Reflection: Checks for Understanding Simplifying Expressions - What are like terms? - Section 2: Explore


The table challenge taught the students how important Mathematical Practice 6 is :)  Many tables incorrectly answered the first question, not taking into account that the 12 was really a -12.  The students thought I was being picky - but really, they need to realize now that the sign in front of a term matters, and it makes a big difference when you go to combine like terms! After the debacle and debate that was question 1, the rest of the questions went very smoothly, and the students seemed to get the hang of simplifying expressions.  I definitely think tomorrow's lesson will be beneficial, however, because they will have an entire block to just work on their fluency with the material.
