Reflection: Checks for Understanding Re-Calling Pythagoras' Theorem - Section 4: Activity and Exit Ticket


At the end of today's class, we had 2-3 minutes left!  Wow, it doesn't happen often but when it does, I like to use this time to review important topics that we haven't reviewed in awhile.  Today, I wrote on the board two points and the words perpendicular bisector.  I then asked students to tell me how they could find the perpendicular bisector.  Students led the discussion by first suggesting that we find the bisector part using the midpoint.  Then, we reviewed how to show that two lines were perpendicular.  It was great to hear that my students remembered that perpendicular lines had negative reciprocals but then I asked them, "how do you know what to identify as negative reciprocals?"  We then were able to review slope!

It was a great use of time and helped them to review for upcoming mid-term!
