Class Experience

US Grade 8 - 11
This self-paced class is part 2 of a series that helps high school students feel whole in their math studies again - by revisiting commonly misunderstood math concepts that often continue to “haunt” those who are still confused by them 😵‍💫

👋 Hi there!  I’m Ms. Ava, and if you haven’t watched the introduction video for this class yet, please do so 👆first, and then continue reading…

🧮 ABOUT THIS CLASS: 🧮

This class helps students feel more comfortable with calculating integer operations mentally and learn tactics for catching their own computational errors, through a deep dive into prime numbers, divisibility rules, and algebraic LCM & GCF.

It consists of 4 video lessons that are all between 12-25 mins each, totaling 1hr and 13mins, and the accompanying practice problem sets, which should take approximately 10-20 mins to complete each.  In all, the course should take 1.5-2.5 hours for students to complete.

 🧮 CLASS STRUCTURE: 🧮

The structure of the class is fairly standard:  For each of the 4 video lessons, students watch the video tutorial, and then do the set of practice problems for that lesson.  They can then check their answers using the answer key.  

Although there are no live meetings for this class, I do respond to student comments and questions in the classroom.

 🧮 WHAT IS “SECOND-HAND” LEARNING? 🧮

The video lessons in this course are all in a format that I describe as “second-hand learning,” in which students learn by watching somebody else learn the concepts that they themselves need to learn.   

Each lesson resembles a tutoring session between me and a “thoroughly researched” character I made up, named Calculina, who plays the role of my student.

This format is ideal for students who feel uncomfortable or anxious when learning Math, as it takes the pressure off them, and they get to learn simply by observing somebody else making the types of mistakes that they would have made, or asking the questions that they may have been too afraid to ask. 

It also works very well for students with neurodivergent needs.

👩‍🏫 TEACHING STYLE AND QUALIFICATIONS: 👩‍🏫

My teaching style is something I’d describe as empathic, knowledgeable and flexible.  This means that when I work with students, I try to prioritize understanding their POV and guiding them to the right answers, rather than expecting them to keep up with me. 

I have a Bachelor's in Math, and 14 years of experience tutoring in practically all topics covered in traditional high school Math classes, including Pre-Algebra, Algebra, Geometry, Algebra 2, Pre-calculus, and Calculus.

Teacher expertise and credentials
Hi there, welcome to my Outschool page!  I’m Ms. Ava, and I help students bring their “A-game” in Math through tutoring and mindset coaching.  In my 14 years as a private tutor, I’ve helped hundreds of students, from 3rd grade and up, succeed in Math, regardless of their starting point.  

My teaching style is something I’d describe as empathic, knowledgeable, and flexible.  This means that when I work with students, I try to prioritize understanding their POV and guiding them to the right answers, rather than expecting them to keep up with me.  I've found this approach helps establish a trusting and cooperative dynamic with students, which allows for high productivity in our sessions.

I help students with:
- Elementary & Middle School Math
- Pre-Algebra
- Algebra 1 & 2
- Geometry
- Pre-Calculus
- Calculus
- General Academic Tutoring
- ACT/SAT Test Prep
- Mindset coaching
