Students examine mathematical symbols and formulas included in works of art. They analyze quilts for shapes and they each make their own quilt from squares using geometric shapes.

Students learn the vocabulary of contemporary sculpture and distinguish between abstract and realistic sculpture, mobile and stabile, biomorphic and geometric. They write equations using Calder's mobiles

Students study the history of hard edge painting and discover demonstration techniques using a variety of fonts and discuss lettering. They present a number of abstract works of art with hard edge technique and works of art with text.

Students recognize and name two-dimensional and three-dimensional geometric figures. One group of students will extend the study of polygons to quadrilaterals while another group of students will extend the study of polygons to...

Students create "Mondrian style" paintings in this 4th through 12th grade Art lesson. Emphasis is placed upon learning the styles and art techniques of Piet Mondrian and abstract art. The lesson includes a link to an interactive art...

Students identify patterns found in nature. In this algebra lesson plan, students model situation in nature using fractals. They investigate biological geometric structures and draw conclusion based on geometric concepts.

Students explore kitchen math and following multi-step directions by making pancakes. They assemble the ingredients and make the batter. Students create faces, geometric figures, shapes or lines using pancake batter.

Students investigate geometric shapes through volume and dimensions. In this geometry lesson, students measure, weigh, and calculate sizes and volume based on estimation and calculation. They review important vocabulary related to prisms...

Students create paper bridges. In this geometry and architecture lesson, groups use legal paper and paper clips to design a bridge that will hold 100 pennies. Links to mini-lessons exploring stability of different geometric figures and...

Geometry gets an engineering treatment in an exercise involving a belt wrapped around two wheels of different dimensions. Along with the wheels, this belt problem connects concepts of right triangles, tangent lines, arc length, and...

Students are asked to visualize three-dimensional figures and apply this visualization to problem solving.

Students practice making and interpreting pie graphs so they are better able to decide if a pie chart is the appropriate form of display. Students examine included overheads of different pie charts, and directions on how to make pie...

High schoolers discuss and identify polygons and lines. In this geometry lesson, learners review liner, square and cubic units so they can incorporate it into the lesson on measurement and creating packing that are cost effective.

How much can you tell about a circle from its equation? This detailed lesson plan focuses on connecting equations and graphs of circles. Learners use equations to identify x- and y-intercepts, centers, and radii of circles. They also...

Just about every public building that your students are familiar with has an access ramp which complies with ADA requirements. As it turns out, designing such a ramp is an excellent activity to incorporate slope, the Pythagorean Theorem,...

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Young geometers investigate and apply properties of quadrilaterals.  After a review and discussion of key terms, students use a computer applet to explore four-sided figures and classify them according to their attributes. The...

Hands-on investigation of Riemann sums becomes possible without intensive arithmetic gymnastics with this interactive lesson plan. Learners manipulate online graphing tools to develop and test theories about right, left, and...

Shapes are so fun! Little ones explore, identify, and create shapes using tangrams or pattern blocks. The activity is intended to stimulate critical thinking while engaging learners through play and shape identification. Each child will...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

Round and round we go. Learners first complete a task on writing equations of circles. They then take part in a collaborative activity categorizing a set of equations for circles based on the radius and center.

Take flight with a fun activity focused on graphing data on a coordinate plane. As learners study the data for Granny's hot-air balloon trip, including the time of day and the distance of the balloon from the ground, they practice...

Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...

The class braids irrational numbers, Pythagoras, and perimeter together. The mini-assessment requires scholars to use irrational numbers and the Pythagorean Theorem to find perimeters of rugs. The rugs are rectangular, triangular,...
