[quote=\"MummyJamie\"]Sally baked some cookies to sell. ¾ of them were chocolate cookies and the remaning were almond cookies. After she sold 210 chocolate cookies and 5/6 of the almond cookies, she had 1/5 of the cookies left. How many cookies did she sell?


That one was 960 right?

Most of us got that.

Yea, i hope so too
my daug didnt noe how 2 do the geometry qn...did u get 36 for the last qn? n 11:06am for the qn on spd??? >.< =.= thnx

Speed, yes, I got 11:06. For the last question, i got 68 T.T I think it's wrong.[/quote]Hi mummyjamie, answers are correct for both questions! Most people used ratios and cross multiplication/Sakamoto method to soolve the last question, I heard.

Hei, Pupils, For the Q with the Curry puffs, the correct ans is 71. You should have 17x4, which is 68, plus 3 more curry puffs, which is 71.


For the Q17 which is geometry Q, ans. is 150 degrees.

For the Q with the cookies, all of you have got correct - 960, but my daughter has got wrong for that Q.

If somebody remembers some more Q-s, please, I will be happy to know ;D :lol:

The Speed question (if my DD remembered correctly):


Mei and Lin take part in a cycling race.
Mei's speed is 20km/h. When Lin travelled half of the distance, Mei was 3.5km in front of her.
Mei reached finishing line at 10.45am.
What time did Lin reach the finishing line?

Similar feedback - paper was tough, finished all but not a lot of time left to check through. Anyway, its over now, just move on and focus on next few papers.

So take the total distance to be 2 units.
When Mei travels 1 unit + 3.5km, lim would have travelled 1 unit.
When Mei travels 2 units + 7km, lim would have travelled 2 units. (just finished the race).

So Mei needs to overshot by 7km.

Time = Distance/Speed = 7/20 hours = 7/20 x 60 = 21 minutes.

Lim needs to run 21 mins more.

10.45 + 16 mins = 11.06am

the paper is super easy and i finish everything in 1h 15 mins :lol:

I think 1h 15 min is too long. I knew of one who finished the paper in less than 45 min.

Omg! I can't believe I'm reading this...esp from a tutor.

Tutoring is a challenging job these days with PSLE Maths questions harder than O levels E Maths, and PSLE Science incorporating triple pure science concepts. May the best students be rewarded, whoever their unsung tutor hero (MS/AT/JA etc) is/was.

Hi small and Muffins


I bet many wouldn’t want to be in my position. I am just a victim of circumstances; my pockets are not deep enough to send my kid for enrichment courses. As you know, courses specialising in Maths Heuristics do not come cheap. So, I have no choice but to read up and struggle to keep in touch with the current trends in primary Maths.

Like many PSLE kids, I am eagerly waiting for the exams to be over.

how did your kid do for the PSLE Maths paper?

PS

By the way I am not a tutor :lol:

Hi James

I hear your roar of concern, but regret that I am unable to tell you more.

My boy looked worried and didn’t want to talk much about the paper and I don’t have the habit of probing for more. The ink on the answer sheets had dried up; and we will learn to accept the outcome, whatever it may be.

Moving forward, we will hold his hands if he stumbles and share his joy if he soars. As parents, we have to face the result, accept it and move on as he continues with his life journey. Like the famous saying in football, we may be a goal down, but the game is over only when we hear the final whistle.

It wouldn’t be polite if I don’t answer your query. But if you look at my previous posts in KSP, other than asking/answering questions, I don’t talk much about other happenings, and I hope you’ll refrain from asking me such questions in the future.

I value my privacy and I hope you’ll understand this.

Best wishes

I'm Jamie, child of my mum's account XD


PSLE Maths was tough for me. I was able to answer all the questions, though. For the angles/geometry one, most of my classmates got 120, 135 or 150. I used guess & check at first, but then used ratio and got 120. Anyone used ratio & got that too?

mine daughter also use ratio and get 120

OKAY, WILL SOMEONE PLEASE ENLIGHTEN ME ON WHAT THIS GEOMETRY DIAGRAM LOOKS LIKE? MY SON TRIED TO DRAW IT, BUT I SAW NO 60, 120 OR 150 DEGREE ANGLES ANYWHERE...
