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....

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...

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...

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.

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,...

Students identify lines of symmetry.  In this symmetry instructional activity, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Students cut shapes out of...

Students explore similar objects. They participate in a series of hands-on, multimedia and online activities to examine how the edge length affects the angle measures, perimeters and areas of similar regular polygons. Students find the...

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...

Learners practice finding the areas and patterns within a square and explore the concept of quadratic functions. They observe and record the area values in a table, plot a graph of Area versus Distance and complete a variety of student...

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.

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.

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.

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.

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...

Eighth graders explore congruent and similar figures.  In this eighth grade geometry instructional activity, 8th graders use geoboards to create congruent and similar figures and explore the relationships between the sides and...

First graders investigate symmetry in patterns by utilizing unifix cubes.  In this pattern lesson, 1st graders practice creating patterns that are perfectly symmetrical no matter which way it's looked at.  Students utilize...

Students work in pairs, to make a square on the geoboards with a rubber band (or draw one on the dot paper). It can be any size and in any location and share their answers with the class.

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...

Excellent lesson! Anne Linehane's geometry story, The Greedy Triangle, offers an opportunity to practice forming various types of polygons with your learners. Using elastic bands (or Chinese jump ropes),...

Young geometers use the interactive website Cyberchase to practice calculating both area and perimeter. Real world problems encourage learners to discover that we use math each and every day.
