The Fraction Attraction is a great way to practice your estimation of fractions. Set the model to represent the fraction. The closer you get, the higher your accuracy. Slide the bar to set the bar and circle models. Click two of the dots to set the boundaries for the dot model. At the end of the game, you are given your final accuracy. Beat other Scratchers to get on the top 10 score board if you have the rights to set cloud variables. Be sure to check out my book of weekly 4th grade Scratch/math lessons. http://goo.gl/pHF6Hd
