Students solve geometry problems. In this area and perimeter lesson, students use formulas to solve problems from the textbook. 

Students familiarize themselves with the construct and measure menus. They demonstrate how to use the Sketchpad Calculator. They draw a triangle and construct the centroid. They shade in each of the small triangles and measure the area.

Students explore the relationships between similar figures. In this relationships between similar figures instructional activity, students discuss relationships between perimeter, circumference, area, surface area, and volume of similar...

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

In this online math learning exercise, students determine the length and width of given rectangles given their area. This excellent resource allows the students to check their answers, and to get "hints" should they run into...

In the process of constructing their own "rulers" Students develop a sense of the size of a centimeter and meter. Students select the appropriate "ruler" for the tasks. Finally, 3rd graders calculate the perimeter of objects using...

Students study relationships between angles, side lengths, perimeters, areas and volumes of similar objects. In this lesson students also create and critique inductive and deductive arguments concerning congruency, similarity and the...

The roots metro/meter and therm are the focus of a vocabulary building presentation that includes concise definitions, color-coded examples, and opportunities for guided and independent practice. Part of a series of roots and affixes...

Playing with matches (unlit, of course) becomes an engaging learning experience in this fun instructional unit. Teach pupils how to apply properties of exponential functions to solve problems. They differentiate between quadratic and...

Students investigate the concept of perimeter. They design there own figure and measure the perimeter of it. The lesson plan is given the context of the shape being a path that is traveled by a ladybug. This provides the shape of the...

In this Pick's Theorem learning exercise, students solve and graph 6 different problems that include using Pick's Theorem to solve. First, they use Pick's Theorem to determine the area of the shapes given as well as their own shapes...

Eighth graders measure in feet and inches and convert to explore the relationship between the converted measurements. In this measurement lesson, 8th graders use the whisker and box plot to represent the measurement of a cat. ...

Students explore the concept of area under a curve. In this area under a curve lesson, students find the area under a curve using the Monte Carlo method using random points and probability. Students calculate the area under the same...

Students define and identify transformation and rotation. In this geometry lesson, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.
