Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry instructional activity, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

In this van Allen Radiation Belts worksheet, students are given the formula for the field line of the Earth's inner magnetic field. Students use this equation to find the polar coordinates of a field line in the van Allen Belts. They...

Students investigate octagons using words and shapes. For this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.

Seventh graders become familiar with the history and times which influenced a featured mathematician each month. Through Internet research, they gather information about a different mathematician each month. Students solve mathematical...

In this planet Eris learning exercise, students read about the discovery of this dwarf planet and its characteristics. Students answer 3 questions about the planets, the classification of planets and the definition of planets. Students...

Students construct and compare the actions of various pendulums. In this pendulum motion activity, students build and test different types of pendulums. They conduct experiments with the length of the swing arm and apply mathematical...

Students identify basic geometric shapes. In this geometry lesson plan, students read the book Shapetown and identify the various shapes from the story. Students are given a sheet and draw part of a town using only shapes.

In this algebra worksheet, 11th graders solve quadratic functions using the quadratic formula. They identify the negative roots using complex roots. There is an answer key with this problem.

Tenth graders explore and define the radius and diameter of a circle. In this geometry lesson, 10th graders calculate the circumference and area of a circle using real world objects and shapes. They discuss chords and lines tangent...

Learners examine images and preimages of a mapping and identify isometry. They view images by M.C. Escher, observe teacher demonstrations, and create a translation image, a rotation image, and a dilation.

There are five shapes for scholars to identify: rectangle, circle, square, trapezoid, and triangle. Although there isn't much here, consider projecting this as an all-class warm up. Ask kids to verbalize attributes of each...

Second graders explore triangles and quadrilaterals. They rotate to various centers in the room to identify and examine triangles and quadrilaterals. After presenting a picture to the class, 2nd graders locate right angles, triangles...

Second graders explore the features of triangles and quadrilaterals. In this instructional activity on triangles and quadrilaterals, 2nd graders rotate with their group to five different activities all exploring a different aspect of...

Students create a scrapbook. In this geometry lesson, students use digital cameras to take pictures of geometrical concepts. Students use the pictures to create a "Geotown" scrapbook.

Sstudents explore and analyze the properties of geometric areas.  For this geometry lesson, sstudents use technology to simulate spinners and dartboards in order to fing areas of circles and sectors of circles and compare and...

Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Third graders describe and compare attributes of two-dimensional shapes. They explain geometric terms, angles and shapes. Students demonstrate each vocabulary word with their body and they mirror the body positions associated with each...

Second graders identify different polygons and their attributes. In this geometry instructional activity, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and...

Students investigate the rigid motions of reflection, rotation, translation, and dilation. This investigation be accomplished through classroom instruction and exploration using Geometer's Sketchpad.

Students explore the concept of fractals. In this fractals instructional activity, students discuss Sierpinski's Triangle using an applet. Students discuss the patterns involved with fractals. Students discuss the area of Sierpinski's...

In this polygons worksheet, 4th graders identify and name the 4 polygons drawn on the bottom of the worksheet and then draw a triangle, hexagon and a quadrilateral.

Students explore the concept of perimeter. In this perimeter lesson, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.

Students investigate the concepts relating to creating a tessellation. They include using pattern blocks in order to create interconnecting patterns. Students review translations, rotations, and reflections.

High schoolers create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.
