Fourth graders develop strategies for identifying geometric and number patterns. For this mathematical patterns lesson, 4th graders use pattern blocks to make repeating patterns with numbers and shapes. Students then explore number...

Tenth graders investigate the geometric concept of quadrilaterals. They are given a set of shapes and asked to sort the quadrilaterals from the others. Then working in pairs they discuss the characteristics and write down the description...

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...

A geometry game that resembles Battleship is the foundation for hide and seek where "hiders" draw shapes on coordinate planes and "seekers" must guess the shape and its location based on questions and clues. Reproducible, paper-sized...

Third graders use fractions to describe part of a set. For this fractions lesson, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This lesson includes a scripted...

Student identify the solution using geometric mean. In this geometry lesson, students create right triangles where the altitude of the triangle is the side containing the right angle. They modify shapes using Cabri software and observe...

Student sinvestigate the area and perimeter of polygons. They differentiate between similar and congruent polygons.. They identify the ratio and proportions of the sides and angles of polygons.

Students define trapezoids and their shapes. In this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.

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 make conjectures of intersecting circles. In this geometry lesson, students observe circles and their position in space. They investigate and observe two and three dimensional objects.

Students calculate the distance from the vertex of a triangle to the center. In this geometry lesson, students find the shortest distance between a point and the vertex of a triangle. They relate this concept of distance to the real world.

Students perform operation with secant and tangent lines. In this calculus activity, students find the derivative and relate it to the slope of a line. They differentiate between secant and tangent as they intersect a circle, using Cabri.

Students define keywords that are important to solve problems. In this geometry instructional activity, students find the arc length and angle of a circle. They convert between radians and degrees.

Students will read the short story "Meenakshi's Magic Hands" by Santhini Govindan and view a slide show of photo images interspersed with the text to learn of the art form of Kolam. Students read and reflect upon a nonfiction essay,...

Students problem solve to open a cube to create different shapes. In this problem solving lesson plan, students are given a cube and the shapes to open it up to, and they have to cut the cube open to make certain shapes. This gives them...
