Make a Systematic List  - organize the information

 

The Make a List strategy may be appropriate when:

          A list of data is given

          Data can easily be generated

          A sequence or series of numbers is involved

          Listing special cases helps you deal with complex problems

          You are asked to make a prediction or generalization

          Information can easily be organized and presented

          Listing the results obtain by using Guess and Check

          Asking “in how many ways” something can be done

          Trying to learn about a collection of numbers generated by a rule or formula

 

There is often more than one correct method of devising systematic lists.

 

Making the list SYSTEMATIC is extremely important.

Try to exhaust ALL possibilities as the list is created.
