## Reflection: Adjustments to Practice Gram to gram conversions - Section 6: Debrief

During this part of the unit I have had to work hard to help students with perseverance.  The two biggest challenges for my students are math deficits and remembering all of the details necessary for successful completion of a stoichiometry problem.  Next year, I plan to teach this lesson differently, because of these challenges.

I would like to spend a whole lesson re-teaching students how to multiply whole numbers and fractions together, and I would like to combine this lesson with a special focus on the cancellation of units that are found in the numerator and the denominator.

After I have done that, I would like to spend more time on each of the four steps that I taught for stoichiometry. I would like to create a quiz system, in which students would advance to the next step once they have mastered the previous step as evidenced by their quiz performance. These steps are balancing chemical equations, converting from gram to moles, using mole ratios, and converting from moles to grams. Once students are showing a 90% success rate with each of these steps, then they are ready to put them all together.

This process will hopefully help to identify students who need additional support, and will allow each student to proceed at their own pace through the unit. The quiz system, which I have used in the past, acts like a motivator for some students as well.
