* The answer to the Math problem below is in the comments section*This is the season again - right smack in the midst of intense revision and constant coaching for Big Bee's primary 2 final term exams. With no tuition or enrichment classes, I am her de facto creative writing mentor, English and Chinese tutor as well as Math teacher. Thank goodness my mum helps out with Chinese coaching sometimes!
Teaching and coaching is easy. Facing an occasionally irate child who is a perfectionist is a wee bit challenging. I believe in instilling discipline for children from a young age to be self-focused in their academic pursuits - which is not a relentless quest for perfection, but rather, ingraining a sense of responsibility and accountability. However, Big Bee carried this belief much further than I would like.
The evenings before her exams, she would get cold, sweaty palms and soles, although she still maintained a cheerful disposition. And she, very much like Hubby and me, prefers to work under stress and adrenaline, instead of dwelling in a complaisant environment with no pressure. As parents, we never ever gave her pressure to succeed and I tried not to talk about her exams as we revised her work, but she would give herself an invisible shroud of pressure.
Thankfully, we are now into her last paper tomorrow - Chinese. She slept easy tonight, ecstatic in the knowledge that she can celebrate and relax tomorrow afternoon. I had promised her that there would be no academic activities for a while, because I - like her - believe very much in the good old adage, "We work hard and play even harder".
Meanwhile, I am also looking forward to a breather from all these rigorous coaching, and to get back the momentum for more enjoyable homelearning activities with Little Bee, who had been feeling rather neglected this week.
To end off, here's a Math problem in her school workbook that was somewhat baffling for 8 year old kids, I thought. We managed to solve it for her (she was too mystified to solve it!), and I heard from Big Bee that no one in her class could solve it.
You have two empty pails. In one pail, you can put exactly 5 litres of water. In the other pail, you can put exactly 3 litres of water. You need exactly 4 litres of water. How would you measure exactly 4 litres of water using only the two pails?
On a lighter note, here's a composition from Big Bee that she wrote in May, which had gotten her 9/10 (4.5 marks each for language and content):
The Rescue
One windy afternoon, Danny decided to play with his new aeroplane that his father had bought for him for Christmas. Danny went to a park not far from his house. He went to a field near to a canal.
Suddenly, a strong gust of wind blew Danny's precious aeroplane into the canal! Danny did not want his precious aeroplane to be swept away in the flowing water, so he tried to reach for the aeroplane. As he was too near the edge of the canal, he fell into the flowing water in the canal!
He was afraid that he might be swept away with the flowing water so he shouted for help. Luckily, a young man who was coming back from work heard Danny's screams. He rushed to the canal as the screams were coming from there. The young man jumped into the canal and carried him out of the canal. He had rescued Danny!
Danny's parents were getting worried as Danny did not come home, so they decided to go to the park to look for him. Danny's mother was shocked to see so many people crowding around her son who was wet. The young man told Danny's mother what had happened. Danny's mother thanked him. She also gave him some money as a reward. That was Danny's most unforgettable day in his life.

hey Lin
that is for a 8 yo!?! I had to spend about 4-5 mins thinking about it before solving it too! oh gee!
jaime: Thanks for popping by! Yes, this is a terrible question for an 8 year old huh? Big Bee and all her classmates were baffled! Even Hubby and I were mystified for a little while. And there are many similar questions like this too...though by far, this looked to be the toughest. I dare not think of PSLE sums!! *faint*
I sure hope PSLE would not be that tough. Perhaps her school sets tougher questions? Jaime, at least you got it. I gave up after 3 minutes of thinking. Haha
Btw, Lin, can you kindly post the model answer for the question? There are supposed to be workings, aren't there?
Erm let me attempt my best answer ... And risk being laughed at... Take half of each pail ie the 5 litres and 3 litres - 2.5 + 1.5 = 4?
oh btw, nicole's composition is very impressive
ya i was coming back here to say what i forgot to mention yesterday that BIg Bee's composition is very impressive. I thought the bit about giving money to the rescuer is very interesting, especially after what we spoke about her after that burger date :)
K: This question was posed from their school workbook, which means their school curriculum textbook, assumably vetted by MOE and used by most primary schools! I guess they want to encourage creative problem-solving skills, but I thought it might discourage most kids at this age! Thanks for your compliments on Nicole's compo :)
Yellowgiraffe: Thanks for your encouragement on Nicole's essay. Yes! I also thought it was funny that she put in that sentence about rewarding with money, because, as we discussed, her language of love is never gifts...but maybe she assessed this situation of rescuing a stranger in a different light? And good try on the solution here! :)
All: Here's the "model" answer from the Math teacher. As this is not within the typical working of modelling, the answer is in logical word format:
1) Fill the 3-litre pail with water
2) Empty the water into the 5-litre pail
3) Then fill the 3-litre pail with water again
4) Empty it into the 5-litre pail until the 5-litre pail is full. This will leave 1 litre of water in the smaller pail.
5) Then empty the 5-litre pail
6) Pour the 1 litre of water from the smaller pail into the 5-litre pail
7) Fill the 3-litre pail again
8) Pour the water into the 5-litre pail and you will have 4 litres of water in the 5-litre pail
Now, which normal 8 year old will dream of this solution? Unless MOE's using this to look for those needles in the haystack - prodigies and Math geniuses! *faint*
Oh I forgot to post my own version of answer, which I thought is quite plausible too:
1) Fill the 5-litre pail with water.
2) Pour water from the 5-litre pail into the 3-litre pail. There is a remaining 2 litres of water in the 5-litre pail.
3) Empty the 3-litre pail.
4) Pour the remaining 2 litres from the 5-litre pail into the 3-litre pail. The 3-litre pail now has 2 litres of water.
5) Fill the 5-litre pail with water again.
6) Pour water from the 5-litre pail to fill the 3-litre pail. (We just need 1 litre from the 5-litre pail to fill the 3-litre pail now).
7) 5 litres - 1 litre = 4 litres. The remaining water in the 5-litre pail is 4 litres.
I had to demonstrate using real cups with actual water to Nicole before she could understand.
wow! Big Bee writes so well!!!
The question is not really difficult as long as they think "out of the box". There definitely be a few of this olympiad questions popping out during the exam. Its where they know who the really smart one are.
Charmaine's mummy: Thanks for your compliments on Nicole's writing - I am trying my best to teach her creative writing myself, without enrichment. I hope for the best! As for the Math, oh my, you mean there will be questions like these during exams *faint* I hope I wont see any of such questions soon!
u certainly did a very good job! Think she writes better than mine (who used to attend creative writing classes) :)
the olympiad qtn might not appear in P2 but schools are preparing the children to tackle such qtns in prep for upper Pri and PSLE.
