You will need to make circles and fractions of those circles from felt. You can use the Circle Fractions download
as a good reference point. You will also need a large piece of felt to place on the bulletin board. Draw several circles on the board using magic marker, making sure that the circles are the same size as the felt pieces. Make a problem sheet with fractions that your students will need to show; for example, if you write 1/2, your students will need to show this by placing the half-circle felt piece onto the full circle outline that you made on the bulletin board. You can do any fractions up to three, or the number of circle outlines you wish to use, i.e. for 2-1/2 they would need two full felt circles filling in two outline circles, and one felt half-circle on the third outline. You can also make this into an addition-and-subtractions of fractions activity by adding plus (+) and/or minus (-) signs as well as an equal (=) sign. Of course, you will also need more circles and felt materials!
