Individual activities can be classified in several ways. After reviewing the available activities,
I settled on five (numbers for the individual activities are in brackets):
1. Basic Idea Generation (Chapter 4) require relatively little effort. An example would be asking a friend for an idea (Brain Borrow [2]).
2. Related and Unrelated Stimuli (Chapter 5) generate ideas by providing some sort of stimulus to play against. Such stimuli might be related directly to a problem or unrelated. Examples of related stimuli would be using the elements of a fund-raising campaign to solicit money for your nonprofit organization by using activities such as
Bi-Wordal [22] or Combo Chatter [24]), both of which rely on words related to the problem. For the same problem, you also might play off of (free associate from) unrelated stimuli, such as unrelated pictures (for example, Picture Tickler [17]), words (PICLed Brains [16]), and objects (Tickler Things [21]), and see what ideas result.
3. Combinations (Chapter 6) blend or compare different problem elements and use the combinations and juxtapositions of elements to prompt ideas. Examples include Combo Chatter [24], Noun Action [28], and Parts Is Parts [30].
4. Free Association Activities (Chapter 7) rely on each previous idea triggering a subsequent idea to stimulate creative thinking. An example would be using the words “What if?” to help inspire ideas (What if. . . ? [49]). Or you might rely on exaggeration (Exaggerate That [39]) to help stretch thinking.
5. Miscellaneous Activities (Chapter 
represent two types of activities: backward and just alike only different. Backward activities reverse some aspect of a problem to produce a different perspective and, it is hoped, new ideas. Thus, a group might reverse assumptions about a problem (Turn Around [52]) and use the reversals as stimulators. Just alike only different procedures use analogies to generate ideas. Two examples are Bionic Ideas [53] and Chain Alike [54].
