    Difficult PSLE 2019 Math Question!

    My gal is taking her O Levels this year. I see her Anderson Sec A Maths Exam questions...…..faint faint faint...….no way I can learn this again. Even my wife in the Science field says...…..why set the Chem questions so difficult!!! Siao!!!!!!!

    Difficult PSLE 2019 Math Question!

    The 1 x 1, 2 x 2 , 3 x 3 is pretty standard stuff. The rest is all about patterns and difference. Odd & Even is considered pattern...…….so its within the PSLE realm. Not a difficult question. Manageable with a clear mind. The problem is....setting it at the very last question, most pupils' brain already in moderate to high Haze levels liao……….lol I guess the Maths T-score will be push up 5 points at least ???

    Difficult PSLE 2019 Math Question!

    100% = 61.20. Not 70.38 Hence 9.18/61.20 x 100 = 15%......no ? Confuse Confuse Confuse...……...lolllllll

    Difficult PSLE 2019 Math Question!

    Can I ask the maths expert here on the egg tart question. My son got the answers as 46 tarts and $1.53, same as me...…….but the outside world says the answer is 40 tarts and $1.80. 😒 I cannot let go of this...……..cant eat cant sleep......but my son already lost in the Plug-G world liao...........lol.

    Difficult PSLE 2019 Math Question!

    Paper 2 long questions is always the killer...…….if you can get your kid to overcome this hurdle, the rest will be smooth sailing. What I taught my son to effectively tackle 4 & 5 marks questions within a standard 5 min time frame is to ALWAYS consider Model first. Bocs its usually the easiest and quickest way to tackle the question. (but not always) If cant do it, then clean off the model and try solving using Ratio. Lastly if all else fail, then use the long-winded algebra method ( we nickname this "equation method" bcos we are trying to form 2 equations from the question). Actually my son find "equation" model easier to do.....lollllllll. Hence u and see his algebra method attempt on question 16...…...lol The other main killers include the so call pattern/figure question (question 17 this year), "water tap questions", Dist/Sp/Time" questions. The rest I isolate them into "Miscs". And there is also the time management factor and recheck process. Paper 2 question 1 to 17 DIE-DIE must be attempted within 45 mins. Any question that needs more than 1 min of reading to understand and lift the pen...must SKIP IMMEDIATELY without delay. Any question exceeding the 1 mark 1 min rule...SKIP!!! We nickname these BLANK!! Usually he will have 2-4 of them at the end of Q17. At the end of Q17, go back to Q1 and recheck. DO NOT ATTEMPT THE BLANK QUESTION. Recheck is not just eye power only. Recheck workings first then the calculations. He is trained to read the question and point at his workings. Every information in the question MUST be stated in his workings. Then the calculator will conclude the checking and move on to next Q. Once rechecking is completed, he usually have between 20 mins to 40 mins left to tackle the BLANK questions...…….depending on the difficulty of the maths paper. It varies. Now Total focus on the BLANK Questions only. And more often than not, he could solve most of the blank questions. He can tell me which of his answers is 100% correct, which is only 50/50, he even got 70/30 and 30/70 opinions….and of course.....0% sure die...........lol My self-invent teaching method may not be perfect but its my best attempt to help my son tackle maths exams effectively and as less stressful as possible...……. Looking back, there was lots of ups and downs, frustrations, and sweat, sometimes even thots of giving up. Whatever the outcome is...…...we have done our best. I am glad that I went through this journey with my son. Today is the last PSLE paper, and he can finally resume his childhood activities. He earned it.

    Difficult PSLE 2019 Math Question!

    I would say Maths now compare to our days is totally different. Now there is a lot of English involve in the question. If you cannot digest the english, you cannot even lift the pen to write. ( not the DEAD-BRAIN kind of questions during our time) And Schools nowadays expect kids to have a lot of background on the subjects (presumably at home). The school just supplement it. (our days is the other way round) So I jump in the wagon and learn on my own. I actually learn a lot from Bro Ender. Replying this thread now (4am). It was like a norm for me to wake up this time(for countless nites) to self-teach maths or to think of a more efficient way to answer Science section B structured questions...…….its really really hard. I really pity my son. (that's also why ive been inactive from MCF for a long long time) The journey was very tough. My son was still getting Maths sub 50s for the whole P5 duration, even after guiding him for 1 full year. Fortunately P6 he manage to grasp it. P6 CA1 : 53%. SA1: 63%. SA2: suddenly he kai qiao and got 92.5 %(Pei Chun). That period between school SA2 exam and the PSLE exam, he did 10 x 2018 SA2 paper. The usual Rosyth, Henry, Cat high..... Scores range from 77% to 94%. Days before D-Day, we tone down a lot and he only did 3 more maths papers...... 2019 SA2 paper for Nanyang, RGS, Nan Hua(in my opinion the toughest). He got sub 80s. Not RI standard, but he has come a long long way.

