Ryan Andrew Nivens, Tara Carver Peters, and Jesse Nivens
Two ways of drawing cubes on dot paper connect students to life outside their classroom.

Views of Isometric Geometry: Appendix of additional figures

A Cultural Introduction to Math
Alison L. Gear
Kindergarten students, parents, and grandparents explore mathematics from an Aboriginal perspective.
Second Look:
Ethnomathematics: Connecting Mathematics and Culture

How Wedge You Teach the Unit-Angle Concept?
Gayle M. Millsaps
Fifth graders rethink what calculating angle means.

Reflecting on PEMDAS
Kyungsoon Jeon
Forgo rule-driven instruction. Use these helpful tips to teach the order of operations.

Common Core State Standards for Mathematics: The Big Picture
Linda Dacey and Drew Polly
Examine the structure of CCSSM and consider major ideas that will influence their implementation.

Second Look - Ethnomathematics: Connecting Mathematics and Culture

Multicultural Literature as a Context for Problem Solving: Children and Parents Learning Together
Through the literature of different cultures, teachers facilitate family members working together to solve mathematical problems embedded in or related to the text of the stories.

Freedom Quilts: Mathematics on the Underground Railroad
Examine the geometric properties involved in making different quilt patterns and the cultural significance these quilts hold for Africans on southern plantations escaping to freedom. Lesson ideas with mathematical and multicultural connections are provided for classroom teachers.

Honoring Traditions: Making Connections with Mathematics through Culture
Using a non-standardized system of measurement in the Yup'ik culture of Alaska, the article explains how this traditional system can help create connections between mathematical concepts and how these concepts are used in the world outside the classroom.

Illuminations Lesson: Sticks and Stones
Students will play Sticks and Stones, a game based on the Apache game "Throw Sticks," which was played at multi-nation celebrations. Students will collect data, investigate the likelihood of various moves, and use basic ideas of expected value to determine the average number of turns needed to win a game.

Connections Standard - Pre-K through Grade 12
When students can connect mathematical ideas, their understanding is deeper and more lasting. They can see mathematical connections in the rich interplay among mathematical topics, in contexts that relate mathematics to other subjects, and in their own interests and experience. Through instruction that emphasizes the interrelatedness of mathematical ideas, students not only learn mathematics, they also learn about the utility of mathematics.
