Students are starting a new math unit on two-dimensional geometry.
In this unit, students will:
– use a reference tool to identify right angles and to describe angles as greater than, equal to, or less than a right angle
– compare various angles, using concrete materials and pictorial representations, and describe angles as bigger than, smaller than, or about the same as other angles
– identify and compare various polygons (i.e., triangles, quadrilaterals, pentagons, hexagons, heptagons, octagons) and sort them by their geometric properties (i.e., number of sides; side lengths; number of interior angles; number of right angles)
– explain the relationships between different types of quadrilaterals (e.g., a square is a rectangle because a square has four sides and four right angles; a rhombus is a parallelogram because opposite sides of a rhombus are parallel)
– complete and describe designs and pictures of images that have a vertical, horizontal, or diagonal line of symmetry.
You can support your child at home by discussing various shapes and their attributes.
