For large classes, it tends to take out a lot of precious minutes during class to figure out groups. You could use technology, or use these Desk Group Organizers that do all the work for you! They include different shapes, colors, and French accents that can help you easily organize groups without picking Popsicle sticks! Simply laminate the images, cut them out, and tape them on each desk or space. Each day you can decide whether they should get into their "color" groups, "Shape" groups, or "accent" groups. These can double as well as an activity for elementary level French classes. " Les triangles... levez la main!" "Je suis un accent avec le son 'ay'!"....etc. There are enough here for a class as large as 29 students, or you can simply divvy it up based on your own class size. These can also be altered to any other language; simply switch the accent, or create your own category! Enjoy!
