CCSS Math Standard: 3.G.1

Reason with shapes and their attributes. Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

What’s In My Brain: H vs Arrow

Two columns. One is an example, one isn’t. Can you figure out the hidden rule before the big reveal?

Gr 1, 2, 3, 4, 5, 8

What’s In My Brain: Pentagon vs Pentagon

We’re looking at regular vs irregular polygons.

Math Curiosity: The Coloring Problem

No video gets me more email from students! How few colors can you use to color in any map so that no two, neighboring regions are the same color?

Gr 2-8

Grouping Quadrilaterals In A Hierarchy

Can we classify quadrilaterals like we classify living things?

Gr 1-5

Lines, Line Segments, Rays, and Infinity!

A lesson about lines, line segments, and rays that avoids dull memorization. Instead, we ponder this delightful question: Which is longer, a ray or a line? Then, kids consider what these different geometric concepts would think about each other.
