In mathematics, the rule of three is the method of finding the fourth term of a mathematical proportion when the first three terms are known, that is, where the first term is in proportion to the second as the third is to the unknown fourth term.

To find the fourth term, multiply the second and third terms, then divide their product by the first term.

I am a 4th grade teacher and I am trying to find various ways to teach my students how to measure angles.

I am going to use this this summer to prepare me to tutor my son, whose class last year was woefully behind the state objectives. I am using a 4th grade textbook, but dn`t have an instructor`s manual, nor a whole lot of knowledge of the concepts. This has already helped me a great deal!

Yes, I am going to try to help my rising 4th grader with extra math work this summer.

Its explained very nicely and the lessons are not taught too quickly! I hope that this site can be of a great help to me and I am hoping that it helps me excel, catch up with all of the other smart ass students and achieve better grades on my tests, that I barely just pass by :) I need help with cross multiplication and also word/ratio problems...

I think it will help my 4th grader tremendously.
