How do I help students learn algebra?
Both parents and teachers write to Teacher2Teacher asking for help in teaching algebra. One writer put it like this:
"I would like to know if you could tell me how to make algebra easier and more fun."
Another letter suggests that algebra is a course that many students will need to complete in order to meet graduation requirements:
"In Florida, the class of 2001 is the first to graduate with an Algebra I requirement. We offer 4 ways for the requirement to be met in the high school."
Teacher2Teacher Associates and contributors in the Teachers' Lounge discussions have responded to these many letters suggesting a variety of methods. Somewhere in the suggestions will be ideas to help your student learn algebra.
T2T discussions about algebra techniques:
Activity to show (a+b)^2 = (a+b)(a+b)
I was wondering if there is any kind of activity to show that (a + b)^2 = (a + b) (a + b)? If you have any suggestions, please let me know. This activity is intended for a high school algebra class....view discussion>>

Reason for using "m" and "b" in y = mx + b
When graphing a line, we teach the students to look for the location of the slope and yintercept through the equation y=mx+b. Why is "m" used to represent slope and why is "b" used to represent yintercept?...view discussion>>
