In 2nd grade we have been having some fun with the square.  The kids started by sharing what they know about the square in their journal.

We also looked at a logic puzzle called How Many Squares.  The kids had to count the squares, explain their strategy.  We then counted a second time to see if we could find even more.  Most kids found 16-24 their first time around, they were surprised to discover there were many more. 

This week we also looked at the magic that can happen when we fold a square in various ways…new polygons emerge.  The 2nd graders loved learning all of this new math terminology.

The students had the opportunity to use a protractor to the angles on various squares around the room.  They discovered that all squares have 90 degree angles.  This information helped them when they worked to write a program to create a square in Hopscotch.

Some 2nd graders took their square program to a new level.  They made it like a game.  You click on their character and a fact about a square appears.
