Hi ryankwek


This is the method I use.

1. 5 is 1 less than _
I teach my kids to close the number that comes before \"the less than\" or \"more than\". For this eg, he will need to close number 1. He will then read it as 5 is less than _____. If he understands concept more or less, he should know that the blank should be filled with bigger number. Since the answer must be a bigger number, he needs to add instead of minus.

2. _ is 1 less than 3
Close the number before the less than again. The question will read as what is less than 3. The blank must me a number smaller than 3. So must minues in order to get smaller number.

Hope this will help.

If the question is
1 less than 7 is _____
How could i teach with this method?
Also if the question is
8 is ___ more than 3.
will this method help?
I'm struggling with my dd now.
She is in p2 now. Can you help? Thank you.

There were 51 passengers in a bus. Some passengers alighted at the first bus stop. How many passengers alighted at the first bus stop if 39 passengers were left in the bus ?

51-39=12

maybe u can try replacing the word 'is' with the '=' sign. But your child must always remember when it comes to subtracting, always big number minus small number.


1. 5 is 1 less than _
5 = _ - 1
2. _ is 1 less than 3
_ = 3 - 1

1 less than 7 is _____
7 - 1 = _

8 is ___ more than 3.
8 = _ + 3

Hope my 'another' way helps u.

Hey! That’s how I teach my gal too! I told her 'is" and "=" is the same here. She seems to get it.

Thank you.

but if the case is
6 is ____ less than 7.
the sentence is :
6= 7- ____
i doubt whether she’ll be able to understand changing signs.
I am sure that your method works.
but how to explain this to my dd.
please give me some suggestion.

Actually this was my question originally posted on 5 Dec 2008 :
Are the teachers trying to test the students' English or Maths ?

The key to doing well in Maths, is actually not to be able to add or subtract like a calculator. It is more important to be very good in English in order to understand the question.

The worst case is if the Maths teacher cannot write in good English

P2Q: Alice has 380 red and yellow marbles.

110 marbles are yellow.
how many more red marbles than yellow marbles does she have?

Query:
i would like to ask, besides the ‘Part-Whole Model’ to find out the number of red marbles, do we still have to draw the "Comparison Model" to find out how many more red than yellow marbles?

TIA.

hmm my method of drawing is different. I will draw the comparison model.
But i will illustrate the total by a big curvy curve. maybe times have changed. are models given marks? otherwise i presume model to be drawn only to help you see the relationship.

Yesterday DS mention that the silencer reading on every Tuesday is on Maths. May I know what kind of books is that? Any recommendation?

Many thanks in advance.
