Reflection: Vertical Alignment Percentage Equations - Section 1: Think About It


In this unit, I don't teach students to cross multiply.  In the 6th grade, students need to build a conceptual understanding of ratio relationships.  In the 7th grade, students build on this and expand their understanding of proportionality.  I also wait on showing students how to convert a percent into a decimal and multiply; first, I want them really internalizing the idea that percent is a special ratio out of 100.
