Using Holt McDougal Larson Algebra 1? MathBound follows your chapters.

Holt McDougal Larson Algebra 1 (©2012 Common Core edition) has 11 chapters and 79 lessons. In MathBound’s free Algebra I game, each chapter 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 2012 Common Core printing (11 chapters, 75 sections), not the 13-chapter 2007/2011 book.
