I am currently taking a couple of math eduation classes at CSULB and I was wondering if anyone have any thoughts, ideas and favorite demonstrations on how to teach factorization.

add on... factorization, place values....anything...i want to make a file of lesson plans based on mathematics so that one day i can actually use if for my class...thanks so much

Have you tried seaching the internet using your favorite search engine for something like "mathematics lesson plan*"?

yep i have but my professor wants me to get them from other teachers. i wish i can do that but the professor seems very strict about downloading from the internet. i guess he wants original lesson plans...

I use factor trees for prime factorization and factor rainbows for factorization. My students enjoy making the factor trees...I usually let them use their colored pencils to make the joining lines. I also found that they didn't leave out numbers if they were making factor rainbows because every number needed a partner. I also had all of the division rules posted in my room so they could work through the numbers to see which would be a factor.

It helps if you teach divisibility first. I usually have them make some kind of foldables project to record the rules for dividing by 2, 3, 4, 5, 6, 9, 10. http://mathforum.org/teachers/elem/3-5/

You might find additional ideas at www.mathforum.org. I am a Massachusetts based M.Ed. student just studying the teaching of math now, but my Prof is crazy about that website.
