Teachthought describes this as "While the site is simple a crudely interactive graphic with links to videos, it has, in one fell swoop, creatively curated some of the most compelling and engaging "problems" in mathematics. From Benford's Law to French Numbers, to whether or not zero is an even number, it frames the content area of math-which is often riddled with rote practice of very traditional arithmetic and formulas-in a problem-based learning kind of approach.
Fantastic resource for bell ringers, test questions, math project-based learning ideas, or as a model for students to curate their own curiosities about the incredible-and poorly marketed-world of mathematics."
This site provides an extensive collection of free resources, math games, and handson
math activities aligned with the Common Core State Standards for Mathematics.
Our math printables are suitable for use in math centers, small group or whole class
settings. Instructions for each activity are presented in large print on a task card in
child-friendly language to enable students to work on tasks independently after a brief
introduction to the task.
All materials and activities on the site are designed to support the Common Core
State Standards and are based on the belief that effective mathematical learning is
best achieved when students are given frequent opportunities to develop their own
problem solving strategies, to pose questions, and to engage in mathematical inquiry
through the use of open-ended tasks.
