Tutor MathsGuru: Ask me for your burning Maths questions!

Hi Chiefkiasu


I observe that mathsguru has been active in her responses to queries. Would it be possible to make her thread a sticky one or place her thread as one of subset of PSLE Maths? Otherwise it will be a waste if her thread disappears from the radar screen.

It will certainly benefit parents/students in the long run if she continues to be active in answering questions. Of course, this arrangement will only stay if she is active.

Best wishes

Thanks for MathGuru's commitment in Math solutions!

Perhaps it is good to indicate which level is the questions posted.
Or are these all PSLE P6 questions only? :thankyou:

You're right Tianzhu, Mathsguru's thread should be a sticky for more efficiency in going into her thread, to see the problems she has solved!

Mathsguru, you are a very commited kiasuparenter, and thank you for all the sums you have solved so far! :thankyou: :udawoman:

Ty Muffins, Tutormum and Mathsguru for ans! Now i understand how to do it.


Next ques: The sum of two numbers is 15 but the difference is 7. Find the bigger number.

It seems like I'm the only one who keep asking ques :lol: Paisey.
I know the ans is 11 but i duno hw to guide him thru explanation.

Hi Seekinghelp, the problem can be solved in two ways. Both, easy to understand and explain. I'll give both of them.

The first way
15 - 7 = 8
8/2 = 4
15 - 4 = 11

The second way is longer but easier to explain...
Bigger number + smaller number = 15
Bigger number - smaller number = 7

So, bigger number + smaller number + bigger number - smaller number = 15 + 7 = 22

Which is the same as bigger number + bigger number = 22

So 1 of the bigger numbers is 22/2 = 11

Hope I helped!

To get the bigger number (big unit), do addition instead of subtraction.

15 + 7 = 22
22/2 = 11

15 + 7 = 22
22/2 = 11[/quote]I like using model in my solution as I think it's easy to see and the children will have confidence in model drawing when they go to upper primary.

B No [ ] [ 7 ] } Total 15
S No [ ]

So 15 - 7 = 8
2 units = 8
1 unit = 4
so small no is 4 and big no is 4 + 7 = 11

Can we have some computer lessons on how to draw image and post? :please: DS3 has been calling me a computer idiot. :x

2 big units -> 15 + 7 = 22
1 big unit (bigger number) -> 22/2 = 11

If a recommendation comes from tianzhu, it must be good .

Thread sticky-ed.

Dear all,


:thankyou: so much for your support!! You guys really made my day...

From the bottom of my heart, I truly appreciate your kind words and encouragement alot...I will continue my best to provide detailed solutions for your Maths questions! :snuggles:

FYI, this is the 1st time I'm \"active\" in any forum and am flattered to have my thread made \"sticky\"!! Hehe...I always just look-see, look-see in many other forums. But, I guess over here, I'm overwhelmed and touched to see so many kind-hearted souls sharing Maths solutions with one another, and that made me wanna do the same too! So, let's keep this culture and spirit going yeah...?

However, hope to seek your understanding that as I'm also a full-time tutor, I may not be able to respond to your questions/posts very quickly. Nevertheless, you have my word that I will check the forum at least once a day and help out as soon as I can. *promise*

Have a great weekend ahead everyone~~

Sincerely Yours,
MathsGuru

Hi all.in.one,

Appreciate your comment!

If you're referring to the speed questions posted by Suiyuan, I would say they should be P6 level. The first 2 ratio problems can be P5 or P6.

The sausage, water and number questions are rather basic questions that are expected of Pri sch students and they should be ard P3/4 level.

Hope this answers your question.

As a suggestion, perhaps in future, let's provide the level of the questions when posting them...?

Regards,
MathsGuru

Hi Tutormum,

To be honest, it's not difficult to use the comp to draw nice diagrams...it's just time-consuming! I believe you can do it too! (That's why if you notice, I did the 1st 2 questions in this thread by hand and scan in my solutions)

For the above question, I posted my solution as a picture. Basically what I did is to draw the diagrams in MS Powerpoint. Then, I save the slide as a picture and post it here. It's more troublesome at first...but once you have a few solutions, they serve as templates and you can just cut and paste them for future solutions.
