Learning about minimum, maximum, and the middle (aka the median)

Author: kkruse  //  Category: Math, Uncategorized

The kids learned all about how to figure out the minimum, maximum, and middle of a set of data by measuring their head sizes and their arm spam.  They then had to get themselves in order from the minimum (smallest) to the maximum (largest) size.  The HUGE challenge was to do it without any talking.  This was challenging at first but they quickly got the hang of how to communicate about numbers without any words.  Once they were in order, I had them sit down starting with the minimum and the maximum, the next minimum and maximum, until we got to the median value.

Today we learned how to order fractions by their size and to find out if two fractions are equivalent.  We  hung  our fraction index cards on our “number line” and then checked out work.

Since I was home sick today I was playing on the computer and found this wonderful math web site.  I tried the tangram game and because I am so spatially challenged it took me forever to put together a simple 4 piece tangram.  I challenge you to see how you do!
