  • The clinical interview: Do your students have a strong number sense, or do they rely on memorized procedures, floundering when faced with unfamiliar problems? A clinical interview can help you to assess how your students think about mathematics. This example interview provides a model.

    Activities

    The complete presentation is in PowerPoint format.

    1. First, the presentation gives 5 examples of monomials. You then ask your class to give 10 examples of monomials.
    2. The presentation then reviews examples of the Product of Powers. The students are then asked to give examples of the Product of Powers.
    3. The next screen deals with the Power of Powers. Ten examples of this rule is requested of the students. The students are then given 5 practice items to complete. The presentation introduces each practice item separately. The teacher may choose to work through these with the students.
    4. The next screen shows the problem and answer. The students are given some independent practice which tests the same practice problems to see how well they understood them.
    5. The next screen gives the answers to the test items.

    Assessment

    There is independent practice in the PowerPoint presentation. If you prefer, some textbook problems may be used as an assessment or an oral interview.

    Comments

    The presentation was a blast for my students and it caught every student’s interest. The sound effects were the “bomb.” I did this lesson in one of the master’s courses I took getting my administration degree. It wasn’t a lesson I had to come back to. I had to include the children’s work. I got an “A” from my students and my professor. I had a parent coming out to commend me for the presentation. She said her daughter was impressed.
