In this geometry lesson, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...

Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.

Primary geometers create a picture using tangrams. In this geometry instructional activity, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their...

Play a coordinates game to encourage collaborative learning and grid use! Learners plot points on grids and play a game that challenges them to locate a specific point on a coordinate grid by using horizontal and vertical movements.

Learners identify and explore the attributes of polygons. They design and create a quilt square using polygons, and produce a class quilt.

Students learn five songs to define and develop understanding of the attributes of two- and three-dimensional figures and the meaning of mathematical terms. They classify objects as either two- or three-dimensional, through the use of...

Second graders culminate their study of shapes by describing the shapes using the proper mathematical descriptors.

First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.

Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.

Students add to a class Shape City by designing and constructing new buildings.

What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Young scholars compare and contrast related two- and three-dimensional shapes, and complete a Venn diagram illustrating the attributes of each. Using a poem pattern from another lesson, students use data from the diagram to write an...

All disciplines use data! A seven-lesson unit teaches learners the basics of analyzing all types of data. The unit begins with a study of the shape of data displays and the analysis of a normal distribution. Later lessons discuss the...

Students view animals that camouflage at the Shedd aquarium website. For this camouflage lesson, students recognize that there are different types of camouflage, cryptic coloring, counter-shading, warning coloration and mimicry. Students...

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...

Here is a real-life lesson! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore what...

Pupils 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.

Young learners listen to a read aloud of Gail Gibbons book, Apples and the story A Red House With No Windows and No Doors. They compare characteristics of a number of kinds of apples, graph them and create a apple print picture. Learners...

Fifth graders inquire as to why scientists use observable characteristics, how they sort the characteristics, and why they do so. They write journal entries to be used throughout this unit.

Students examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.

Discover the difference between standard and non-standard units of measure with your class. They differentiate between rectangles and squares, read a book, measure a peer's height. They then discuss  measurement methods, make...

Let's go fly a kite! Discuss the concept of two-dimensional and three-dimensional objects with your math class. They examine a triangle and discuss the face, vertices, edges, and angles. Then they build their own Tetrahedral Kites and...

Second graders explore how musical instruments h ave varying geometric shape, and how those geometric shapes correspond to three-dimenaional shapes that students have studied.
