We are beginning 2D Geometry before the holidays. We will then move on to 3D figures. The expectations are as follows:
- I can identify and compare various polygons (triangles, quadrilaterals, pentagons, hexagons, heptagons, octagons) and sort them by their geometric properties (# of sides, side lengths, # of interior angles, # of right angles)
- I can use a reference tool to identify right angles and to describe and compare angles as greater than, equal to, or less than a right angle
- I can compare and sort prisms and pyramids by their geometric properties
- I can construct rectangular prisms and describe geometric properties of prisms
- I can solve problems requiring the greatest or least number of 2D shapes needed to compose a larger shape in a variety of ways
- I can explain the relationships between different types of quadrilaterals
- I can identify and describe the 2D shapes that are found in 3D shapes
- I can describe and name prisms and pyramids by the shape of their base
- I can identify congruent 2D shapes by manipulating and matching concrete materials