    Difficult PSLE 2019 Math Question!

    Just download the CA1, SA1, SA2 papers from the internet. Search and you will find it. And throw in tons of time and effort into writing the worked solutions properly and systematically. (you need lots of patience and perseverance for this) Don't just see their suggested worked solutions....its crap!!! DIY via assessment books and YOUTUBE videos and make it as simplified as possible. Easy to understand Then pass on the skill to your kid. I did it from ground zero when my boy was P4...……….U can do it too!!!!

    Difficult PSLE 2019 Math Question!

    my son got 17a & B correct but left 17c blank.....Hiaz (he told me the whole PSLE exam P1 & P2, this is the only question he don't know...…..im like SURE BOR!!!!) LOL!!! My simplified version for 17c W (diff) G Total F1 1 1 0 1 (1x1) F2 1 2 3 4 (2x2) F3 6 3 3 9 (3x3) F4 6 4 10 16 (4x4) Since its a repeat pattern.....1 & 1 , overlapping 3 & 3. Grey F5 must be a overlapping 10 & 10 Since F5 total is a 5x5 = 25. Using basic model, F5 white must be 25-10 = 15 Now for F250...…….. Basically you have to test whatever self-invent formula on F3 & F4....if it works then proceed to find F250. Something like from Total how to get white, or from grey how to get total...….along this line (that's what I taught my son) Just test on F3 & F4...don't test on F2 cos its not accurate. Now using simple model to test on F3 & F4 & F5 U can see F3 is actually total 3x3 with diff 3. hence F250 will be 250x250 = 62500 with diff 250. using model, you will get 31125 & 31375 (grey / white, or white / grey) Which is which ????? Go back to F3, F4, F5.....see it like a model F3 White - Big, Grey - Small F4 White - Small, Grey- Big F5 White - Big, Grey - Small Its actually a sequence !!!!!!! Odd number - Grey is ALWAYS small Even number - Grey is ALWAYS big Hence for F250, Grey is 31375. White is 31125 % of Grey = 50.2 percent.

    Difficult PSLE 2019 Math Question!

    My son's exact working in PSLE (im very very surprise he could do this!!!!!!) let the unknown distance be X and Y 2X + 16 = X + 12 + Y 2X + 4 = X + Y X + 4 = Y 2X + 16 = X + 4 + 22 X = 10 Diameter = 10 + 16 + 10 = 36 cm

    PSLE Maths question. How to solve?

    If u have problems with P6 Maths Q, just drop a message. I should be able to help out a bit. (should only....haha) So far I have prepared worked solutions for 20 SA2 schools for 2018/2017. Plus complete 2016 to 2018 PSLE Q as well. Gone to hell and back to do this !!!! By far, the most lengthy and difficult to absorb Q is listed below....took quite a while for my P6 son to absorb it. Nanyang / 2017 / Q17 At first, Box M had 18 pears and 42 lemons while Box N had 36 pears and 50 lemons. Then, some lemons were moved from Box M to Box N and some pears were moved from Box N to Box M. In the end, Box M contained pears and lemons in the ratio 3 : 4 while Box N contained pears and lemons in the ratio 1 : 2. a) In the end, how many lemons were there in Box M ? ( 4 marks) b) In the end, how many more pears did Box N contain than Box M ? (1 mark)

    PSLE Maths question. How to solve?

    hmmm...make sense. 2U : 1U --> 4x4x4 : 2x2x2 = 64 : 8 ( 8 times bigger) hence 348/8 = 48. U are really good in P6 Maths. Thanks.

    PSLE Maths question. How to solve?

    PSLE Maths 2018 Q 28 (2 marks) - actual question Can somebody help me to answer this question...….in as simpler form as possible suitable for a 12 year old kid to absorb. Thank you. Jasmin formed two cuboids with unit cubes. The length, breadth and height of the bigger cuboid are 2 times those of the smaller cuboid. She used 384 unit cubes to form the bigger cuboid. How many unit cubes did she use to form the smaller cuboid? I got the answer by trial & error via the factors of 384. Wonder if there is a simpler answer. PS....I personally feel that the actual PSLE Maths Exam is a lot easier than the SA2 paper of some schools....(namely Nan Hua, Rosyth, Raffles....they set unbelievable difficult questions!! Put unnecessary stress on students.)
