After being frustrated with my new textbook's approach to teaching 7th & 8th graders math, I began creating my own notes and assignments. This packet (Proportional Equations combined with my free product), Proportional Tables, and Proportional Graphs contain my notes and initial practice sheets for learning the fundamentals of Proportional Relationships. I personally become bored quite easily (I'm riddled with ADD), so I kind of understand many of our students. The notes and many of the assignments have a certain degree of ... insanity.
This packet originally contained notes on Proportional Equations and two practice assignments. However, I placed the first practice assignment in with the free product I'm offering.
Defining the input & output values
Using x & y to find the constant of proportionality
k = y/x
Using k to write the relationship's equation
y = kx
Using an equation to find the rate of change
Using the rate of change to find possible x & y values
There are some very small word-ish type problems in which the students will find the constant of proportionality and then write the equation. These problems will also begin to slightly nudge your students to start thinking a little more critically as they begin seeing proportional relationships from a few "out-of-the-box" perspectives.
Lastly, the notes here begin a running example that is continued through the Proportional Tables' notes and the Proportional Graphs' notes. The example involves the "hair" of a certain person.
