Question from Parik

29 Apr

Dear Parik,

here are the questions your mum emailed us,

1) There are 225 apples and 253 bananas in cartoon X. There are 260 apples and 212 bananas in cartoon Y. Christopher transferred some apples and bananas from cartoon Y to cartoon X. In the end, 40% of the fruits in cartoon X and 70% of the fruits in cartoon Y were apples. How many fruits did Christopher transfer from cartoon Y to cartoon X?

2) Jug X and Jug Y contain some water. If 46.5 ml of water is drained out from Jug X, the volume of water in Jug X will be 60% that of the water in Jug Y. If 35.2 ml of water is drained out from Jug Y, the volume of water in Jug Y will be 85% that of the water in Jug X. Find the total volume of water in Jug X and Y.

3)Winston had 80 more cards than Melvin but 50 more cards than Jason. Winston gave half of his cards to Melvin. Melvin then gave one-fifth of his cards to Jason. If Jason had 62 more stamps than Winston, how many cards did Melvin have in the end?

Highlights of June Holiday Programme 2012

25 Apr

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!

Science Programme at Math Arena

Once again, Science Hub will be conducting quality and interactive Science courses during the mid-year holiday at Tampines. Our focus is on lively hands-on approaches in helping pupils find out concepts in relevant topics through exploration. Pupils will carry out experiments to enhance their understanding and grasp concepts fully.

Pupils are always telling me that our Science trainer teaches clearly and is most patient with them. They also look forward to his fun quizzes.This helps them to learn and absorb well in a conducive environment. They now have greater confidence and improvement in their Science results.

Actually, I always feel like attending his class too because of the great laughter and energy that come from the Science classroom! Alas, I am usually in the next classroom with my P6!

P4 NMOS 1 & P5 NMOS 2

The Preliminary Round of the National Mathematical Olympiad of Singapore is on 27th June 2012, Wednesday. Top scorers will be invited to the Special Round on 14th July 2012, Saturday.

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 lack 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!

Dear Si Jie,

here are the questions your mum emailed us,

1) John uses 2 hoses to fill an empty inflatable pool with water. The first hose can fill up the pool in 3 hours. The second hose can fill up the pool in 2 hours. After an hour, a hole appeared at the bottom of the pool which could drain it in an hour. How long did it take to drain the pool completely?

2) A stream of water flows into John’s pond at a constant rate. John wanted to drain his pond so that he can remove the pebbles at the bottom of the pond. If he uses 3 pumps, he will need 3 hours to drain the pond. If he uses 2 pumps, he will need 6 hours to drain the pond. How many pumps would he need to drain the pond in 2 hours?
