Day 40: Nguyening Them Over

Today's question:

The responses I got back fell into two categories: Students who think math is boring and those who love my class.

My favorite one:

Mirror, Mirror, on the wall,
Who's the mathiest of them all?  I AM! 

I love math, I want more!

Just like that, a problem's done!

How great is that!  I think I want to do this again later in the year and see how the responses have changed.

In the geometry class, we went over the guided notes for a section dealing with postulates.  After we finished it, we completed our trials for The Lady and The Tiger.  I am pleased to say that no one was eaten by tigers!

The paperwork for that would be awful.

Then Pre-algebra.  After going over the warm-up and answering questions about the homework, I started talking about adding unlike fractions.  When I talked about division of fractions, I took a page from Fawn and used the method of rectangles.  As is my wont, I didn't think through the lesson all that well, but I loved the concept and wanted to do it again.

So today, I did!

I used the same basic method as division:

1/3 + 3/4

Draw two boxes that are 3x4.  Shade 1/3 of the first and 3/4 of the second (going down rows/columns).  Each of those boxes is a rectangular pizza cut into the same number of slices.  How many pieces did you eat total?(numerator)  How many slices in a pizza?(demoninator)

The kids who normally get lost picked it up VERY quickly and were excited to try it on their own. (Including a student who hasn't done much of anything all year.  This lit his fire!)

In sad news, the marking period is ending and people are going to start realizing that I haven't been grading anything.  I'm going to have to come up with an assessment for the last two chapters...

I hate to ruin good learning with grades.  It changes the motivation from intrinsic to extrinsic.

Also, I began experimenting with letting kids go to the bathroom between classes, provided they come back on time.  I will start keeping a list of kids who are late and they will lose the privilege of going.


  1. Really like your adding fractions idea. Very visual so they can actually see what's happening rather than just learn a rule.

    1. I wish I could take credit for it! I'll be doing more practice with it today. I'll let you know how it goes!
