This is my introductory lesson on finding percents for my 6th grade students. We use ratio tables to build the concept of finding percents. If you're not familiar with ratio tables and how you can use them to find percents, check out my YouTube video below:
Here's what's included:
-Guided Student Note Sheet
-Classwork Activity (Recording Sheet + Materials)
This is one of my favorite lessons and activities to do with students. Students are used to seeing percents on the top of graded papers, but for many, there is a lack of understanding on how the percent is determined. In this lesson students practice finding percents and discover how and why grade averages (among other things) are determined.
To do this, students will examine the papers of four siblings, each in a different grade. The siblings are arguing over who got the highest grade. Students must take the graded assignments (there's one they have to grade themselves!) and determine the percent score to see which sibling did the best. Students love pretending to be the teacher and finding the percents themselves!
One more note: The goal of a ratio table is to show equivalent ratios. I want my students to see that, for example, 85% = 85/100 = 0.85/1. Students will begin to see patterns as they solve percent problems. For example, they'll be able to mentally see that all percents are really just being multiplied by 0.01 (85%=0.85). It's these building blocks that let students develop a deeper understanding of percents, and lead towards "the standard" way of finding percents (just divide the part and whole, then multiply by 100). I highly encourage you to give them a shot!
