I used Prezi and the word cloud generator Tagxedo.
Students get so used to the flipcharts that it is great to mix things up from time to time. Having a prezi of information will grab the students attention by the motions incorporated There are also some great prezis that are public that I can use to show my students. The link below is a prezi that I found after searching 'Fractions'.
I prefer Tagxedo because you have more options when it comes to editing and you can make the clouds into different shapes. In the classroom, I crated a Tagxedo for my website that incorporated the classroom expectations the students had come up with from the online survey.
Both of these Tools are helpful because they grab the students' attention.
