Quad-ri-lat-er-al is a pretty biiig word for a First Grade student, but a pretty easy concept to understand. A quadrilateral is simply a polygon with 4 sides. This means any 2-D shape such as the ones pictured below. The table below shows the quadrilaterals we know from exploring with our pattern blocks. Just like when we explored with triangles, the main goal for this lesson was to make sure students understand what a quadrilateral is and to create different types of quadrilaterals on their Geoboards. Our friends totally blew this exploration out of the water!
