Product Description

Teaching how to balance equations can be both daunting and satisfying.

I have found that using the inventory method for balancing equations is what works best. Here are three practice worksheets for either your MS-PS1-5 or HS-PS1-7 unit, with six equations on each page.

My students have digital notebooks on Google Slides so I send these to them as an image to load in either Notability or Keynote so they can write on them. (They later take a screen shot to add to their slides). They do the initial inventory in one color and then, as they try coefficients, they cross the amounts out in another color so that they can see the process from beginning to end. They can also be printed to use with colored pencils.

I find that preparation before actually balancing is critically important so I use my product on analyzing molecules first and then my product on diagramming chemical equations and conservation of matter. It is essential that they have a thorough understanding of subscripts, coefficients and how to “dissect” a molecule before they begin the task of balancing.

DIAGRAMMING CHEMICAL EQUATIONS- PREPARATION FOR BALANCING MS-PS1-1 Conservation

I introduce this for the first time in six grade and then do it extensively in eighth grade. I have had many students come back and thank me in high school for insisting on making them do it! Balancing equations is important for chemistry, of course, but it also encourages logical, organized thinking.
