N Teaching GED at South Seattle CC · available for 1:1 & full-time

Dedicated to helping you pass the GED math test — and nothing else.

I'm Nick Cashion. I teach GED math at South Seattle Community College and build a free, complete GED math course on YouTube — in public, one lesson at a time. I tutor one-on-one in Seattle and nationwide over video, and I'm open to full-time instructor roles with programs that take this work as seriously as I do.

What's 47 × 6 — in your head?
01
47 → 50 round up
Start with a number you can see.
02
50 × 6 = 300
Easy one — just a 5 and a zero.
03
3 × 6 = 18 the 3 we added
Pay back what we borrowed.
04
300 − 18
Subtract — not multiply. This is the trick.
Final answer ?
— How Nick teaches every lesson. Not a trick. Actual number sense.

The way I teach

Most adult learners didn't fail math. Math instruction failed them. My job is to go back to the actual ground — numbers in your head before algorithms, plain English before vocabulary, one concept at a time — until it finally, genuinely, makes sense. That's how people pass the GED. That's the only way.

The Order of Operations

PEMDAS is a trap. 16 minutes, one concept, taught the way it actually needs to be taught — so it survives test day. If you're deciding whether my style works for you or your program, watch this one first.

Module 1 · Foundations

Mental Math & Arithmetic Fluency

Number sense before algorithms. Mental addition and subtraction before "mastering" the standard way. By the end of this module, you think with numbers — not just push symbols around.

About Nick

A Harvard-trained instructor in a community-college classroom — on purpose.

Portrait — to be added NC "We are gonna pass the GED."
Nick Cashion GED Math Guru
Seattle, WA Est. 2024

I'm Nick Cashion. I teach GED math at South Seattle Community College, and I'm building the full GED math curriculum on YouTube — free, one lesson at a time.

Before South Seattle, I worked with YouthCare Seattle — so I've been in the room with the exact learners adult-ed programs are built for: people juggling jobs, housing, families, and years of "I'm just not a math person" baggage. That story is almost always wrong. What actually happened is they got bad instruction at the wrong moment and never got it fixed.

My job is to fix it. Slow down, start at the actual ground, and rebuild number sense until the math finally makes sense — not the clever way, the real way.

I studied at Harvard, but the reason I'm in a community-college classroom is that this is the work I want to do. The most important math teaching in this country happens in adult-ed rooms, GED prep programs, and workforce development organizations. That's where I want to be — tutoring one-on-one, teaching classes, and building better free resources for everyone else's students too.

How I teach

Three principles. Visible in every lesson.

If you're hiring for an instructor role, or deciding whether to book tutoring, this is the shape of my teaching. You can verify each one on the YouTube channel today.

Principle 01

Number sense before procedure

My first lessons aren't algebra — they're mental addition and subtraction. Students learn to think with numbers before they see the standard algorithm. Tricks are forgettable; understanding isn't.

Principle 02

Build from the actual ground

I don't assume you "should already know" anything. The course starts at Lesson 1 with adding small numbers in your head — because for an adult learner who's been told they're "bad at math," that's the only honest place to start.

Principle 03

One concept per session, no fluff

Each lesson is 10–20 minutes on a single topic, taught the whole way through — not a 60-second trick that falls apart on test day. Tutoring sessions work the same way.

Work with me

Two ways this can go.

Short-term I'm taking new tutoring students. Long-term I'm looking for the right full-time instructor role. Both are serious; both are available right now.

Common questions

Good to know.

Do you tutor remotely, or only in person?+
Both. I work with students in person around Seattle, and remotely anywhere in the U.S. over video. Remote sessions are just as effective — I use a shared digital whiteboard so we can work problems together in real time.
How much do sessions cost?+
Rates depend on session length, frequency, and whether it's 1:1 or a small group. I'd rather talk through what you need before quoting a number — message me and I'll follow up with options within a day.
I'm terrified of math. Can you really help?+
Yes. Most of my students arrive convinced they're "bad at math." They're not — they just had bad math instruction. My whole job is to rebuild the foundation patiently, without judgment, until it makes sense. Watch a few lessons on the channel to see the style before you book.
Do you tutor the non-math sections of the GED too?+
Math is my specialty and where I add the most value. I can also help with the other GED sections — message me and I'll be straightforward about where I can help most.
How long will it take to pass?+
It depends on where you're starting. Some students are ready in 4–6 weeks; others need a few months. After a free intro call and a diagnostic practice test, I can give you a realistic, honest timeline — no false promises.
For programs: are you actually available for a full-time role?+
Yes. I'm currently teaching GED at South Seattle CC and actively open to expanded, full-time instructor roles with adult-education programs, community colleges, nonprofits, and workforce-development organizations. Open to Seattle-area in-person or remote-nationwide positions. Use the contact form and I'll send resume and references same-day.
Do you take students under 18?+
I primarily work with adult learners, but I'll take motivated 16+ students (GED age eligibility varies by state) as long as a parent or guardian is looped into scheduling and billing.
