Common Core Math for Tutors

Your student struggles with fractions.
But which specific skill is the gap?

Common Core standards break math topics into specific, teachable skills. K12worX gives each skill its own slides and exercises — so you can target the exact gap in one session. Free, no account required.

The topic isn't the problem — finding the right skill is

"Fractions" isn't one thing to teach — it's six different skills. Your student only needs one. Here's what makes that hard:

You know the topic, but not the gap

A parent says their child struggles with "fractions." But fractions spans half a dozen specific skills — adding, subtracting, multiplying, dividing, converting, comparing. Which one is the actual gap? You need to narrow it down before you can teach it.

One hour, one shot

A teacher covers a topic over weeks. You have a single session. You can't afford to reteach the whole topic — you need to identify the specific skill gap and address it directly.

Materials are organized by chapter, not by skill

Textbooks bundle skills into chapters. Khan Academy organizes by topic. Neither lets you pull up teaching materials for one specific skill and practice it in isolation.

Searching takes longer than tutoring

Piecing together slides from one source, worksheets from another, and solutions from a third. By the time you've assembled materials for the right skill, the session is half over.

How it works

Start with the topic

Your student struggles with ratios, fractions, or negative numbers. Browse by grade and topic to see the specific skills within it.

Identify the skill gap

Each topic is broken into specific, teachable skills — mapped to Common Core standards. Find the one your student actually needs.

Teach and practice

Each skill has its own slides and exercises. Walk through the slides together, then practice with problems that have worked solutions.

Every slide deck is structured for teaching — concept introduction, worked examples, guided practice — not scraped from worksheets or auto-generated. Each exercise set targets one specific skill and includes worked solutions, so you can use them in a session with confidence.

Browsing and using content requires no account and collects no personal data. Premium features (coming soon) require a free account for tutors — no student accounts, no student data collected.

What makes this different

	K12worX	Khan Academy	Textbooks
Find the skill gap	Topic → specific skills, each one browsable	Topic-level — no breakdown by skill	Chapter-level — skills bundled together
Teach from it	Slides for one-on-one walkthroughs	Video — student watches, tutor waits	Pages — can't share without the book
Practice one skill	Exercises + worked solutions per skill	Exercises by topic, not by skill	Problem sets by chapter
Works across students	Same resource, any school's curriculum	Same resource, but no skill-level targeting	Tied to one school's adopted textbook

Coming soon: diagnosis, tracking, and session history

All content stays free. These premium features add tutor workflow tools — identify skill gaps, track mastery, and build a session history for each student.

Gap identification

See which skills a student hasn't covered or needs review — the starting point for every session.

Mastery tracking

Mark skills as introduced, practicing, or mastered. Know where each student stands at a glance.

Session log

Record which skills you covered in each session, with notes. The next session picks up where you left off.

Exercise grading

Students submit answers and get instant feedback. You see per-problem results without manual checking.
