Students have been learning about the following skills/concepts in Geometry.

Transformations: A transformation is a rule that results in a change of position, orientation or size. They include translations (slides), reflections(flips) or rotations (turns).

Reflections: A flip of a 2D shape; each point in a 2D shape flips to the opposite side of the line of reflection, but stays the same distance from the line.

Translation: A slide of a shape; the slide must be on a straight line.

Rotation: a turn of a 2D shape; each turn can be identified as a 1/4, 1/2, 3/4 or full (1) turn.

Congruent: When a shape is congruent it means it is identical in size and shape. In order to be sure a shape is congruent you can check 2 ways.

1) tracing paper – trace the shape, cut out, match to other shape

2) Ruler + Protractor – Measure all side lengths and angles to see if they are identical.

Prism: A 3D shape with opposite congruent bases. The other faces are parallelograms (usually rectangles).

Pyramid: A 3D shape with just one polygon for a base. The pyramid is named for the shape of it’s base. The other faces are triangles and meet at a single vertex. (eg: square based pyramid)

Net: A net is a group of 2D shapes that you can fold to create a 3D solid. Students should be able to draw nets for 3D solids and identify which 3D shapes can be made from a net.
