Almost any project you assign your students can be shared with others around the world. Exchange correspondence during the project, compare your results with those of other classes, or simply tell about what you are doing. Older students in middle and high school can be valuable tutors for younger students. Whole classes can participate, or a student needing extra help can be assigned a peer tutor. You might also submit the e-mail address of a student who is excelling in your class and is interested in tutoring someone in need.
Classes can create math problems to exchange with other classes around the country or the world.
In turn, your students' keypals can send problems for your class to solve. Your students will be motivated to invent interesting, challenging, and creative word problems. To find ideas for math collaborations, Mel suggests that you browse existing Internet projects. Only the first names and the first initial of the last names of students should be used. Know your district's Internet use policy and follow it.
