## About Us

This virtual filing cabinet is a collection of engaging activities and resources aligned to the Nova Scotia mathematics curriculum. It is curated by Erick Lee, a Mathematics Support Consultant from the Halifax Regional Centre for Education.

The site was inspired by the WNCP Orchestrated Experiences for High School Math site which is another great collection of activities aligned to the WNCP curriculum.

## Additional Problem Resources

**Problem-Based Lesson Search Engine from Robert Kaplinsky -**Awesomesauce.

**Teacher Created Desmos Bank**- A collection of teacher generated Desmos activities.

**3 Act Math Tasks from Tap Into Teen Minds**- A collection of 3 Act Math Tasks from a number of different authors in an easy to search web site.

**Math Mistakes**- This site is about compiling, analyzing and discussing the mathematical errors that students make. The site is edited by Michael Pershan, a middle school and high school math teacher from NYC.

**Illustrative Mathematics**- Providing instructional and assessment tasks, lesson plans, and other resources for teachers, assessment writers, and curriculum developers.

**Open Middle - Challenging Math Problems Worth Solving**- Open Middle problems have a “closed beginning” meaning that they all start with the same initial problem; have a “closed end” meaning that they all end with the same answer; and they have an “open middle” meaning that there are multiple ways to approach and ultimately solve the problem.

**Mathematics Assessment Project (MAP)**- The Mathematics Assessment Program (MAP) aims to bring to life the Common Core State Standards (CCSSM) in a way that will help teachers and their students turn their aspirations for achieving them into classroom realities. MAP is a collaboration between the University of California, Berkeley and the Shell Center team at the University of Nottingham, with support from the Bill & Melinda Gates Foundation. The team works with the Silicon Valley Mathematics Initiative and school systems across the US and UK to develop improved assessment. The materials from this project will exemplify CCSSM in explicit down-to-earth performance terms.

**Which One Doesn't Belong?**- a website dedicated to provided thought-provoking puzzles for math teachers and students alike. There are no answers provided as there are many different, correct ways of choosing which one doesn't belong.

**Estimation 180**- A daily number sense estimation photo activity. Also follow @Estimation180 on Twitter.

**Would You Rather?**- Asking students to choose their own path and justify it. A great collection of questions focused on mathematical communiction and reasoning.

**Math Arguments 180**- 180 Days of Ideas for Discussion in Math Class.
