[poppy15]

ksi:

Aiyo poppy, don't make me blush.. :oops: :oops: :oops: , there are many experts here. I am just a mummy trying to help my baby. If your child has a problem in Math, just post, I will help to solve. After looking at a few solutions, you can master it too.

kekekekek... u will see me more often here (actually i hope not) in this thread next yr once my DS enters P1 & :imdrowning:

then i will keep pressing :?: :?: :?:

teacher in his K2 class js feedback to me he gets confused between more than & less than... aiyoooooooo :faint:

Hi poppy15
This is common among K2/P1 kids. I faced the same problem with my P1 girl also and started a thread asking parents here for advise.

:thankyou: Yong HL

after looking thru that thread, its still doesnt reveal the answer :oops:

a) 2 is ___ less than 10
b) 3 is 4 less than ____

so i read over & over again (read: slow digestion) & after cracking my brains, can i finally say the answer is as follows:

a) 8
b) 7

(a) we use subtraction & (b) we use addition but how can we teach the kids using K2/P1's language

looks like i got to prepare a list of sums & get DS to do it, then slowly try & explain to him...

Solving questions on 'more than' and 'less than' sums


Type 1
_______ is 5 less than 12.
Cover up 5. The question will then be read as ______ is less than 12. Therefore _____is the smaller number. To find the smaller number, we always need to subtract. The answer is then 12 - 5 = 7.

Similarly
_______ is 2 more than 12
Cover up 2 again. The question will then be read as ______ is more than 12. Therefore ____ is the bigger number. To find the bigger number, we always need to add. The answer is then 12 + 2 = 14.

Type 2
3 is 4 less than ____
Cover up 4. The question will then be read as 3 is less than ______. Therefore 3 is the smaller number and ______ is the bigger number. To find the bigger number, we always need to add. Therefore the answer is 3+ 4 = 7

10 is 6 more than _____
Similarly cover up 6. The question will then be read as 10 is more than ______. Therefore 10 is the bigger number and ______ is the smaller number. To find the smaller number, we always need to subtract. Therefore the answer is 10 -6 = 4

Type C
2 is ___ less than 10.
In this question, we are comparing the 2 numbers, 2 and 10. 2 is less than 10 but by how much? To find the answer, we use the bigger number minus the smaller number, that is, 10 - 2 = 8.

10 is ______ more than 4.
In this question, we are comparing the 2 numbers, 10 and 4.
10 is more than 4 but by how much? To find the answer, we again use the bigger number minus the smaller number, that is, 10 - 4 = 6.

Hope you can understand my solution...

You are welcome.

info … Primary 1 Maths onwards.


every 5 to 7 years, MOE may revise Maths curriculum.
from 2013 onwards, could be new changes to Maths curriculum methodology.

some schools in P1 - later part of the year, Term 4 onwards, pupils are taught ‘Bar Modeling’.

a powerful new concept newly introduced to schools, solve word problems.

why ? because it is visual !

when is visual, pupils can ‘see’. Pupils thus find easier to understand, grasp complex, abstract Maths concepts more confidently.

this is a new move invented recently – move away from the old, traditional ‘Algebra’ method of solving Maths, where pupils tend to get confused, lost, don’t know how to begin / solve, esp. if the question gets complicated.

to tackle word problems proficiently, 2 types of skill set are required nowadays (both English and Maths skills), from a child:-

i) the ability to read & comprehend the qn in English,
ii) the ability to interpret the figures given & then apply the correct Maths concept.

some schools have started.

may attend ‘Maths workshop for Parents on Maths Problem Solving, using the 'Model Method’, by Dr. Yeap Ban Har.

can download his powerpoint slides, print out in color.
Questions and answers are found together, inside his slides.

learn to help your child solve Maths problems, using 'Model' method.

first part of his workshop focus on the basic model.
second part focus on advanced skills needed for solving challenging problems.

1)\t Raffles Girls’ primary

only first question is P1 / P2.
the rest are higher level, P3 to P6:-

download powerpoint slides – before this web page blog spot gets refreshed. Once gone, each parent pay $30, attend the 3 hrs workshop. Furthermore, may wait a long time before the … next parents workshop is conducted again ?

if your child in kindergarten K2 now - download first, keep for future use. Slides come in useful, handy one day!

I thought the current math curriculum in school is using 'model' to solve word problems?? Model is not the same as 'Bar modelling'?? :?


Thanks for sharing the useful links to the various powerpoint slides.
:thankyou:

[bigsnoopy]

Bar modeling is something like graphs right?
