Q&A - P1 Math

I thought the answer is 5 red balls too but one part of the question says \"6 balls from both boxes..\" so I got confused! Maybe there is a typo or just wring English.

This is from my P1 girl's practice worksheet.

Thanks for all the help. Maths sure is tough nowadays!

Yeah the question seems misleading! R u intend to clarify with the teacher & update us here

I mean like for parents, they should also learn maths with their children too!

[jeanieg]

Hi Jav think I will clarify with the teacher.


Yes, yomemai, I am also re-learning maths withmy girl. The problem is I have never liked maths so it’s a chore to relive my school years all over again!
Guess being parents in Spore, we dont hace a choice. Think am gonna look for a tutor for her as I just dont have the patience to coach.

Hi Michaelia0816, thank you for the reply…


Hi mrswongtuition, thank you for the reply and the suggestion on the use of different colour, that will really help the little one to visualise…

Just wondering, if the school did not teach, is it ok for the child to apply this concept when answering questions during homework time?

Alternatively you may use these interlocking cubes that are 1cm each to illustrate the problem as well.

It is also something hands on and similar to things that they come across and use in schools.

SINGAPORE:


Primary 1 Maths syllabus to be tweaked from next year


http://www.channelnewsasia.com/stories/singaporelocalnews/view/1200575/1/.html

Pupils entering primary school next year will be given more breathing room to grasp basic numeracy skills with the Ministry of Education (MOE) planning to drop part of the Primary 1 mathematics syllabus as part of its regular curriculum review.

A ministry spokesperson said that \"minor changes\" will kick in from next year's Primary 1 cohort.

For instance, Primary 1 students will no longer learn about measuring and comparing objects' physical mass through the use of non-standard units like paper clips and apples. They will also not be taught about 3D shapes.

They will instead learn about the orientation of objects such as whether they are facing left or right or pointing up or down.

\"These minor changes improve the sequence of the topics being taught without increase in content,\" added the spokesperson.

In tandem with these changes, the format of the Primary School Leaving Examination (PSLE) for mathematics will be adjusted for these students come 2018. No details on the format change are available yet, but the MOE said schools will be informed of the change two years in advance.

The syllabus adjustments come after the MOE's regular curriculum review - done every six years - and they are in line with the Primary Education Review and Implementation (PERI) initiated by the MOE to provide a more all-rounded primary school education.

Primary school teachers welcomed the latest move, saying it bridges current gaps in students' understanding and allows more time for students to grasp the remaining topics.

A teacher who has been teaching for seven years agreed that teaching children left and right orientation is useful because \"not all know their left from their right and this knowledge is needed when it comes to heuristics problems\".

Another primary school teacher with more than 30 years of experience said: \"The syllabus is already very tight for Primary 1 and doing away with some topics will allow for more breathing space.\"

Noting that not all students enter primary school with a good knowledge of numeracy, she felt lightening the syllabus load will give teachers more time to impart basic numeracy skills.

\"It is important to have a strong foundation so that it will be easier for them to understand more difficult concepts later on,\" she said.

Help needed.


Can anyone help to solve this P1 math test Question:

Bala has 6 white ping-pong balls.
He has to colour them yellow or blue.
There must be at least a yellow or a blue ball.
How many ways can he do it? (Hint:make a systematic list)

My answer is 7 ways. The school’s answer is 5 ways. Which is correct?

[phtthp]

thought only 5 ways, to add up to 6 :-


1\t5
2\t4
3\t3
4\t2
5\t1

you have 7 ways - is it because you’ve included these 2 below ?
0\t6
6\t0

but then test question state "There must be at least a yellow or blue ball", so need to exclude these 2. Hence, 5 ways only.

wah biang ! Now, P1 qn a bit "chim & tricky". They actually test whether children understand English what it mean by "at least a …" ie. "1 or more"

Thanks phtthp but I'm thinking: :oops:


0yellow 6blue – Don’t it meet the “at least a yellow or blue ball” – there is at least a blue ball right?

6yellow 0 blue - Don’t it meet the “at least a yellow or blue ball” – there is at least a yellow right since it say ‘OR’ instead of ‘AND’?

Please enlighten me. :?

May I also ask if the qtn read this way: There must be a yellow or blue ball. Is the answer be 5 ways too?

Hmm.. can we find out?
i think it's 7 too as it says 'or'.

i kaypoh .. posed your Test qn to Dr. Yeap Ban Har.

below is his reply:-

================================================

....this is based on Chapter Two - Number Bonds

0+6 and 6+0 are out -
because there must be at least a yellow or blue ball.

answer: -
Total 5 ways:-
1+5, 2+4, 3+3, 4+2, 5+1
