"The Greedy Triangle"

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...

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...

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

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

Elementary schoolers explore shapes and their attributes by accessing websites, story books, and by using manipulatives. A very clever story called The Greedy Triangle, is used to foster learning, as are some fine worksheets, and...

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 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.

 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.

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...

Third graders recognize basic geometric shapes. In this literature and math lesson, 3rd graders listen to The Greedy Triangle and make predictions about what the triangle will become. Students read ten clues about a mystery animal made...
