The M in STEM comes alive when students experience hands-on, minds-on, learning that expects them to engage, explore, explain, elaborate, evaluate and create! We usually think of how mathematics is used in a STEM classroom, but how can a math classroom look at phenomena, emphasize questioning, inquiry, creative and critical thinking, while giving students the opportunity to use technology, apply engineering design, and problem solve around scientific phenomena to better understand rigorous and relevant mathematics? Attendees will participate in an action-oriented math workshop which will feature mini-lesson presentations, discussion, demonstration, hands-on activities, and problem solving around phenomena. The emphasis will be on doing rather than listening to - or about - science, technology, engineering and mathematics.
