Our Dynamic Number Line Tool is Now Available to All!

Team News
Teachers and students can now access our dynamic number line tool for free. The tool is a great way for students to explore fractional reasoning, integer operations, irrationals, the development of the real number system, and more. We suggest students and teachers first work through our set of example assessment items (and share your thoughts through the feedback form at the bottom of the page) before going further with the blank slate version. Let us know what you think!

SUDDS Conducts Design Study with Partners at Highland Middle School

Team News
In November, the SUDDS learning science team worked with teachers and sixth grade students at Highland Middle School in Harnett County, NC to conduct a design study on sixth grade ratio topics. The goal of the study was to better understand how teachers use Math Mapper to guide their instruction and how students use Math Mapper to guide their learning. With a shared curriculum in use across teachers, the differences and commonalities in how teachers and students respond to and use the data could be examined. Thus, Dr. Confrey and her team wrote a curriculum targeting the development of a conceptual understanding of ratio. This ratio curriculum was built upon empirically supported learning trajectories that describe the benchmarks and strategies exhibited by students as their understanding of a concept increases…

Middle Grades Students’ Interpretations Of Addition Of Fractions Using An Interactive Number Line

Presentations
Meetal Shah, our research assistant, presented at the NCSU Graduate Student Research Symposium on March 23. The presentation summarized Meetal’s study that investigated how middle grades students solved problems that involved the addition and subtraction of fractional magnitudes using an interactive number line (NL) and coordinated the context and the features of the digital tool in doing so.
