  Throughout our blog assignment in this course, we decided to stay within the realm of quadratic functions and their applications.   The three vocabulary words we selected were parabola, factoring, and projectile.   We selected parabola because it is one of the more unique and specialized words in this unit, and it is generally a brand new vocabulary word for students.   It is a crucial piece of quadratics and understanding this word will be very important down the line.   Factoring is another word we chose, mostly because of confusion that can surround this word.   I have noticed a lot of students are somewhat familiar with what a “factor” is, but get confused when they hear the word “factoring.”   This word could benefit from some further study to help break down this confusion for students and solidify their understanding.   Similar to factoring, projectile motion is generally somewhat familiar to students, but they lack a more detailed under...

One again, we elected to stay within the realm of quadratic functions due to the increased importance in real life and in future low and high-level mathematics courses following Algebra 1.   This article focuses on another...
