Fall into Healthy Shapes
Kindergartners identify geometric shapes by planting a fall garden. They start their seeds in containers that have different shapes, and keep track of their plants based on those shapes. This brilliantly designed and incredibly thorough...

The Same, Similar, and Different
In this same, similar, and different learning exercise, students compare seven shapes and fill in the blanks with like or alike. Students answer eight comparisons.

Comparing 3-D Shapes
How is a sphere like a prism? Learners compare and contrast 3-D shapes, first drawing each in the boxes provided. If this is too advanced, supply pre-cut images of the shapes for students to choose from and glue onto the instructional...

Similar Shapes
In geometry, similar and congruent shapes are often confused. Shapes that are similar are the same shape, but a different size. This activity gives young learners some practice in identifying similar shapes. There are five polygons...

Recognizing 3-Dimensional Shapes
Three-dimensional shapes are all around us; expose young geometers to this concept as they focus on identifying four figures: cube, prism, sphere, and pyramid. Learners begin by matching four objects to the shape each resembles (i.e. a...

Areas of Geometric Shapes with the Same Perimeter
A triangle, square, hexagon, and circle all have a perimeter of one unit. Eighth graders must attempt to find the area of each and arrange them in order from least to greatest areas. A terrific task for applying four different area...

Using the Web to Explore Shapes
Third graders research the Internet to locate geometric designs in familiar buildings. They review shapes, solids, angles and symmetry as they research websites of familiar buildings in Louisville. They record the information they see...

Shapes from Shapes
Geometric shapes are really cool. Examine triangles, quadrilaterals, trapezoids, rhombuses, parallelograms, pentagons, and hexagons with your class. They draw large shapes and small shapes then compare them to understand their shapely...

Representing 3-D Objects in 2-D
How does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.
Bowland
Three of a Kind
One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.
