Fractions, Decimals, Percents: Math Center Activities and Guided Math Lessons
Here is a great packet of fraction activities that you can do in a guided math group and then put in math centers. Often I will play games in guided math groups with students until I am certain that they fully understand the concepts and then I will put the games into math centers so that they can practice. The new Common Core Math Standards focus on building a conceptual understanding of fractions in grades 3-5. Students are expected to illustrate fractions to explain their thinking, so a variety of encounters working with fractions is necessary to build background knowledge. You also really want to work in small guided math groups because this gives students an opportunity to talk out their thinking and intensely listen to others and explain what they have said.
