P2 Math - General Discussion

[mrswongtuition]

For P2, a model would be clearer:


Sam wanted to buy 7 T shirts but was short of $14. He bought 6 T-shirts and was left with $9. The cost of each T-shirt is the same. What was the original amount of money does Sam have?

Sam's $: [---------------------------------------------------------------][14]
7 shirts : [--------][--------][--------][--------][--------][--------][--------]
6 shirts : [--------][--------][--------][--------][--------][--------][ 9 ]

Look carefully at the last unit (1 shirt), it is 14 + 9 = 23.

To find out how much he has, we need to find the cost of 6 shirts plus $9.
1 shirt = $23
6 shirts = 6 x $23= $138
Add the $9 left after buying 6 shirts = $138 + $9 = $147

thanks for the reply mrs wong, that is what we need to follow, the unit method.

Is this really P2 Maths ?? I thought it was too difficult for a P2 students. Where is the question found, assessment or from school ?

This should actually be P3 Maths as P2s have not learnt multiplication of 2d by 1d.


However, similar questions have been spotted in P2 Maths homework (with smaller numbers which they are able to multiply).

Wow. Maths question is getting more and more difficult now compare to two years ago. I remember at dd time, P1 (2006) to P3 (2008) were quite smooth except start from P4 then we need to monitor.

phew!
thought that i am alone to think that this is a bit too tough for P2 standard....

Actually this question is not difficult if they have learnt how to draw model diagram. P2 has learnt model diagram.

My son solved this question by applying the multiplication concept ie.

23 x 7 = 23 + 23 + 23 + 23 + 23 +23 +23
= 161
Ans: $161 - $14 = $147

i must be commenting from my own pov then...cos i am still very much stuck at the old-school math....that explains why i take a longer time to solve some of ds1's math questions.... sometimes, i don't even dare teach him in case i confuse him...:oops:
