Geometry is Great!
We have been exploring 2D shapes in our classroom using a variety of math materials.Students have been especially focused on the geometric attributes of each shapes - the number of sides and the number of vertices (corners) that each shape has.
We have noticed different kinds of triangles, but they ALL have 3 sides and 3 corners.
We were surprised by how many different shapes have 4 sides and 4 corners. We learned that these shapes have specific names (square, rectangle, rhombus, trapezoid, parallelogram) but that they are ALL called 'quadrilaterals' because they have 4 sides/corners.
We also learned the properties of pentagons, hexagons, heptagons, octagons, nonagons and decagons.
As always, we are playing a lot of games to reinforce new vocabulary and to provide practice identifying, creating, comparing and thinking about the 2D shapes.
