破壞分數! (又稱解有分數的代數方程式)

學習代數並想知道如何用分數解方程式?打倒他們!來學習如何應用等式的性質,使解帶分數的方程式與解不帶分數的方程式一樣簡單。

課堂經歷

In this class, we will learn how to solve equations that have one or more fractions. Learners will discover how to "bust fractions" -- eliminating them so that they can simplify the equation. Through guided discovery, learners will learn how to bust fractions and then apply this skill to a variety of problems involving both one fraction, multiple fractions with the same denominator, multiple fractions with different denominators, and equations where the variable is in the denominator. 

Learners who are a good fit for this class are ones who already know how to solve two-step equations (ex: -3x + 8 = -16) and those with variables on both sides (ex: 4x - 7 = -6x +12). Learners should also know how to solve basic proportions (ex: x+2/15 = 90/3)

教師專業知識和證書
I have been teaching since 2006 and my specialties are Pre-Algebra, Algebra and Geometry.  Although I have been focusing on math education for the majority of my time as a teacher, I started my career in the sciences. I have a biology degree from Macalester College and as an undergraduate I did invertebrate zoology research at the Smithsonian National Museum of Natural History in Washington, DC. 

I started my teaching career as a middle school (grades 5-8) science teacher.  While I was in New York earning my master’s degree in Middle School General Education from the progressive school of education, Bank Street CoIlege, I took a course in inquiry-based pedagogical methods for teaching math. Suddenly, seeing math from this new perspective, I fell in love with mathematics and truly learned to appreciate it myself. 

Over the years, I have taught in several schools using methods that move from concrete to abstract. I have sought out positions at schools that encourage and reinforce this kind of pedagogy -- including two adolescent Montessori programs and one school specializing in inquiry education. I have enjoyed using hands-on curriculum with my learners and I am excited to adapt my favorite lessons to the Outschool platform.  

Some special pedagogical interests of mine: 
Numerical Fluency
Math Manipulatives: Algebra Tiles, Montessori materials, etc
Geometric Construction
Mathematical Exploration, Investigation, and Inquiry
Spatial Reasoning
Logic Puzzles


I only teach subjects that I truly love. That is what I love about teaching on Outschool -- I can truly bring this platform the best of what I have to offer. 

It sometimes interests my students to know that I didn't like math as a kid -- I actually got in trouble in 3rd grade for writing "I hate math" all over my math notebook. This is usually a huge surprise to my students, who know me as a total math nerd. I have a Ms. Frizzle style of fashion -- I have math and science prints and designs on my shoes, my dresses, my sweaters, and jewelry. I love solving a problem and helping my students develop that same curiosity and mindset. 

A note about scheduling: 
I move things around a lot. If you see a class you want to take, register for it as soon as it makes sense for your family to do so. Classes that have nobody in them are always subject to shifts and cancellations. Once at least one person is in a class, I don’t move or cancel it  (except in case of illness, emergency, etc of course). ☺️
