Integrated Math

An alternative high school math sequence — Math 1, 2, and 3 — that interleaves algebra, geometry, statistics, and trig across three years instead of teaching them as separate courses. Used in some US states (notably California districts), most international curricula, and a growing number of homeschool programs. Same destination as the traditional sequence, different path.

What is Integrated Math?

Integrated Math (often labeled Math 1, Math 2, Math 3, or IM1-3) is a way of organizing the same high school math content as the traditional Algebra 1 — Geometry — Algebra 2 sequence, but threaded together instead of taught as separate subjects. In a typical year a student might do some linear algebra, some geometric proof, some statistics, and some functions, all reinforcing each other.

It's the standard approach in most of the world, including the IB curriculum, and it's used in a growing share of US high schools. Each course leads to the same place — students finishing Math 3 are prepared for precalculus and calculus, the same as students finishing Algebra 2. The trade-off is that integrated math can feel less tidy (topics come and go) but tends to do a better job of showing how different branches of math connect to each other.

How to Learn Integrated Math

The main practical issue with integrated math at home is finding aligned resources. Most US homeschool curricula and tutoring sites are organized around the traditional sequence, so a parent using IM1-3 may have to piece materials together by topic rather than buying a whole-year curriculum. Common Core-aligned programs are the easiest match.

What tends to work:

  • Pick a curriculum that's actually written as integrated math (Mathematics Vision Project is free and solid, CPM is widely used in schools) rather than trying to retrofit a traditional textbook.
  • Keep a topic tracker. Because content jumps around, it's easy to lose the thread on a strand like geometry between visits.
  • If a kid struggles, drop into traditional-sequence resources by topic — Khan Academy organizes by topic and works fine as a supplement.

Gut-check: ask your kid how this week's geometry topic connects to the algebra they did last month. Integrated math is supposed to make those connections visible. If your kid sees them, the approach is working. If everything still feels disconnected, the curriculum may not be doing its job.
