I think group work can be a great method for any concept, as long as it is guided to allow the students a chance to discover a new concept and/or practice that concept. For multiplication of fractions, perhaps start with some visuals and word problems. Say using a pizza for example and having them figure out what half of a half of pizza is, then move on to one third of a half of pizza, etc so they can discover visually and conceptually what it means to do 1/2 x 1/2 or 1/3 x 1/2.

Hope that makes sense and is helpful!

I think visuals support the understanding of multiplication of fractions. Students can use graph paper with colored pencils or virtual manipulatives. (http://nlvm.usu.edu/en/nav/frames_asid_194_g_2_t_1.html?from=grade_g_2.html.) The visual allows them to see it...ie 1/2 x 2/3 means 1/2 of 2/3 which they will "see" as 2/6 or 1/3 once they color it.

Also, group work helps students learn with each other and tackle problems that might be too challenging alone. Consider giving them three fraction multiplication problems, two with the correct answers and one with an incorrect answer. Ask them to show visually or prove which ones are correct/incorrect.

I love fraction multiplication and love group work, with a nice mix of some individual think time embedded. Here is the project we did with Tch on 5th grade fraction multiplication task work:

Hope that help!
