Introducing CommonMath

My kids are in elementary school. I watch them do math homework, and some nights it’s wonderful — they’re thinking, reasoning, building real understanding. Other nights it’s worksheets that feel like they were designed to make kids hate math. The difference almost always comes down to curriculum.

The problem

There is fantastic Open Education Resource content for math out there. Lessons aligned to standards, rich problem sets, visual models that actually help kids understand fractions instead of just memorizing procedures. But it’s scattered across dozens of sites, in different formats, with inconsistent quality. A teacher who wants to assemble a coherent year from OER materials is looking at hundreds of hours of work.

So most teachers don’t. They use whatever their district bought, even when they know it could be better.

What CommonMath is building

CommonMath takes the best OER materials and weaves them into a coherent, modern K-8 math curriculum. Complete scope and sequence. Lesson plans that connect to each other. Assessments that actually measure understanding. Free for teachers and families.

We’re not creating content from scratch — we’re curating, sequencing, and filling gaps in what already exists. The open education community has done incredible work. What’s missing is the connective tissue that turns a collection of good lessons into a curriculum you can actually teach.

Where AI fits in

This is where it gets interesting. AI can help us adapt materials for different learning levels, generate practice problems that target specific misconceptions, and build assessment items that go beyond “did they get the right answer” to “do they understand why.”

We’re not building an AI tutor. We’re using AI as a tool to help human teachers do what they already do well — but faster, with better resources, and with materials that meet every kid where they are.

Early days

CommonMath is in early development. We’re building in public and sharing progress as we go. If you’re a teacher, curriculum specialist, or just someone who cares about math education, I’d love to hear from you.

The best curriculum is built by the people who use it. Reach out at jeff@jumpstartlab.com.
