How I Use It
The Live Problems allow students to have an authentic audience for their solutions. They can submit their solutions online and check back later for published solutions.
We also use various NRICH games and interactives to support problem solving in the math class.
NRICH will get you thinking about math in new ways. The website is a rich source of clever games, activities, and inquiry problems. Some games are playable online, others are mention for offline practice.
My students enjoyed some of the online games, but most of them required mini-lessons from teachers in order to understand how to play. Certain NRICH activities kept my students interested in math patterns and problem solving for extended periods of time. NRICH also has "Live Problems" which are inquiry-based math problems. Students can submit their answers online.
Unfortunately, the website is not very well organized or searchable. It is difficult to tell what games could be played online vs offline. Many of the games involve gather resources, so be sure to plan ahead.
Since NRICH is based in England, the information is not searchable by Common Core standards. It takes some serious time and exploration to pull out activities and problems that will serve your students well. The website is also text-rich which might make it less accessible to some students.
