Reflection: Continuous Assessment Clean up before solving - Section 3: Closure


From experience I've learned that student mastery of handling like terms tends to fade quickly before it becomes automatic, especially with those students that are continuous strugglers in math. What I find that occurs most is students forgetting that unlike terms cannot be added or subtracted. It happens when engaged in other math problem calculations, where knowledge of "like" terms is not what is being assessed.

For example: A students is asked to state whether the following equation is an example of direct variation.  y + 1 = 3x 

The students goes forward and solves for y, wanting to rewrite the equation in y = kx form. 

y + 1 = 3x

    -1      -1

y = 2x

The student clearly forgot about not subtracting 3x - 1 

I suggest that for some time, questions on handling "like" terms be included in homework assignments, launch questions, or on worksheets to keep students busy when they finish classwork early, for example. This way they can be "kept on their toes" with like terms. 

  Students will forget about like terms.
  Continuous Assessment: Students will forget about like terms.
