Greetings!
I am a math teacher at a public high school in Chicago (home of Local 399). I am trying to incorporate more hands on practical processes into my classroom. In our trigonometry unit we always use simple diagrams with side lengths and angles to introduce the basics of trig. However, I want to push beyond the simple examples and show my students the more complicated (and in my opinion more interesting) situations where angles are used "in real life."
To that end, I have been introducing students to various trade tools used for measurement. The one that I haven't been able to get my hands on yet is a theodolite or total station (for obvious cost reasons). I made my own crude theodolite using a multipurpose angle measurer from Harbor Freight but that's just a $6 piece of plastic and incredibly inaccurate.
Do y'all have any recommendations for an entry level theodolite and tripod? or are there any Local 399 members that would be able to help me out in the city? I can do a Donors Choose fundraiser to make up the cost if needed.
I'm basically looking for general advice regarding practical angle and distance measurement. What tools do you think I should procure so my students can be familiar with the real world application of measurement and are there decent ones that cost less than several grand?
Thank you!
