminary exams.

As usual, trainer’s explanation of difficult concepts in class is key to helping pupils clarify doubts and misconceptions so pupils are strongly encouraged to ask questions in class.

Practice is the other key ingredient for success in PSLE Math. Hence we are going to have an intensive program that has systematic coverage of PSLE math topics, emphasizes on higher order challenging problems and where pupils’ presentation of solutions will be fine-tuned.

Its almost the last stretch, boys and girls…..let’s stay focused and push on!


The Preliminary Round of the National Mathematical Olympiad of Singapore is on 1st July 2015, Wednesday. Top scorers will be invited to the Special Round on 28th July 2015, Tuesday.

We continue our intensive training to help P4 and P5 pupils in their preparation for the coming NMOS competition. Knowledge, understanding and skills will be built up through active teaching and learning in class.

Working on mock papers will also give pupils more exposure to the topics and questions most relevant to the competition.

P5 Problem Solving Heuristics

Primary 5 is a crucial period of learning for pupils as they head towards their PSLE next year. As essential skills are taught, pupils build up a stronger foundation and their ability and confidence soar.

We see this in pupils who started their P5 year with us, soaring ahead in their P6 year. We are happy for them, especially those who initially came in with low marks and lacked confidence.

As always, trainers will explain strategies in class but pupils’ attentiveness and diligence in practice is still key to their achievements. Time to work hard, boys and girls!
