          This lesson was one of the first lessons that I developed with the SMART Board Interactive White Board.  In geometry, many thermos and postulates are given to our students but how many are truly learned.  To me, learning is best done through experience and discovery.  This lesson allows the students to self-discover the relationship between central angles and inscribed angles of a circle.  Every student’s work will be different, but their result will be the same, and together you can develop a formal statement about these angles. 

            Math three is a gallery dedicated to my students and one of my major philosophies of education: “If the students can play with it on their desks’, then I must be able to play with on the SMART Board.  In the state of Ohio, there are math content standards.  It was obvious that the SMART Board, through SMART Notebook, could handle every one of those content standards until it got to geometry constructions.  This racked my brain.  Finally it hit me.  I created a circle with the ellipse feature and a 10 x 10 grid.  I added a red dot for the center, removed the grid and grouped the circle and dot together.   I then drew a thick white mark over the black circle, creating a white-out.  Now, only the red dot shows if the background of my notebook file is white.  I can then use the “erase” feature, “clone” feature, and “order” feature to show different sections of the circle, thus creating an arc like a compass.  Now I can use this for any construction problem that I may need to teach, and if I change my background, I can change the white-out to the same color.  Have Fun!

One day I was wondering why students could not add by seeing the relationship to numbers.  I thought hard about what happened in my life that gave me that skill.  Yahtzee came to mind.  I would play Yahtzee all the time and as a result I gained many mathematical skills.  Such as:

Below you will find the playing board.  Careful…I have changed some of the lower section.  The strategy from regular Yahtzee has changed.  Feel free to use the game board and change the numbers if you are working with younger students and just want to use the color recognition.  Also is a PDF file which sometimes seems to download and print faster, however it is not changeable.  Lastly is a Microsoft Word Document associated with the Avery Labels #8167.  Use that document to print your own stickers for a regular size dice.  Have Fun!
