Dr. Angle Cure for Central and Inscribed Angles 

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 selfdiscover 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.

This lesson is one of the newest creations that I have developed. For this lesson you will need to save the image of the “White Circle” to a gallery, or download my math three gallery from my website. (http://www.ahs.stark.k12.oh.us/Math/Gensburg/SMARTBUGS.htm#Galleries) 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 whiteout. 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 whiteout to the same color. Have Fun!

Geometry Yahtzee: Created by Bret Gensburg 

This lesson is not yet useable for the SMART Board, but I hope to one day have a flash gallery that will allow learners to play this Geometry Yahtzee Game on the SMART Board. 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: 

I have taken the game of Yahtzee and added a twist. By making the sides of the dice different colors and polygons, more skills can be added to the list above. Color allows the game to be played on all grade levels, and the shapes give the students another opportunity to work with the names of polygons. 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!
