Please share TIA 🤗 !

I wish to boost my kid's problem solving ability and confidence for those 4-mark and 5-mark type of difficult PSLE maths questions.

I have already bought the https://www.ammielwan.com.sg/publications-1 from Ammiel wan math academy. The solutions are clear and give step by step instructions. My kid enjoys the challenge and requested for more similar practice.

I am also trying to buy the http://www.nicklebeetutors.com/p/math-resources.html p5 & p6 notes. The picture is from @mummyof3angels who has already sold her copy. Can't find on Carousell too. I called Nicklebee tutors but they don't sell to non-students. If anyone has a copy for sale please let me know.

I do not know. It’s probably too “simple” for PSLE.

I could solve it in few minutes without prior exposure. DH could not. DS could not either. But now they both know how. DS could eventually understand the Hexagon but not skii’s “intersecting” theorem.

Exposure is fine but there is no end to it if u want to keep chasing such qns, which may not come out in the end.[/quote]

That's what I told my little Clumsy one to do.

Sometimes it's so frustrating! He can get the workings correct and that make a blunder on the last line which gives him the wrong answer. But, the workings should help.

Will PSLE come out this type of questions? Under exam conditions, I probably can’t solve within 5 mins.

After I read the posted solutions, I now know the trick to solve such questions. Thus, I can understand why some parents choose to send kids to MO/Heuristic classes.

Discuss for fun:
- how many parents can solve this?
- how many of your P6s kids can solve this?
- how many of your kids could have solved this in P3 (ie. when the official textbook teaches the 5 times table & 6 times table)?

Qn: There are 24 boys in a class. The boys are sitting in 6 rows of 5. How is it possible? Draw a diagram.[/quote]

It is a general English word used by parents to mean the questions which sieve out the AL1 students from the rest.

Also used by educators, eg. quoted in this article https://www.todayonline.com/singapore/moe-caps-challenging-questions-psle-15-keep-difficulty-level-consistent-some-parents-call-lower-cap-1945681

“Dr Jason Tan, an associate professor in policy, curriculum and leadership at the National Institute of Education, said that the Singapore Examination Assessment Board applies rigorous processes when designing exams. This is done not through the questions themselves, but also in mixing the difficulty levels of these questions.

\"This is because a key function of exams such as the PSLE is to differentiate among various candidates. You need to have a combination of exam questions of varying difficulty that enable the examiners to make this sort of differentiation among candidates,\" he explained.

What is \"differentiator\" question ?

Under which ( P5 or P6 )
Maths MOE syllabus topic,
does it fall under ?

So now that the kids are home from school…ask your kids to solve. At P3, I doubt many will know how to solve it themselves without prior exposure.

It was an illustration of a differentiator type of qn that could come out at P3 (the parent who posted this in the FB help group clarified that it was from a non-GEP but SAP school).

For PSLE, some years there may be differentiator qns that kids with prior exposure would immediately know how to solve. Like my example — once youve seen it, u will know how to do similar qns. But in other years, SEAB will think of other types that need even more advanced logical problem-solving skills.[/quote]

just an example: (I hope it is easy to visualize, since i don't know how to insert a picture here)

say this # sign.
add two lines below, touching the vertical line at the bottom, one line extending to the left, one line extending to the right
to look like this _#_
(the two lines need to connect to the bottom of the hash sign)

this will satisfy the conditions of:
6 points of intersection
6 lines
5 pax on each line
24 kids


(I think la.... not a maths teacher. someone confirm?)

Interesting! My first thought was the hexagon because the “missing” 6 need to be “shared” or used twice at both ends of the row of 5. Hence the need for the closed loop.

Mind drawing out your suggested alternative?[/quote]

skii\" post_id=\"2075513\" time=\"1658378817\" user_id=\"82603:

6x5 =30 points required
since there are only 24 kids, there will be 6 kids (from their single point) but having contribution to two rows.


once we know that, just arrange the 5 straight lines with 6 points of intersection

(can be any shape, don't even need to be hexagon or etc... in fact, the lines don't even need to close off to form a particular shape)

My guess, it is a hexagon shape. 6 students shared at the 6 points. Then each row 3 pax?
