2D Shapes



In our geometry unit the students have been exploring the attributes of different two dimensional shapes.  They began filling designs using different 2D shapes. They had to count and record the shapes used.  The students learned that shapes can be decomposed into different shapes.  A hexagon can be made using 2 trapezoids or 6 triangles.  They then composed the same design three times using different combinations of shapes.  Finally they tried to fill a design using a few shapes and then using a larger number of shapes.
