Many of my students struggle with solving basic physics formula, and most of all, in understanding which units go with the answer to the question being asked.

**Is this familiar to you… The question ask for “HOW LONG does it take for the skateboarder to roll 25 meters while moving at 2 m/s?”,** **and the student answers 12.5 m/s!!!**

Students MIGHT use the right equation (time = speed/distance) , but the answer nearly **NEVER** has the right units – **the question is about time or distance and no matter what the student puts “m/s” as part of the answer!** Mind boggling to one degree, but this is all new for them and it’s normal to have trouble applying old skills to new problems.

**PROBLEM (nearly) SOLVED!**

The first formula is use in my 8th grade physics class is the equation for speed (or velocity). I have found that by guiding my students through the process of choosing the formula, writing the formula, and **forcing them to pay attention to the units** involved through this graphic organizer, greatly improves their success!

I also have created **DENSITY SQUARES** and I’m working on making resources for all of the formulas I use in my science classes.
