Tenth graders explore congruent triangles.  In this geometry lesson, 10th graders investigate the conditions necessary to prove two triangles congruent.  The lesson combines dry erase board activities and the use of technology.

In this geometry worksheet, 10th graders solve problems with quadrilaterals. They calculate the sum of the angles, find missing angles and identify properties of quadrilaterals. There are 16 questions with an answer key.

Students measure the perimeter and area of their polygons. In this geometry lesson plan, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of...

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

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.

Third graders construct and use vocabulary flipbooks to draw and describe three-dimensional figures. They utilize worksheets and access websites imbedded in this plan which help them construct their books.

Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

Fifth graders classify triangles. For this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

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

Students watch the Cyberchase episode, "The Poddleville Case" and play online games to examine how patterns are sequences that repeat or change in an orderly way. The lesson culminates with students creating their own patterns to use in...

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...

Students identify and construct figures that tessellate. They investigate which regular polygons tessellate and how to modify them to make other tessellating figures. Students explore how naturally occurring tessellations have been...

Students explore the concept of sine. In this sine lesson, students create a sine graph from tooth picks. Students create a unit circle with tooth pick length radius. Students then take the tooth picks from the unit circle and put them...

Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...

Students classify angles. In this angles activity, students explore the characteristics of angles, triangles, quadrilaterals and circles. They identify polygons and sing a classifying angles song. Students participate in a...

Third graders understand what a line of symmetry is and how to draw symmetrically. In this monster symmetry lesson, 3rd graders create an original monster that is symmetrical. Students participate in additional symmetry activities.

In this secondary mathematics worksheet, students investigate exponential growth as they predict the height of a stack of paper formed by tearing one sheet of paper in half over and over again for thirty tears.  The one page...

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Students design a skydiver and parachute constraption to demonstrate how drag caused by air resistance slows the descent of skydivers as they travel back to Earth. They experience how gravity pulls the skydiver toward the earth and how...

Second graders view examples of active lifestyles in works of Robert Harris, and list and graph their daily activities to see if they lead active lifestyles. Students then name forms of entertainment that require practice,...

Students discuss elements of fairy tales, examine selected piece of Robert Harris' art, and compose fairy tales based on what they see and imagine. Students then view homes in Harris' artwork collection, create home in which they would...

Students become familiar with the style of architecture of medieval times.  In this architecture instructional activity, students design a model of a medieval castle including its cornerstone. Students understand scale in their...

Third graders create a butterfly drawing that includes the elements of art and principles of design. They create artwork that can be made into ceramic tiles to be installed around the classroom doorways in our new addition.
