Continuing our math focus on geometry while emphasizing our new phonetic pattern, r-blends, 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. Bringing the book to life, students conducted a classroom shape hunt, graphing their findings. They used toothpicks to build examples of quadrilaterals and played a 2-dimensional shape version of “I Have Who Has.” Centers throughout the week will continue to incorporate a variety of activities and manipulatives supporting exploration, identification, classification, and construction of two-dimensional shapes.
