Eighth graders engage in a lesson that is concerned with examining two dimensional figures with different properties that include circles, triangles, queadrilaterals, etc... They identify the types of figures that is identified as polygons.

Fifth graders listen to "Grandfather Tang's Story" and use tangram pieces to create animals described by the main character.

Students use this problem to develop spatial skills. As the students handle the shapes and join them together they strengthen their understanding of the attributes of shapes. This lesson also gives students the opportunity to make up...

Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...

First graders practice identifying simple geometric shapes. As a class, they discuss positional words and review the words for simple shapes and their characteristics. They work together to create their own puzzle using the shapes.

First graders analyze objects and make a graphing picture to analyze the data. In this graphing lesson, 1st graders complete an object graph assessment, a picture graph assessment, and a bar graph assessment to analyze their given objects.

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

In this math worksheet, students look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

In this geometry worksheet, students practice finding the area of 11 polygons using diagrams which include units in both standard and metric measurement. They solve for the area of 11 polygons using words that describe the polygons that...

In this math terms puzzle learning exercise, students read the description for each math term. Students try to guess what each term is. Students circle the third letter in the box to check their answers.

In this proportions and similar polygons worksheet, students solve the problems that use proportions, rations, fractions, and similar polygons.

Students explore the concept of minerals. In this minerals lesson, students discuss how cooling affects the size of crystals. Students discuss how the structure of minerals is a tetrahedron. Students discuss the structure of silicates...

Third graders use fractions to describe part of a set. In 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...

Students investigate how to make a good parachute. In this physics lesson, students observe the motion of parachutes as it falls and measure the time. They collect data and calculate the average descent time for each canopy shape.

These activities provide an opportunity for students to explore the area formulas for triangles, trapezoids, and parallelograms.
