Using Illustrative Mathematics Algebra 1? MathBound follows your chapters.

Illustrative Mathematics Algebra 1 (2019 (IM 9-12 Math), CC BY 4.0) has 7 units and 60 lessons. In MathBound’s free Algebra I game, each unit becomes a sky island and each lesson a landing on it, asking that lesson’s kinds of problem. The book’s own numbers are kept, so your students can find their place.

Follows the 2019 edition of Illustrative Mathematics Algebra 1 (CC BY 4.0), whose Unit 2 still holds the inequality lessons that the newer v.360 moved to a unit of their own. For v.360 choose Illustrative Mathematics Algebra 1 (v.360). Not affiliated with or endorsed by Illustrative Mathematics.
