This independent project by Tim Psaradelis invites middle school learners to explore mathematics through science, nature, and technology. Start with the story, choose a task, and record your reasoning on paper or in your math binder.
Course labels suggest an entry point; choose with your teacher based on what you already know. Sources and classroom assumptions are identified within each investigation. This first collection includes archived discoveries and lasting explorations; it is not a live news feed.
