About Number Stories
Number Stories are real-world questions based on real-world contexts supported by factual sources. Both contexts and questions are written for, and by, a wide variety of individual users such as school students at any level, teachers, teacher-educators, home-schoolers, district supervisors, curriculum developers, and others who are simply interested in how mathematics can be used to solve problems or model situations in their lives.
