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...

Young scholars examine spider webs they find as they explore outside. They make T-chart of the shapes found in two different webs and draw them on geoboard paper. Next, they measure length and width of a spider's web before checking to...

Fifth graders identify the area and perimeter of a rectangle. In this perimeter lesson, 5th graders use geoboards and rubber bands to construct various rectangles. Students use the formula to calculate area and perimeter of the...

Second graders use geoboards to model polygons and to practice finding lines of symmetry.

Students create pictures using a geoboard and straws using the X and Y axis.

Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...

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 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.

Fourth graders use math software and geoboard paper to design basic shapes. They write individual definitions for the geometric shapes based on what they see in the shapes. They apply their background knowledge of the shape as they write...

Fifth and sixth graders engage in a series of activities which show them the importance of using different types of measurement strategies. One of the primary goals of the instructional activity is to show learners that measurement is...

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. 

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Add up areas of squares to discover the pythagorean relationship. Small groups create right triangles with squares along each side. They calculate the areas of each square and notice the relationship. Groups construct other types of...

Point your class in the right direction in plotting points with three activities that give scholars a chance to learn about and practice plotting points on a coordinate plane. They draw figures on the coordinate plane and list out the...

Introduce the day's lesson by reading Jack and The Beanstalk by Richard Walker, and then review the concept of area with your class. We don't always need rulers to measure, though! Teach learners how to use their hands to help us measure...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Upper graders identify the surface area and attributes of figures that are measurable. They estimate, measure, and record perimeter, area, temperature change, and elapsed time, using a variety of strategies. They also determine the...

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this lesson. They make a set of tangrams and use them to compute area. They use...

Learners find the area and perimeter of regular polygons and composite figures and examine the effect on the area and perimeter of a figure if the dimensions are multiplied by a constant. The nine page worksheet contains thirty-seven...

Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

First graders listen as the book, "Try It With Triangles" is read to the class. They name the geometric shapes that they see in the story and view the Shape Vocabulary Cards as they name them from the book. They then cut out the...
