180- Day 5 Connecting methods for dividing fractions

First of all, I am still over-planning for my lessons.  I'm so used to planning for a 90 minute block instead of a 47 minute period.  I've been starting each class with Estimate180, which is fantastic!  Totally zero entry for the kids and fun!  It is turning out to be perfect for the beginning of class- takes just a few minutes so I can take attendance and maybe glance around for homework.  One class is just obsessed with Mr. Stadel though...they want to know where the pictures were taken, whether the picture is of his house/yard/etc, and one even asked if he was my brother :)

Today we did a little bit more exploring with dividing fractions and unit rate...worked on connecting the graphing method we did yesterday to the standard algorithm for dividing fractions.  I used 4 divided by 1/3 so we were doing a lot of circling of groups and they were happy for a more efficient method.

I've been using kind of an exit ticket in the INB each day...depending on where we get to it either ends the period or starts the next day.  Here's the example from today...I wanted students to summarize what they learned about unit rate and dividing fractions in order to compare two dripping buckets.  I had them use both the graphing method and the standard algorithm- from here they will be able to choose whatever method they find most efficient for any given problem.
