Students explore about triangles and their relationship to the worlld around them. They are able to identify triangular shapes in their environment. Students are able to communicate to one another their understanding of triangles outside...

Third graders create art using shapes. In this shapes and patterns instructional activity, 3rd graders explore multiple ways of combining shapes to create new objects and art.

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...

Learners identify names of angles. They use a large clock to demonstrate angles using certain times of day. Given a geoboard, students create figures with acute, right, and obtuse angles.

Learners explore the concept of polygons on a two-dimensional plane. They identify polygons in everyday life and draw different polygons according to their classification. Using a geoboard and geobands, they consrtuct polygons and even...

Pupils identify a number of different shapes and their corners and sides. Using a cut out of the shape, they stand on the appropriate shape on the floor and count the sides and corners. They use a geoboard to construct their own shapes...

Fifth graders will use geoboards to construct parallelograms. They will determine the area of a rectangle and then apply that thinking to determine the area of a parallelogram. Note: The format of this lesson is much like a PowerPoint,...

Students explore perimeter, area and volume. Using geoboards, toothpicks, and marshmallows, students create specific shapes. They are directed to use formulas to find the volume, area, and perimeter of the created shapes. In groups,...

Young scholars scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go...

Pupils practice a variety of strategies with varying numbers of tiles to form shapes and then find the minimum and maximum perimeter for each one. Each group is assigned a different area to build either with square tiles or a geoboard....

Second graders create a shape garden. In this polygons lesson, 2nd graders practice making shapes using a geoboard and read the book The Greedy Triangle by Marilyn Burns.  Students also design a shape garden using construction...

First graders explore two-dimensional shapes. Individually, children follow directions to draw shapes. Learners use shaving cream, geoboards, yarn, marshmallows, and toothpicks to create shapes. As a class, 1st graders brainstorm...

Pupils calculate area using the geoboard application on their calculators. They use a TI-73 calculator to find the areas of the shapes provided in the accompanying worksheet. Screen shots and instructions for creating shapes in the...

Seventh graders recognize the characteristics of isosceles triangles. In this isosceles triangle activity, 7th graders use geoboards to create isosceles triangles. Students record results and explain why they have an isosceles triangle.

Sixth graders find the perimeters of polygons and use perimeters to form polygons. For this perimeter lesson, 6th graders study vocabulary associated with finding perimeter such as polygon, line segment, variable, and formula. They make...

Young scholars investigate the concept of a linear function. They use geoboards to find the interior angle sums. The sum of the angles is found to equal 180 degrees. Students also investigate quadrilaterals.

Young scholars explore geometric vocabulary through creation of shapes on a geoboard. They present design attributes, transfer of design, and color-coding components mix to create a fun and exciting lesson that stretches student thinking.

Pupils calculate the area of figures using the formula: length x width = area. They solve area problems using paper squares, geoboards, and real-world problems.

Sixth graders explore lines and angles. They create visual representations of lines, rays and angles by drawing them on paper and using a geoboard. On paper, 6th graders write a summary of the characteristics of their representations.

First graders identify and create the fractions one-half and one-fourth. The teacher first demonstrates how to create the fractions on a geoboard. The students then create one-half and one-fourth of a square, triangle, and a rectangle on...

Third graders recognize geometric shapes with acute angles, make geometric shapes with acute angles on geoboards, and draw acute angles on geopaper.

Students review angles, sides, and properties of basic shapes. Using a geoboard, they make as many different tirangles as possible.

Fourth graders examine halves of a whole and discover through activities that they must be exactly equal in size. Working with Geoboards and Dot-Paper Squares, the class practices finding halves that are both congruent and incongruent.

Pupils use interactive geoboards to identify simple geometric shapes. In this making triangles instructional activity, students describe the properties associated with geometric shapes. Pupils develop spatial sense and the...
