NCTM is committed to offering standards-based resources that improve the teaching and learning of mathematics for each and every student.
Classroom Resources:
NCTM Illuminations
Illuminations are our one of our most popular PreK-12 resource being used in the classroom each year. Browse our collection of more than 700 lesson plans, interactives, and brain teasers.
Here are some of our most popular interactives, according to our users!
Notice and Wonder
When students become active doers of mathematics, the greatest gains of their mathematical thinking can be realized. NCTM members can engage with PreK-12 resources to support the implementation of the Notice and Wonder strategy on this webpage.
Check out our new library of Notice and Wonder Lesson Plans!
Problems of the Week
This extensive library hosts sets of math problems suitable for students PreK-12. The resources span multiple topics and members have access to the over 1,000 problems and supporting materials!

Math Sightings
These stories and lesson sketches, focused in the middle and high school grades, are meant to help your students extend their view of the world a little bit by using math to make sense of experiences in daily life.
Student Explorations in Mathematics
NCTM members can browse the extensive archive of Students Explorations in Mathematics activities and materials suitable for grades 5-10. Many activities are hands-on and related to popular topics that can be tied in with other units, such as sports, elections, nutrition, and more.
Figure This!
Figure This! demonstrates challenging middle school mathematics and emphasizes the importance of high-quality math education for each and every student. Find interesting math challenges that middle-school students can do at home with their families. These challenges are free to members and non-members!
Activities with Rigor and Coherence
ARCs are Activities with Rigor and Coherence that span grades K-8. Each ARC is a series of lessons that addresses a mathematical topic and demonstrates the vision of Principles to Actions: Ensuring Mathematical Success for All.
Reasoning and Sense Making Task Library
In order for high school students to be engaged in reasoning and sense making in the classroom, the task—what students are asked to do—is critical. While linking the task directly with NCTM’s Focus in High School Mathematics: Reasoning and Sense Making, NCTM’s Principles and Standards for School Mathematics, and the Common Core State Standards, each item addresses task design, teaching design and student engagement.
