I found that teaching demensional analysis was exteremely hard last year. Does anyone have any tips for next year?

Do you utilize the 'Railroad Track' method when teaching dimensional analysis? I have found that my students understand it better rather than setting them up as fractions, even though it is ultimately the same thing.

This domino game is a great hands-on activity to practice dimensional analysis. It is such an important concept in chemistry because stoichiometry is just fancy dimensional analysis ??

Another suggestion could be to see how the teachers in your math department teach dimensional analysis or unit conversions.  In math, they may approach it as multiplying fractions together instead of showing a grid.  Even though they are conceptually identical processes, students may not see them as such and not be able to transfer what they may know between the two courses.  The dominos are a good visual of showing how the fractions are being reduced between the numerator and denominator.  I like to teach it as fractions (I'm a math teacher) and sometimes students just don't understand.  However, when I show the grided approach like how my science department teaches the conversion side by side with the fraction, students respond with, 'Oh that's all I had to do?'

Hello Tim, my name is Annie Dietz. I am a preservice teacher at Wartburg College, studying to become a high school Biology teacher. In my class at Wartburg, we have been talking about how to collaborate with other teachers. You have an amazing point about collaborating with math teachers! In your opinion, what is the best way to ask for collaboration in teaching dimensional analysis from the math department?
