Try Tessellation
Most middle schoolers probably feel that quilting is at best an activity left to their grandmothers. This lesson uses the Zome modeling system to get them to realize how shapes in quilting are really tessellations and repeating patterns....

ExplorA-Pond:3rd Grade Shapes & Fractions
Learners, using a map, drawing or aerial view of a pond, represent the shape of the pond using simple geometric shapes or fractions of those shapes. They identify the numerator and denominator in each fraction created.
Exploratorium
The Four-Square Quilt
Youngsters recognize that triangles can be combined together to make various shapes. The learning activity provides a series of seven steps that engage children in applying transformations to triangles. Pupils use a quilt template and...

How Alike Are We?
Fourth graders find the range, mode, median, and mean for each of the data sets (height and shoe size). They discuss which measure of central tendency for each data set best represents the class and why. Students graph the shoe size and...

Cuisenaire Mats
First graders use Cuisenaire rods to study the mathematical symbols =, <, > for the relationships is equal to, is less than, and is greater than. They use the rods to show visual explanations of common number combinations.
Curated OER
Searching for Angles and Lines
Young scholars work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.
Curated OER
Talking About Your Name in Math Terms
Add imagination and creativity to your math lesson. Young mathematicians investigate ways to express their names in mathematical terms. For instance, they can count the number of letters, analyze the geometric shapes of the letters, or...
