KAS Math Standard: KY.3.G.1.a

Recognize and classify polygons based on the number of sides and vertices (triangles, quadrilaterals, pentagons and hexagons).

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.

Gr 1-8

Grouping Shapes by Parallel and Perpendicular Sides

Which shapes go together based on parallel and perpendicular lines?

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

Math Curiosity: Magic Triangles

Can you make each side of this triangle add up to 9 using the digits 1-6?

Gr 1, 2, 3, 4, 8

What odd and interesting shapes can your students find in this geometric image?

Gr 1, 2, 3, 4, 5, 7

What’s In My Brain: Trapezoids or Not?

Which are trapezoids and which are not?

Gr 1-8

Intersecting Angles and Streets

There can never be just one angle.

Gr 1, 2, 3, 4, 7, 8

The Angles of a Triangle

Why tell a kid the rules of a triangle when they can discover them!?

Gr 1, 2, 3, 4, 5, 7, 8

Grouping Quadrilaterals In A Hierarchy

Can we classify quadrilaterals like we classify living things?

Gr 1-5

Deducing the Area of Triangles

Using patterns, students try to deduce where that area formula came from.

Gr 1, 2, 3, 4, 6, 7
