The Greedy Triangle Teacher Resources

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), partners form the various shapes...

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

Learners read The Greedy Triangle and discuss geometric solids. In this geometry lesson, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

Fourth graders recognize and classify geometric figures. In this geometry lesson, 4th graders read the books Shape Up and The Greedy Triangle and prepare a short report on the shapes mentioned in the text. Students compare the polygons...

Learners discuss figures with various numbers of sides.  In this geometry lesson, students are read The Greedy Triangle by Marilyn Burns, they participate in a class discussion of many sided figures and are introduced to the term...

Third graders use the book "The Greedy Triangle" to practice measuring perimeter and area. They also calculate the length of objects.

First graders explore geometry by reading a story with their classmates. In this shape identification lesson plan, 1st graders discuss the differences between two and three-dimensional figures and identify the characteristics of common...

Students demonstrate their comprehension of shapes and their properties. They work in small groups. Students review the following terms: property, polygon, quadrilateral, and parallelogram. They read Shape Up! Fun With Triangles and...

Students investigate geometric shapes. In this geometry instructional activity, students read the book The Greedy Triangle and define the shapes mentioned in the book. Students make the shapes by using their bodies.

Students explore different shapes and identify them. They make a community map using triangles, rectangles, circles, ovals, squares, pentagons, and hexagons.

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy Triangle,...

Investigate the area and perimeter of polygons in this geometry lesson. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape of...

Young learners listen to the story book The Greedy Triangle as the teacher introduces new polygon shapes. They use geometric stencils to trace a quadrilateral, a pentagon, a hexagon, and an octogon onto a foldable notepad. They identify...

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

Students discover which regular polygons can be used to tile a plane.

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 paper.

First graders listen to Shapes and The Greedy Triangle to identify and describe examples of geometric shapes.  In this geometric shapes lesson, look for geometric shapes in real world places.  Students make a mobile of shapes in the real...

Young scholars explore geometric solids. In this geometry lesson, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Young scholars define geometric...

Two young scholars are blindfolded and each receives a cardboard square, one with pompoms glued around the edge and one with pompoms glued all over the surface. They identify what they feel. The class discusses perimeter and area of...

Third graders name different kinds of shapes and then discuss what they know about them an what they would like to learn using a K-W-L chart whole group. They listen to the book, THE GREEDY TRIANGLE and then retell it to the class. They...

First graders draw and describe various types of polygons. they investigate their own environments for examples of polygons. After reading the book, The Greedy Triangle, they discuss everyday objects that are polygons. They create shape...

Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber bands...

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...

Explore the concept of creating and describing 2D and 3D shapes.  Using geometry your scholars will describe the attributes of shapes and their properties.  They explore and discover what happens when you combine shapes and then take...
