This file is a variety of circles split into different fractional pieces identified as decimals. I use this in my classroom as a group set of manipulatives. I use the decimal circles along with the fraction and percent circles to help teach equivalency and conversions. A good idea is to print cut out and laminate for a group set, I keep one set on my dry erase board I simply attached magnet buttons to the back of each laminated fractional piece. Enjoy!
