A key characteristic of successful mathematics teachers is that they are able to provide varied activities that promote student learning and assessment. Web 2.0 applications can provide an assortment of tools to help produce creative activities. A Web 2.0 tool enables the student to enter data and create multimedia products using text, graphics, audio, and video. The possibilities for creativity and variety are endless. The Standards for Mathematical Practice (SMP) in the Common Core State Standards include a strong emphasis on student reasoning and sense making and on demonstrations of understanding. In describing mathematical proficiency, these standards recommend that students should work collaboratively, explaining and discussing concepts to refine understanding. Students should model and apply their mathematics knowledge and use technological tools and communicate their understanding precisely. Web 2.0 tools can be useful in structuring a variety of learning experiences to enable the development of students' habits of practice, as recommended by the Standards for Mathematical Practice. For the activities in this article, students interact with the mathematics in a creative and collaborative context and communicate their understanding both individually and in groups while working on projects.
