Reflection: Debate Equations involving Factored Expressions - Section 2: Direct Instruction

 

My favorite part of this lesson was the last slide in the direct instruction.  The students really had some good conversations about whether they could set each part of this equation equal to 1.  As I mentioned in the narrative, several students ended up solving the equations and substituting to prove that it didn't work.  Others were not really convinced until a student came up to the board to show what she had done and why it did not work.  I was really impressed when another student reasoned that just because two numbers multiply to 1, it doesn't mean that they are both 1.  Many students in the class struggled to think of another example besides 1 and 1.  Then this student showed them that .5 x 2 is also equal to 1 along with several other examples.  This was one of those WOW moments.
