Learners begin the instructional activity by identifying what a polygon is and hypothesizing how many struts (diagonals) it would take to make a polygon rigid. They watch a "Magic School Bus" episode then experiment with various shapes...

Young learners view different shapes drawn by the teacher on the board. The teacher identifies each shape by name and discusses the importance of knowing the difference between shapes when building something. The pupils complete the...

Students solve a story problem about how many trees can be planted in a given area. Using a map, they gather information about the size of the area and the dimensions of an acre. They use a specific equation to determine the area of...

In this secondary mathematics lesson, learners investigate the uses and capabilities of a TI-89 application designed for mechanical engineering students. The app contains over 700 pieces of reference information and organized into...

Learners review three types of polygons that are triangles, squares, and hexagons. They use a computer program to draw various types of tessellations. The students use the drawing of a honeybee as inspiration.

Explore the world of shapes! After free tangram exploration and pair share time, learners describe various patterns and shapes in both the natural and designed world. They investigate the use of tangrams to create patterns and shapes.

Students use historical aerial photographs and current aerial photographs to compare the change over time to the land. In this land changing lesson plan, students analyze, compare, contrast, and list the land change in their own community.

Students construct a barrel or other curvy container and then estimate and gauge its volume.

Students learn and practice how to find the perimeter of a polygonal shape. Using a ruler, they measure model rooms made of construction paper walls. They learn about other tools, such as a robot, that can help them take measurements....
