I played this game teachers vs. students with my classes to review using conversion factors in Algebra 1.
My rules were: Students choose the 1st or 2nd conversion factor by showing me that # of fingers in front of their chest. I would award points to myself if more students were wrong or to the class if more students got it right. Depending on how well you enforce silence and showing fingers in front of the chest, it may take several questions for them to get enough points to beat you! I awarded points for the conversion factors and then once we solved the problem that showed up, I chose random students. Wrong answers erased the point that was just earned.
Includes: 4 one-step conversions involving one unit to another
2 one-step conversions involving one rate to another
1 two-step conversion involving one rate to another (I gave 2 points here, one for each conversion factor)
Answers are including in the slides for the choice of conversion factor. Answers are in the notes for the conversion problems.
