Lesson 1

Students will be able to describe different shapes

Face: part of an object (all the surface area)

Edge: where 2 faces of a solid meet (where 2 sides meet)

Vertex: the point where 2 sides meet or

the point where 3 or more edges meet (or 3 sides)

Lesson 2

Students will be able to understand perpendicular sides

going up or down

Perpendicular: where a horizontal edge and vertical edge intersect to form a right angle

OR

when two sides of any shape intersect to make a right angle

Right Angle: 90’ symbol is a box in the corner

Vertical
