Week of October 21st

It was a short week in the Stingray classroom.  The students worked hard on their PowerPoint presentation on the evolution of their animal.  We invite parents, grandparents and special friends to come view our presentations on Friday, November 8th at 2:15.  The presentations are very impressive, so we hope you can join us!

The students also were very excited about a math activity we did this week called Diffy Squares (Difference Squares).  The students all drew a large square on their paper and labeled the 4 corners with numbers.  They then have to find the difference between the 2 corners and put it in the middle of that line segment, eventually making a new square with the differences between numbers on all 4 sides of the square.  Their goal is to get all 4 sides to equal 0, but to do this in as many steps are possible.  Below you can see 2 Diffy Squares.  The first one needed only 4 steps to get to 0, while the second one had 6 steps.  Two students completed 8 step Diffy Squares, so they are all trying to beat that. 

 

The students thought they were fun and interesting (and I thought they were a great way to practice subtraction!).  Here are some pictures of the students hard at work on their Diffy Squares.
