Lesson: Classifying Solids
Display two different shapes: Triangle and Square. Ask the students to describe each figure listin all of its properties.
Allow students to share their answers and demonstrate if possible.
Exploration (Self- Guided) 10 min.: (Notes)
Solid figures have 3 dimensions: length, width, and height.
Face: the flat surface where the edges meet.
Edge: the line segment that connects two faces and two vertices
Vertex: the corner or point where edges meet.
Explanation (Insrtuctional) 15 minutes:
Teacher will display actual three dimensional solids so that students can see how each looks and identify the properties of each.
Cube: 6 Faces/ 12 Edges/ 8 Vertices
Students will create actual three dimensional figures to see what each part of the solid looks like and make a connection to real world items.
