Algebra II (4) Assessment Reflection #5

December 9, 2012

The latest Quadratics Quiz on material through Completing the Square had a average of 85% and a median of 90%.  We will have one more quiz before the vacation.

Let's look at some student work.

Below,  I've seen this from time to time.  Students ignore the parenthesis and do the wrong operation.
Below, lots of students wrote their names with exclamation marks!
Below, we cannot forget about the middle terms when expaning (a+b)(a+b).
Below, I want you to be able to draw rough sketches of equations. Make sure you know how to find x and y intercepts.
Below, this is a beautiful graph with all important information labelled clearly.

Below, nice job expanding, but 2/2 is not 2.

Below, plus or minus when solving by taking square roots is so important to remember.

Below, this student seems to do the problem in her head, but still knows to divide by the  coefficient of the linear term.  Nice work :).

Below,  when asked to find the roots, zeros, or x intercepts it all means the same thing.
This person needs to go one more step.

Below,  if you are just simplifying a radical, then you do not add the plus or minus.  That was the crux of the entire lesson.

Below,  let's get in the habit of simplifying expressions.

Below, and last but not least, this student make smile stressing the importance of the little "plus or minus" when SOLVING by taking square roots.

Please find my Assessment Data for the quiz below.  We'll review in class.

Raw Scores do not account for partial credit. The MCAS and SAT do not use partial credit.

My Best,
