Writing Open Sentences
Topic Index | Geometry Index | Regents Exam Prep Center

 

As an exercise in writing in the content area, ask students to create 10 open sentences.  This may be a homework assignment or a class activity. 

 The directions may include:

  • a directive that there must be 5 algebraic sentences.

  • a directive that there must be questions which reflect a particular unit of study.

  • a directive that there must be at least 2 questions pertaining to a hobby or interest.

  • a need for a designated domain for each question.

  • a request that the questions be placed on 3x5 cards.

  • a need for an answer key on a separate sheet of paper.

Arrange the students in groups (or pairs.)  Collect the cards from the students in each group along with the answer keys.  Distribute the cards to a different group -- keep the answer keys.
  (
Keep the cards and answer keys grouped together so that grading will be easier.)  

When the groups have decided upon their answers, you may collect the papers for grading or you may share the answer keys with the students and let them check their own work.
