Students tackle the problem of how to divide a triangular piece of land fairly among four people. They decide whether their method of fair division always works or if it only works in special cases.

Learners discuss Sol LeWitt and conceptual art, then analyze the differences in expressing a concept through model-based inquiry and aesthetic art criticism. They develop a geometric, scientific, or mathematical concept, then create an...

Students are introduced to the concept of convergent infinite series using a recursive geometric construction. They explore the concept of a convergent infinite series using partial sums. Students use formal calculations, visualizations,...

Students explore patterns.  In this patterns geometry lesson, students identify and extend patterns including body parts, movement, geometric shapes, noises, and footprints.  Students create and share an original pattern.

Without ever using the actual term, this exercise has the learner develop the key properties of the midsegment of a triangle. This task leads the class to discover a proof of similar triangles using the properties of parallel...

Fourth graders develop strategies for identifying geometric and number patterns. In this mathematical patterns lesson, 4th graders use pattern blocks to make repeating patterns with numbers and shapes. Students then explore number...

Students create lines and shapes with a compass and a straight edge. In this geometry instructional activity, students investigate square roots, irrational numbers and spirals. They explore nature to see the shapes representing...

First graders listen to Shapes and The Greedy Triangle to identify and describe examples of geometric shapes.  In this geometric shapes lesson, look for geometric shapes in real world places.  Students make a mobile of shapes...

Students explore the relationship between geometry and ancient American art. They see how to recognize geometric properties in specific works and explain how these properties contribute to their meaning and artistic merit.

Students draw a model of the bunny problem which generates the Fibonacci Sequence, spirals generated from golden rectangles and golden triangles; identify the golden ratio in the human body, and find the Fibonacci numbers in nature.

Third graders experiment with, identify, and follow teacher-directed instruction toward understanding two-dimensional geometric shapes found within the environment. Groups of students utilize geoboards to help them explain geometric shapes.

Fifth graders review the concept of a line of symmetry by using pieces of paper that have pictures such as, letters of the alphabet, polygons, and designs made from polygons in order to determine if they have symmetry. The fine,...

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this instructional activity. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is...

Explore the concept of the equals symbol. In this mathematical symbols instructional activity, learners discover the meaning of the equals sign (symbol). They also construct addition and subtraction sentences to understand the concept of...

Students create cubist drawings using grids and enlargement.

Second graders use a number line to understand multiples.  In this number line instructional activity, 2nd graders use a floor size number line and calculate problems with multiples. Students complete a worksheet with multiples.

First graders practice identifying number patterns. For this basic patterns lesson, 1st graders use a large number line and jump to certain numbers to create, identify or extend a pattern. This lesson includes a script to guide the teacher.

Pupils explore the architecture of Frank Lloyd Wright through literature and analyze photographs. For this photography analysis lesson, students read aloud Frank Lloyd Wright and answer questions for the text. Pupils visit a website and...
