Algebra I — read the structure of change.
Patterns, linear and exponential functions, inequalities, and quadratics — the full TEKS Algebra I ladder, drilled to fluency with worked solutions on every rep.
Train at your level.
Pick a module and start solving. Problems are generated fresh every time and graded instantly by our in-browser math engine — type 3/4, 0.75, or sqrt(5) and correct is correct. Two right answers in a row and the ladder climbs; every rep counts toward the climb.
What you'll train
Every module opens with foundations recall (levels 1–2), then ramps to mastery-level challenge (levels 3–5). The gym adapts as you answer.
Module 1 · Searching for Patterns
16 skill generators · 7 foundations skills (levels 1–2) · ladder to level 5
Module 2 · Exploring Constant Change
12 skill generators · 4 foundations skills (levels 1–2) · ladder to level 5
Module 3 · Modeling Linear Equations & Inequalities
12 skill generators · 3 foundations skills (levels 1–2) · ladder to level 5
Module 4 · Investigating Growth & Decay
12 skill generators · 4 foundations skills (levels 1–2) · ladder to level 5
Module 5 · Maximizing & Minimizing
13 skill generators · 5 foundations skills (levels 1–2) · ladder to level 5
The first language of change.
Every subject that models the world — physics, economics, medicine — speaks in linear and exponential structure, and Algebra I is where you learn to read it. Master the ladder here, and every course above it gets lighter. We rise not by accident, but with intention.
