4th grade math HELP---

[jennyf2]

My son brought his homework home tonight & for the first time I am stumped! I have googled & can't find a thing. I am certainly NOT smarter than a 4th grader Does anyone know what 3, 4, or 5 are?? I have never heard of them.

He has 4 multiplication & division problems that needs to find the answer (which he did) now he needs to figure out what category each word problem fits in to....


1:Array Multiplication
2:Array Division
3:Repeated Groups Multiplication
4:Repeated Groups Division with Unknown Multiplier (group size)
5:Repeated Groups Division with Unknown Group Size

HELP!!!!!!

Can you post one of the word problems, so I can see what it looks like?

 

[jennyf2]

Amelia wrote 2 pages in her journal every night. How many pages did she write each week?

---------------------

All the word problems are as basic. He wrote the equation & solved all the problems now he needs to decide what problem type they are?

Thanks for the response....

I'm very sorry. But i have no idea either. I thought that I did. But I guess that I'm not smarter than a 4th grader either.

I would say repeated groups multiplication. It isn't division so that eliminates 3 choices. You could use an array to solve that problem but I really doubt that is the answer.

http://www.homeschoolmath.net/teaching/md/multiplication-repeated-addition.php seems like a good explanation for that one.

4:Repeated Groups Division with Unknown Multiplier (group size)
Example: If the store sells 3 dogs a day, how many days will it take to sell all 12 dogs in the store?


5:Repeated Groups Division with Unknown Group Size

Example: A store has 12 dogs, how many dogs must the store sell each day, if it sells has the same number of dogs a day for 4 days.

I'm not sure if I can easily explain the arrays. Check youtube. There are some good examples of that on there. The arrays are a visual method so it lends itself to video on you tube.

This sounds like something from the Everyday Math series. I'd google that to see if you can get to that website.

The problem that you listed (Amelia & the journal pages) I think is the repeated multiplication type. If the problem has something like needing to add the same number (i.e. 2 in this problem), it shows multiplication through repeated addition.

For the division ones, I'm thinking that repeated division with unknown multiplier would be the division problem without the divisor. The repeated division without the group size would be the division problem with the dividend as the unknown.

Hopefully this helps & isn't totally wrong. Good luck to your son tomorrow!

It's repeated groups multiplication. 2 pages is the group repeated over a week (7 nights). Oh, the fun of homework!

 

[jennyf2]

Thanks for the responses & suggestions I called a few other parents & they were just as stumped as us & its only the 2nd week of school...

Yikes! I recently taught 4th grade for 4 years, and I don't know what that means! I know how to do repeated division, but I don't think that is your question.

 

[MickeyHereWeCome!]

My daughter says it is "repeated groups multiplication". She is in fourth grade.

I know what you mean about being stumped with some of these. Dd has been put in an advanced math group this year, so her work is much more difficult anyway. But this stuff is totally different from how we learned it and how I learned to teach (I've been out of the classroom for 12 years). She has more homework than my 7th grader! Ugh. It looks like we're all in for a touch year!

 

[Juliegirl1]

Good grief, I don't remember learning stuff like that when I was a kid. Is it me or does it seem like they almost make it harder to learn stuff these days? My poor child is probably going to have to be tutored because math was not my strong subject and I won't be able to help him. He just started fourth grade and so far I can still help him...

Math sure has changed since we were in school. I was so thankful I helped in the class during math when my daughter was in third grade. I would have been totally lost with all the new terms and programs and such. Our district uses Bridges math I am not sure if they could make it more confusing if they tried. There were times the teacher didn't even understand what she was supost to be doing and she had taught for over 25 years. Good luck, maybe you could ask the teacher if she could copy off the teachers instructions for you if it continues to be a problem, that may give you a little better idea of what they are doing, maybe.

That looks like Everyday Math. We have had trouble figuring out what they are looking for on homework too. If it is Everyday Math you can go to their website to see the parent letter, and homework help for each unit. There is a link for each unit.

What happened to the example problems at the top of worksheets?! When I was in school there were always two problems worked out in steps for us... It drives me crazy when the kids have homework, the instructions don't make sense and there is nothing to refer back to.

Have you thought of a quick call or email to your child's teacher?

One of the best ways to learn something is to teach it to someone else. Ask you child to play teacher and show you how complete one of her math problems.

 

[seashoreCM]

now he needs to figure out what category each word problem fits in to...

1:Array Multiplication
...

I have never heard of those terms. Was DS ever given an explanation of what the terms mean, to the point where he can describe the terms in English prior to inserting any math problems into the categories?

Off the top of my head I would write a note to the teacher asking what those terms mean.

By the way, at first glance "array multiplication" to me means "matrix multiplication" which I put in the "second year algebra" education level.

Am I the only one thinking that is is the child's homework, and if the child doesn't know the answer, then they'll just have to get it wrong ?? I really don't see me running to find the answers to my son's homework for him - I did enough homework when I was in school, I don't need to be doing any more at my age !

 

[rparmfamily]

Is it a worksheet? Does it say "Homelink" ?

 

[MickeyMinnieMom]

I know this doesn't help answer the question, but I can't help but thinking: What good will it do kids/anyone to know this??

Oh, my... with one in preschool and one in K, I am now afraid of what we'll face in a few years!

Hope your DS is able to crack this one... good luck!

I know if it's Everyday Math, they send home (or you can access online) the Family Letters, which are AWESOME at explaining exactly what your child is learning and how it's being taught. The concepts are often the same, the delivery is different.
