In celebrating the Journal's 20 years of publication, one of its many storylines in science education is identified, and a potential second storyline in mathematics education is introduced. The first looks back 20 years to trace a trajectory of articles about enhancing school science with Indigenous ways of living in Mother Earth. The second looks ahead to what may likely evolve into a trajectory about enhancing school mathematics with Indigenous mathematizing. The article ends by describing a recent research study that gives detailed texture to this emerging trajectory.
