High schoolers identify the properties of a sphere. In this geometry lesson, students calculate the surface area of spheres using the formula derived by nets. They identify the radius and diameter of the sphere.

Tenth graders investigate the volume of a cylinder.  In this geometry lesson, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions.  The lesson progresses to the use of the formula to find...

Students practice representing problems found in the real world in terms that can be translated into mathematical expressions. The situations are represented in tables and graphs by students.

Learners review types of polygons and list several examples of each. They assume the role of a landscape artist interviewing for a job. They create sketches of their plans for six polygonal gardens and write an expository paragraph...

Students develop an appreciation for complex structures in nature. They observe patterns in nature in relationship to the Real World. Students use observation skills to assist in problem solving. They show comprehension of the concepts...

Students use numbers as descriptors. In this mathematical inquiry lesson, students use numbers to describe, classify, and compare plants. Students are made aware that numbers can be used to describe things in the world around them.

Students investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Students locate the prefix "tri" in a variety of words and make connections with...

Students design different shaped plots and determine the perimeter, area and shape of each. They compare the shapes that have the same area but may have different perimeters.

Fourth graders investigate ecosystems. In this ecosystem instructional activity, 4th graders explore producers, consumers, and decomposers and study the interdependence of each.

Students, after reading the explanation given below, use FoilSim to determine the weight of the aircraft that can be lifted by a pair of wings of each type. They also design a unique platform of a wing to lift a plane weighing 11500 pounds.

Students model the geometric relationship with graphing. In this geometry lesson, students differentiate between parallel, perpendicular, similar and congruent shapes. They use properties of polygons to differentiate their shapes...

Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...

Students study pyramids. In this prisms lesson plan, students explore the attributes of pyramids. Students will explore the lateral surface area of pyramids and be able to distinguish pyramids from other space shapes.

Students classify prisms according to their attributes. In this classifying prisms lesson, students explore different prisms. Students generate observations of the attributes and classify the prism correctly.

In this effect of transformations on coordinates worksheet, students determine the coordinates of 4 geometric shapes on a grid after a given transformation.

In this math worksheet, students create a model for the geometric shape of the cube. Students use this math net to cut, fold and tape the figure.

Learners use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings

Second graders, using a minimum of four space figures, create a mobile. They use a "Draw" program to first plan out their figure.

In this rounding money activity, students identify the money amounts in each examples and round to the nearest dollar for the 10 examples.

Second graders use a checklist to construct a Geo-Town map including a compass rose, a map key, and a paragraph about a walk around Geo-Town, using appropriate geometric and directional vocabulary to identify the two-dimensional figures...

Students explore the concept of fractal patterns. In this fractal pattern instructional activity, students use an applet about the Hilbert Curve to answer questions about rectangles and other polygons. Students derive the fractal pattern...

Pupils build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using logs.

Middle schoolers build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...
