There are lots of ideas you can use. You need to decide what kind of an
opener do you want? Do you want to pique interest in the topic of the day? Do
you want to review an idea? Do you want to bring in some history?  You
really don't want an opener that will take an entire class period unless you
are ready to teach that as the lesson. South-Western Publishing has a
pre-algebra book that has a "warm-up" activity for every lesson in the book.
Here are a couple of examples from the book.
Example 1: Use four 4's and any of the 4 basic operations, +,-,X,/. Find
expressions that equal 1, 2, 3, 4, and 5. The first one is done for you.
1=(4X4)/(4X4)

Example 2: Hand out a page or section of a newspaper or a magazine. Make a
list of the ways numbers are used.  (You can give a prize for the most on
the list, the most unique use of numbers....whatever!)

I do something called foursomes which can be used with just about anything.
The idea is which one of the four does NOT belong and why?

For example:   a) 1/2   b) 7/6   c) 6/8   d) 2/3
There can be more than one correct answer on these as long as the student
backs his/her answer up with a good reason.  One possible answer is 6/8 does
not belong because it is not in lowest terms.

Eisenhower National Clearinghouse at www.enc.org has lots of projects,
lessons and activities for you to choose from, so take a look there, too!
