The Greedy Triangle

Continuing our math focus on geometry, today we read aloud The Greedy Triangle by Marilyn Burns.  Throughout the book, students were exposed to new vocabulary and real life examples of shapes.  Wanting more and more sides, the greedy triangle repeatedly visited the shapeshifter, changing into a quadrilateral, pentagon, hexagon, heptagon, octagon , nonagon, and decagon.  In the end, however, the triangle decided he was most happy when he was himself, and he returned to life as a triangle.   Centers this week will incorporate a variety of manipulatives allowing students to explore, identify, classify, and construct two-dimensional shapes.
