If I were hosting a professional development session with teachers on a useful activity for the classroom, I would first communicate that the goal of the lesson should be to communicate that data is information and information is context dependant. The activity would involve collecting data from students home such as how many pets and what kind of pets do students have. Next, students would use a Tally to organize the data. Finally, the Tally would be used to create a bar graph on the computers of all the different pets students have in their homes. Extension would include the presentation of data in the form of infographics and for students to identify patterns through repetition and write a summary of the data. For example, “as shown in through the data, dogs are the most popular pet in Room 3 followed by cats, etc.”
