Students explore the basic geometric shapes and geometric shape vocabulary through the use of geoboards and virtual geoboards. They create a variety of shapes with a partner, build ten different rectangles on their geoboards, and discuss patterns identified in the data.
Students create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and vertical sides) on a geoboard.
Students investigate area and perimeter using a geoboard.  In this area and perimeter using a geoboard lesson, students create a geoboard on their Ti-73.  Students make a 26 vertice board and construct triangles on it.  Students find the area and perimeter of their construction.
Sixth graders demonstrate the concept of area using a geoboard. They experiment with the geoboards with rubber bands, and calculate the area of polygons and triangles using construction paper units.
Young mathematicians calculate the area of rectangles and squares. In 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 units.
Tenth graders explore area of polygons. They find the areas of geoboard polygons using the coordinate method. Additionally, learners investigate problem solving using a coordinate approach.
Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber bands and Geoboards. Through this engaging activity, they will begin to understand and identify the simple fraction of one half as they place two triangles together to make one square. To further their understanding of the basic figures within two-dimensional shapes, learners create shapes using Wikki Stixs. To complete the lesson, the class creates three-dimensional figures such as a cube with marshmallows and toothpicks. Included are extension and family connection activities. Please note that modeling and support will be needed for your youngsters to independently create shapes using hands-on materials as indicated in the lesson.
Jump into equivalent fractions using these fun scenarios for mathematicians to solve. First, they use geoboards to find different ways to divide a rectangle in half. Then, an alien from the planet Fractional is after one half of their candy, but scholars trick him into taking a smaller amount using equivalent fractions. There are two more cooperative games here as well as extensions and all the materials you will need.
Students develop a sense of length on the geoboard, associate attributes of line segments with appropriate terminology (e.g., horizontal, parallel, intersecting, perpendicular, congruent) and develop a working knowledge of order attributes.
First graders create two-dimensional shapes. In this shapes lesson, 1st graders learn about different two-dimensional shapes. Students have many hands-on experiences with these shapes including the use of geoboards, shaving cream, yarn, and drawing shapes. This lesson also includes an opportunity for assessment of a student's ability to follow directions.
Tenth graders investigate geometry using the geoboards. In this geometry instructional activity, 10th graders analyze length using parallel, perpendicular and congruent lines. They discus inequalities and explore different geometric shapes.
Students explore geometric shapes. For this geometry lesson, students use geoboards to construct various geometric shapes. Students identify quadrilaterals and parallel lines.
Fifth graders explore geometric shapes. For this math lesson, 5th graders investigate the characteristics of geometric shapes. Students construct various shapes using geoboards. Students work in groups to develop a PowerPoint slide about a geometric shape.
Third, fourth, and fifth graders explore area measurement. First, they define and identify parallelograms. They then construct parallelograms on a geoboard and determine the area by covering it with paper square centimeters. They also solve story problems about area using the geoboard.
Middle schoolers find the areas of parallelograms, trapezoids, and triangles.  They use a geoboard on the Ti-73 to construct each shape and find its' area. Pupils record the lengths of the figures in tables on their paper.
Middle schoolers find the area of non-right triangles. They will find the area of non-right triangles by changing them into right triangles. They use a geoboard program on their calculators to manipulate non-right triangles. Then they record the length and height of the triangle to ensure the area does not change.
Learners analyze word problems requiring multiplying fractions. They manipulate geoboards as a visual representation, one child completes a multiplication problem, while the other draws an image to collaborate and problem solve in partners. Resources are provided.
Explore the concept of area of shapes. Learners will find the area of triangles, squares, and rectangles using a geoboard application on the graphing calculator. They will also find the area of trapezoids and other irregular shapes by dividing the trapezoids into two or more triangles.
Students review geometry unit content through a vocabulary/word game. They demonstrate understanding using geoboards to answer questions. They work in groups and it's a race to the correct answer.
Fifth graders investigate the Internet to examine the characteristics of quadrilaterals. They create different quadrilateral while learning how to classify them using geoboards and the Internet. They take an online quiz.
