Young scholars investigate circles and compound locus. In this geometry lesson, students identify the distance from a point to a line. They use Cabri software to create lines and circles.

Students differentiate between ellipse and hyperbola. In this algebra lesson, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Students identify the properties of a dragon curve. For this geometry lesson, students identify sequences and patterns as they solve fractals. They investigate patterns found in nature.

Students identify the secant segment of a circle. In this geometry lesson, students investigate secant lines formed outside the circle. They use Cabri software to create drawings and explore circles and secants.

Students explore secants and circles. In this geometry lesson, students identify the properties of two and three dimensional shapes. They create arguments to prove the theorems are true.

Young scholars identify the properties of chords. In this geometry lesson, students multiply chord segments to find the solution to their problem. They construct two chords that cross on  a circles.

Third graders arrange numbers up to 1,000. In this arranging numbers lesson, 3rd graders play a game to try and build the biggest number they can using number tiles.  Students work in groups to draw number tiles from a jar and...

Students factor trinomials and other quadratic functions. In this algebra lesson, students solve trinomials containing negative and positive coefficients. They factor quadratics of difference squares as well as regular polynomials.

Learners become familiar with the achievements of the artist Faith Ringgold. They take notice of the patterns in their environment. They connect the mathematical concept of patterns to create a class quilt.

Students make observations about shapes and 1-, 2-, and 3-dimensional objects. They conduct observations and make predictions regarding transformations of simple geometric shapes. They identify shapes that occur in household items.

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Ninth graders solve linear equations. In this algebra lesson, 9th graders discuss the steps for solving linear equations and work through examples with the teacher. They work in pairs to create their own linear equation and complete a...

Students are introduced to the notion of surface area and volume, learn the terminology used with surface area and volume and have experimented with the surface area and volume of different prisms.

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

Students construct two dimensional models to illustrate squared numbers. In this geometry instructional activity, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between...

Students explore symmetry.  For this geometry and scientific inquiry lesson, students design paper airplanes with middle line symmetry, as well as right, obtuse, and acute angles.  Students measure the plane's angles using a...

Young scholars perform transformations on their graphs. In this algebra lesson, students identify the pre-image and image. They find and identify congruent shapes and isometry.

Middle schoolers examine and compare traits of humans and crocodiles.  In this crocodile instructional activity students use a ratio to estimate the height of a person and compare that to a crocodile. 

Students transform polygons.  For this tessellating lesson, students design a picture containing a translation and a rotation.  They create a template of a translation or a rotation.  Students tessellate and decorate a...

First graders explore eight geometry activities that improve understanding of positional words and shapes. They identify, describe, and create simple geometric figures. They help another student who may not understand the concept yet.

Students explore the concept of quadrilaterals. In this quadrilateral lesson, students play with a floor tile applet to see that there are many types and characteristics of quadrilaterals including parallelograms, trapezoids, rectangles,...

Students build a model of their school playground. They view models from the classroom (such as a globe, doll house, or cars). Students share observations about the models. They use a paper mat to represent the playground and use...

This lesson introduces students to the ideas involved in understanding fractals. They develop a sense of infinity, self-similarity and recursion and

Students practice calculating probability, see how geometry can help solve probability problems and explore platonic solids.
