Lesson Seven: The Best Day
Seth is working on a multimedia presentation about the rainforest to play during the group’s bake sale. When Alex brings in a poster to publicize the sale, the MathTek kids find they need to use some problem-solving techniques to decide on the best day to hold the sale. A look at several types of data provided by Ms. Davis helps them decide what information they need. The group decides to make a bar graph using the number of people who used the library every day for one month. The group makes four separate graphs, one graph for each week. The interpretation of their graphs, as well as a discussion and investigation of chances and probability, helps the group choose what they predict will be the busiest day at the library to ensure the success of their bake sale.
