Q4 Abstraction: Examples

Step 2. Reflecting on the four examples you just reviewed, think about your real-world use of abstraction.  Jot down at least two of your examples and be ready to share with a partner or the class based on instructions from your teacher.

Step 3. Think about a fill-in-the-blank sentence.  If you were to have your classmates fill in the blanks, most likely you would get a wide range of answers.  So, the blank spaces are the hidden information. For example:  I have ______ blue ______.

• The sentence would have a common language with I, hand, and blue being the same in every sentence, but the blanks are the information that may be different for each person filling in the blanks.
• This same idea holds with computer science.  The person programming has to decide what to include and what to leave out based on choices the person using the program has to make.
