# Geometry

## 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 3-D shapes.

## Geometry topics for kindergarten to grade 5

• identify classify 2-D 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 two-dimensional shapes (transformations)
• identify 3-D 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.
