P2 Math - General Discussion

[plum-cake]

Hi Janet,


Moon + Moon = 10
Star + Moon =15

Star = _____

this question is actually under the topic number bond :oops:

but our grown up minds always go for the short cuts and temp to divide it. Rather than going for number bonds.

Plum cake, thanks.

Hi plum-cake,

Met daughter's teacher yesterday when we went to pick her.
Her FT very concerned about number bonds which my daughter seems to be weak in. I feel rather stretched at both ends now - P1 and P5.

Hi Janet,

Pay more attention to your p5.
For your p1, she needs more practice on addition and subtraction.
because number bonds are the relationship between the whole number and the parts which makes that whole number.
Ex. take 10 as a whole number the parts which makes that whole number are (2,8) (4,6) (3,7) (5,5) (0,10) etc etc.

to practice these you can write Qs
10 = 8 + ___

Thanks for your tips. Will revise with her.

there are number bond word problems. ex in Fan- math process skills i-Excel level one,page 2 first 3 questions.

you can see more explenation in this

Hi plum cake,

Thanks so much for sharing the link. :lol:

How did your DD go with her first CA1 maths paper? Hope she did well. DD2 lost marks for her last problem sum. It requires 4 steps to solve the question and she missed out on the last step because she forgot to add one part of her model.....so careless.

Hi Tinkerbelle,

Thank you for asking me. Thats really better than mine. she lost 9 marks out of 50. Last part she did well only missing one of the number sentence. and lost 1 1/2 marks :roll: But in part A and B lots of careless mistakes. Its looks like she was in the dream land. In the working area she did correctly and put the wrong number(MCQ) in the ans. another mistake is writing in wrods. Ex. given numb is 204 she wrote Two hundred and four four. :x

I cant help her with these, we practiced more on word problems this time. so she did well in that part.

Hi plum-cake,
Your DD did well overall. :rahrah: Carelessness seems to be a common problem with kids. With practice, kids can usually overcome this. DD1 was like that when she was in P1/P2...either transfer the wrong answer or careless calculations. After lots of practice and reinforcement, she managed to change her habit and is not making too many careless mistakes these days. I'm sure your DD will overcome her carelessless. :lol:

Hi Janet,
I know how you feel about being stretched....my DDs are in P6 & P2 and preparing both of them for CA1 was a real challenge. Sometimes, I tend to give priority to DD1 as she's sitting for her PSLE this year & her work is much harder now. Feel guity sometimes as DD2 tends to be left to fend for herself.

As for number bonds, I agree with plum-cake.....keep practising addition & subtraction with your DD and I'm sure it'll become second nature to her. I used to buy those counting beads (those with 10 rows of colourful beads on a panel) and play number bond games with DD2. I would push 3 beads to one end and ask DD how many more beads would we need to \"pair up\" with 3 to make 10 beads etc. DD 2 found it easier to relate it than abstarct numbers.

Its Numberbond. Take this in your mind \" number bonds are the relationship between the whole number and the parts which makes that whole number\"

So in your question the whole number is 10. Because May have 10 cookies. Now you must think all the combinations which make 10. Because we needs the parts which makes that whole number. That is
0 + 10
1 + 9
2 + 8
3 + 7
4 + 6
5 + 5

But plate X is having 2 more than plate Y. so which pair is having 2 more than the other. 4, 6.
Therefore X = 6 and Y = 4

Oh, reading this thread really puts me back on track again :lol: DD2 will be P1 next year and I guess me have to start digging out all the old notes and start my revision again before guiding her
