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.

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.

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...

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

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...

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

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.

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

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

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...

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 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.

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...

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 instructional activity! 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....

Learners 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.

First graders sort toys by various attributes. They, in groups, sort toy vehicles by color, size etc. and then explain how they chose to group the toys. They write, draw or dictate an explanation of their sorting methods.

Students 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 attribute...

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.

Students listen to a story "My Crazy Dream" with an intent to identify shapes in ordinary objects. They raise their hands when they've heard an object whose shape they can identify. They discuss their findings.

Ninth graders play guess my shape (either describe or use a feely bag to introduce the 3 shapes in the problem.) As they are identified put them in an order as shown in the problem. As the students work on the problem in pairs teacher...

Learners explore a calendar. In this calendar and math instructional activity, students view a video clip about using a calendar. Learners participate in a game in which a game board is used to identify days of the week, dates, and months.

Second graders write a Math Moments journal.
