Time for GeoBoards and Rubber Bands

Today in class we got to use GeoBoards. I really enjoyed using this. They are so much fun if you know how to use it.  So before our teacher gave us the GeoBoards she told us what we are supposed to do with it. As if we were the children in the classroom. Usually after you give it to children they see rubber bands and start shooting them up and go crazy. She said if we say it before handing it out the GeoBoards the students will use it the correct way and nothing crazy will happen. This was very helpful to know. This is what a GeoBoard looks like and a fun way to use it.

After we had the GeoBoards we got 2 worksheets. One worksheet was just filled with shapes like the one you see here but just with one shape on each GeoBoard. The first thing we were supposed to do is find the perimeter units and the area units. You must be wondering how we did that. To find the perimeter units you usually count the number of dots that is on the rubber bands. To find the area units square you usually count the number of squares inside the figure.To find interior we usually find the number that is the inside that is empty and without rubber bands.Then we had to make 3 of our own figures on our Geoboards and write our perimeter, interior and area on the white board.

The second worksheet we got was about discovering Pick’s Theorem. This worksheet there was a fish which we used and we make it on our GeoBoard. Then we had a couple questions based on finally perimeter pins, interior pins, and area pins. The perimeter and area pins are the same we did in the other worksheet.   Can you see we have 2 interior pins on this figure? On the fish below there are only 2 of the dots are not with rubber bands.

I also found few links according to what grade level you are interested in. One is based on GeoBoards click here!!  The other one is also on measurements based on area. Click on this link for more information.
