In this geometric figures worksheet, 10th graders solve and complete 11 different word problems. First, they find the area of a regular octagon with a given side. Then, students find the area of each shaded region. They also find the...

Students start with $19 of Cookie Mining Money with which they must buy his/her own "mining property" or cookie. After cookies are bought, students give their "mine" a name, record it, along with the price of their cookie on the sheet.

Third graders utilize different types of computer programs, such as Microsoft paint and Microsoft Word to study and create different types of polygons. They use PowerPoint to create a story about a shape and others that it meets during a...

Sixth graders identify benchmark angles as they are embedded into a circle grid. They observe the teacher using an angle ruler and complete a Star Spangled worksheet, play the game Tomb Robbers, and as a class discuss their game winning...

Students read A Tree is Nice and It Could Still Be a Tree. In this tree planting lesson, students compare and contrast private property and common resources. Students identify the needs of a tree and follow the directions to plan a tree...

Fourth graders design a classification system to categorize animate and inanimate objects. They discuss the advantages of grouping things as they classify buttons, leaves, shells.

Students examine the principles of electrophoresis. They evaluate both the agarose and polyacrylamide system of molecular separation. In order to bring the concepts of genetics and evolution full circle from DNA to protein, students...

Fourth graders use candy to make a comet. In this lesson, 4th graders examine the role comets have played throughout history, students watch NASA videos about comets and complete the lesson by making an edible model of a comet. This...

Students investigate the natural characteristics of animals by completing a coloring activity.  For this animal properties lesson, students investigate the reasons different animals have specific colors, and how it is essential for...

Second graders listen to a book read to them entitled, WHAT MAKES A RAINBOW and recall and describe their five senses and what parts of their bodies use their five senses and then complete the Catch a Rainbow activity sheet using a...

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

In this geometric calculations of solar storms activity, students use a diagram indicating the location of 2 STEREO satellites, the earth and the sun to calculate the distance between a Coronal Mass Ejection and the Earth. They use...

Students create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Students solve quadratic equations and identify functions. In this algebra lesson, students graph parabolas and identify properties describing the shape of the parabola. They find the vertex and rewrite the equation in standard form.

Learners slice cones and identify the different conics formed. They then derive the formula to solve problems involving cones. Pull out the TI calculators to visualize the slicing and the different parts and properties created.

In this binary operations worksheet, 7th graders solve and complete 12 different problems that include various types of binary operations. First, they determine if the operation used is commutative. Then, students name the identity...

Students explore the concept of vertex-edge graphs.  For this vertex-edge graphs lesson, students try to construct a graph with a given diameter, number of vertices, size, and planarity.  Students construct various vertex-edge...

After reading a statement, learners decide if it is a fact or opinion. Then, they write a sentence explaining how they know their answer is correct. The sheet contains 25 fact and opinion sentences.

Students calculate the measurements of the inscribed angles of a triangle. In this geometry lesson plan, students relate the hypotenuse of a right triangle and the diameter of a circle to each other. They calculate the diameter of a...

Students differentiate between inscribed quadrilaterals and parallelograms. In this geometry instructional activity, students identify the shaped of the polygons when it is inscribed inside of a circle. They calculate the missing angles...

Students use the secant and secant segment theorem to solve problems. In this calculus lesson, students identify where the secant line crosses on a circle. They create circles and secants using cabri software.

Students calculate the inscribed angle of a triangle. In this geometry lesson, students identify the angle created by intersection of a triangle and a circle. They see the relationship between the arc and the angle.

First graders practice manipulating shapes into different locations. They see that even though shapes may look different when they are moved into different locations, the shape remains the same with the same properties. They make...
