Examine the relationship between time and geometry. A series of five lessons provides a grade-appropriate problem from elementary through high school. Each problem asks learners to compare the movement of the hands on a clock to an angle...

Young mathematicians calculate the area of rectangles and squares. For this geometry lesson, learners are grouped in pairs and use geoboards to construct rectangles. They calculate the area of the figure by counting the number of square...

Students research flag designs and their geometric configurations. They design their own fraction flag and utilize the concepts of measurement, geometry and fractions to their designs. Each student attaches a craft stick or short dowel...

Students study quilts. In this history/geometry quilt activity, students discover the history behind quilt making and get a chance to make quilt blocks of their own. They work independently to make a quilt block out of construction paper...

The Common Core is intended to help all children meet high academic standards. Here is a Common Core designed lesson that is intended for learners with communication or language difficulties. The lesson is written in a narrative style...

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging learners to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Students investigate cubes. In this geometric solids lesson, students review geometric concepts previously taught, then logon to a computer game in which they find cube figures and identify the shadow of hidden cubes.

Young artists divide a piece of graph paper into sections using rectangles, squares, and triangles. They then fill each section with patterns of shape and color. Elementary graders describe how their patterns are organized. Secondary...

Students make three dimensional shapes with nets. In this nets activity, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use...

Students explore perimeter. In this geometry and measurement lesson plan, students create squares and rectangles using given perimeters. Students construct four sided shapes with given perimeters using the computer program "Math Keys:...

Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson...

Explore the concept of creating and describing 2D and 3D shapes.  Using geometry your scholars will describe the attributes of shapes and their properties.  They explore and discover what happens when you combine shapes and...

Third graders engage in an enrichment lesson exploring the concepts of area and perimeter. They construct new pentominoes that are 3 times the size of normal ones and then identify the area and perimeter measurements. They then create a...

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

Students measure their body. In this measurement lesson plan, students use a string to measure their height and the circumference of their head. They record this information on the worksheet provided and answer questions as a group. 

Students explore intersecting lines. In this intersecting lines lesson, students investigate shapes consisting of parallel, perpendicular, and similar lines. Students investigate these lines in shapes around them.

Students examine transformations. In this math lesson plan, students view and describe flips, slides, and turns. Students practice making transformations with shapes.

Students explore circumference and diameter. In this math lesson, students apply their knowledge of circumference and diameter to solve mathematical riddles. Students apply this knowledge to find circumference and diameter of various...

Students create tessellations. In this math instructional activity, students explore symmetry and patterns through the creation of a tessellation. Students design and create their own tessellation.

Shape shifters recognize characteristics of polygons. Embracing language arts skills in addition to math, they use a thesaurus to pinpoint specific attributes of a set of polygons. They also participate in a 21-question guessing game...

Students find coordinate points on a grid and create a line graph with those points. This lesson should ideally be used during a unit on various types of graphs. They make and use coordinate systems to specify locations and to describe...

Students identify lines in everyday images.  In this art analysis instructional activity, students practice drawing diagonal, vertical and horizontal lines on pieces of chart paper.  Students examine a page from a magazine and...

Third graders observe angles in their classroom and create an angle finder to represent them.In this angles lesson, 3rd graders classify angles as acute, obtuse, right or straight. Students find the differences and similarities in angles.
