Geometry: from shapes to transformations
Geometry is a highly visual subject. Our geometry resources begin at the kindergarten level with recognizing simple shapes such as triangles, circles and rectangles and proceed through grade 5 level geometry, including coordinate geometry and analysis of 3D shapes.
Geometry topics for kindergarten to grade 5
 identify classify 2D shapes including triangles, quadrilaterals and circles
 properties of circles
 properties and classification of angles and triangles
 understand spatial relationships (in and out, above and below, etc.)
 subdivide and combine shapes into new shapes
 decompose 2D shapes to develop concept of fractions
 understand the concepts of perimeter and area
 understand congruence, similarity and symmetry
 points, segments, rays and lines
 recognize parallel and perpendicular lines
 coordinate geometry (e.g. find locations on a grid; the four quadrants)
 predict the results of sliding, flipping, and turning twodimensional shapes (transformations)
 identify 3D shapes
 surface area and volumes of rectangular prisms
 identify lines of symmetry and rotational symmetry in 2D shapes.
 build 3D objects from 2D representations
 draw 2D representations of 3D objects.
