Opportunities, opportunities, all these new tools. How do I use these tools to help my students grasp math concepts in a "hands-on" class? I am leaning towards using Squeak to highlight aspects of the surveying and site layout unit. Maybe a problem that has the students project layout points using Squeak then going out with the surveying equipment and confirming their answers or the other way around. Make preliminary measurements with the equipment then use the data to complete a Squeak exercise? The next step is creating some problems to see which way may fit the best. Opportunities, opportunities!
