my son is in grade 4 and gets confused with whether the word problem is asking him to multiply or divide? What is the best way he can differentiate? Are there any tips or tricks, or tecniques. I am unable to xplain 2 him.

10 divided by 2 = 5
10 multiplied by 2 = 20
10 divided by 1/2 = 10/1 divided by 1/2
= 10/1 x 2/1 = 20
10 multiplied by 1/2 = 10/1 multiplied by 1/2
= 10/2 = 5

My math teacher explained it to me in a way that made sense. You have to translate the words to math language.
There are certain key words that mean different things,
Equals key words- is, are, was, were, will begives, yields
sold for
Addition-increased by
more than
combined, together
total of
sum
added to
Subtraction- decreased by
minus, less
difference between/of
less than, fewer than
Multiplication-of
times, multiplied by
product of
Division- per, a
out of
ratio of, quotient of
percent (divide by 100)
Hope this helps!

Look for some key words
Divide: quotient, split among, shared an amount equally, etc. Multiply: product, times, #of sets of #each, $ per hour worked, etc.
(look through some of his problems and make a list of the most common words used)
Try asking his teacher if she has a list of words that are commonly used in 4th grade. (I teach high school, so I don't know what 4th graders are expected to do)

hmmm...it would depend on the problem, but i'll try my best 2 explain.
whenever he has to divide, the problem will usually ask him to split something up into groups. (for example, if u have six pieces of candy, how can you divide them equally among three people).
whenever he has to multiply, he is doing the opposite and making a quantity bigger (for example, if u have 30 for a test average, how many times more than that do you need to get your grade up to a 90).

5 divided by 4. (to see how much you paid for them) then divide 5 by 3 to see how much you plan to charge then after you have those answers you subtract them (1.67-1.25) to see how much you made off of that card (42 cents per card OR .42) Then 100 divided by .42 I hope that's right.

Not much in my case. I hated those dang things back in the 70's. I guess we relate boring word problems into things we could relate to for easier understanding.

If it says product that is multiplication. ie the product of 4&5 is 20.

An example would make it easier to help explain. Do you have a word problem to give us?

if it talks about groups or dividing things up it is probably tlkin about division and if it talks about something increasing in size then its probably multiplacation...if this wont help then ask his teacher c:
