Grade 1 - Geometry and Spatial Sense
Standard 1.GSS.1 - Count and compare sides and corners of two dimensional shapes determining which shape has more or fewer.
Included Skills: Geometry
Geometric Properties • identify and describe common two-dimensional shapes (e.g., circles, triangles, rectangles, squares) and sort and classify them by their attributes (e.g., colour; size; texture; number of sides), using concrete materials and pictorial representations (e.g., "I put all the triangles in one group. Some are long and skinny, and some are short and fat, but they all have three sides."); • trace and identify the two-dimensional faces of three-dimensional figures, using concrete models (e.g., "I can see squares on the cube."); • identify and describe common three-dimensional figures (e.g., cubes, cones, cylinders, spheres, rectangular prisms) and sort and classify them by their attributes (e.g., colour; size; texture; number and shape of faces), using concrete materials and pictorial representations (e.g., "I put the cones and the cylinders in the same group because they all have circles on them."); • describe similarities and differences between an everyday object and a three-dimensional figure (e.g., "A water bottle looks like a cylinder, except the bottle gets thinner at the top."); • locate shapes in the environment that have symmetry, and describe the symmetry.
