Can someone help, please? P4 DS1 is struggling with mathematical patterns. If 60/15 = 4, how can I get him to see 60/1.5 = 40. Any, online games resources for this?


Thanks.

Thanks.

60x10/1.5x10=600/15, since 60/15=4, 4x10=40.

For most of this type question, encourage him to convert to integer first, then do division.

On a different note - to all posters.

My P4 DS (just started P4 here in the UK) is struggling on the P3 Challenging Maths (Sabdya Sundar EPH). Is this normal, I know it is a hard book, but should he not be on to the P4 book by now. Any advice appreciated.

Thanks

I thought ur boy can do one year advance with the help of tutoring. :?

I bought P4 book, I don't have P3 one.After reading ur post,I flipped through the book,I think now(as end of the year and do many problem sum qn in school) my son can do.but I never give any sum from this book.I kept this book aside as it consists of quite thinking qns.I tried some qn from Maths Olympaid by Terry Chew.My son didn't like to do.So I stopped.I only depend on Past year papers.My son doesn't have motivation or willingness to do challenging qns.He easily give up.

Pls help! tomorrow maths exam…

2 files and 3 pens cost $12.50.A pen cost 75cents less than a file.How much does a pen cost?
Thank you in advance.
I did as follows
cost of pen []
cost of file []+75cents
5u+$1.5=$12.50
5u=$11.50
u=$2.30
A pen costs $2.30.

Is it correct?
How to do by substitute method? My son told a method (his own invention),I can’t agree with him.

5u + $1.50 = $12.50
5u = $12.50 - $1.50 = $11

u = $2.20
