Arrays of chairs |
2009-01-08 |
|
Vickie pose la question :
I am not sure how to help my son figure out one of his math journal problems.
He is in third grade and this just seems a bit much for him.
They have only been working on multiplication for about 3 weeks
and just went back to school from Christmas break.
Their other homework has been about arrays,
so I guess his teacher wants this answered in some sort of array.
Unfortunately I'm not sure.
The problem states: If you have 24 chairs find the total number
of ways the chairs can be arranged.

Susan pose la question :
Hi, I'm taking over tutoring my 15 yr old niece, who has dyslexia.
She has been being tutored by someone else,but my sister had problems
with her. My niece needs help in math and english and spelling.
Is there a test that I can do with her to see where she stands at this point?
I do believe the math is at a 3rd, or 4th grade level. I'm not sure about the
other two. Do you have any suggestions? All help is appreciated.
