Geometry

During the first quarter, we learned about two-dimensional shapes, focusing on polygons such as triangles, quadrilaterals, pentagons, and hexagons.  We used geoboards, pattern blocks, and shape sort cards to help us build, sort, label, and describe 2-D shapes.  Some of the key vocabulary words we used to describe our shapes were:  sides, angles, and vertex, and parallel. 

We reviewed how "tri" means "three" and we brainstormed a list of "tri" words, such as:  triangle, triceratops, tricycle, tripod, and Triwizard Tournament.  We also discussed whether all squares are rectangles and if all rectangles are squares.

Students seemed to enjoy this hands-on mini-unit.  We will return to our study of geometry in December to learn more about two- and three-dimensional shapes.
