Ratio Design Study: What We Learned

Last November, we conducted a design study with our partners at Highland Middle School, in which teachers used a SUDDS-designed curriculum and our cluster assessments to teach a sixth-grade unit on ratio. We spent a long time afterwards analyzing the data from the study, and have compiled some recommendations for teachers teaching ratio in a blog post.

What’s New in Math-Mapper

  • A robust practice environment. This feature, available to students in our partner schools, offers real-time feedback on specific questions, so students can see their progress along the learning trajectory. Students can choose to practice a specific construct in the map and focus on progress levels where they need the most practice. For information on accessing and using practice, see this document.
  • A curated collection of high-quality curricular materials. Use the Resourcer to find excellent curricular materials, freely available on the web, that are aligned with Math-Mapper’s constructs. The Resourcer includes SUDDS-made materials on ratio and statistics.
  • A dynamic number line tool. Teachers and students can now access our dynamic number line tool for free through our website. 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!

What’s Next in Math-Mapper

  • A dynamic calendar tool. Soon teachers will be able to use the Sequencer to map their existing pacing documents into Math-Mapper. Assessments and curricular materials will be linked to a calendar so teachers can see at a glance what is coming, when.
  • New student and class reports. We are will be making it even easier for students and teachers to gauge student learning and decide on next steps.
