Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson, learners calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes. This...

Students explore two-dimensional and solid shapes. In this shapes and patterns geometry activity, students work with a partner to create identifiable objects using tangrams. Students describe the attributes of their shape and their...

Young scholars identify nonstandard units of measurement and investigate area of objects. In this geometry lesson plan, students trace their hands and glue cereal pieces to the print to find the area.

Young scholars create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.

Fifth graders discover congruent figures by investigating graphs and manipulatives.  In this geometry instructional activity, 5th graders identify congruent figures and patterns with their classmates.  Students collaborate in...

Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This lesson gives students a meaningful way to practice these...

Bring out the inner artist with this Abraham Lincoln lesson. Elementary students work on a home project creating a hat similar to Abraham Lincoln's hat. They will use geometry and measurement to create the scale of the hat, then...

An outstanding instructional activity on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about...

Students investigate ways to enhance an object's flying ability.  In this model construction instructional activity, students construct two paper airplanes, one of which is twice as big as the first.  Students compare and...

Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

Students watch videos and fill out worksheets about the turtles and their journey to the Costa Rican beach. In this turtles lesson plan, students learn and discuss survival, predator and prey, and stages of development.

Learners construct a bridge that can hold 100 pennies. For this math lesson, students evaluate the strength of their bridges. They predict how much weight a bridge can hold based on its design.
