Three-Dimensional Solids

Designed by: Sally Hug, Hand Middle School

GRADE LEVEL: 8th     SUBJECT(S): Math

CORE CURRICULUM OBJECTIVE(S): Name, identify, and compare 3-d solids according to one or more attributes. (8GE1-2)

 RESTATEMENT: Students will name and find given characteristics of 3-D shapes.

OVERVIEW: Students will use concrete objects to name and give characteristics of 3-D shapes. These characteristics include faces, edges, and vertices.

FOCUS/ ESSENTIAL QUESTION(S): What are the names of three-dimensional shapes? What are the characteristics of these shapes?

TIME FRAME: Three - Four 45-50 minute periods - one or two periods for building shapes - one period for class discussion - one period for review and game

RESOURCES: 
- Gateways to Algebra and Geometry (p.573 & 575), for reference 
- Data gathering sheets 
- Rubric 
- Paper/ Pencil 
- Overhead copy of data gathering sheet 
- Glue 
- Scissors 
- Colored pencils/crayons/markers 
- Copies of cut and fold shapes 
- Teacher set of prisms and pyramids (these can be food boxes, cans, real life examples.) 
- Sandwich bags

ASSESSMENT: Students will name and give characteristics of 3-D shapes by creating actual three dimensional shapes.

INSTRUCTIONAL ACTIVITIES:

ACTIVITY ONE 

* The teacher will provide copies of the fold and cut shapes sheet (below). The students will color, cut, fold and glue their 3-D shapes together. 

* Properties of these shapes will be discussed later. 

* Each student will be given a sandwich bag to place finished shapes or shapes to be finished in the bag. 

* Shapes will be displayed.

ACTIVITY TWO: 

* Students will have a class discussion, lead by the teacher, and fill together fill in the chart below. The discussion will include how to name these shapes and what the different attributes of these shapes are and how many there are. 

* Prisms: where the shape does not come to a point; the bottom face and the top face are the same:

* Pyramid: where the top comes to a point 

* To name a shape: 
1) name it first by the base 
2) by the top either prism of pyramid Vertex: corners (8 vertices)

this is a square prism:

 * As shapes are reviewed, the chart should be completed together and the students should keep a copy.

Data chart:

ACTIVITY THREE: 

* The students will review names of shapes and the attributes of these shapes. 

* The teacher will lead a class review of learned material so far by playing a game. A students will stand, the teacher will hold up a shape and ask a question (What is this shape's name?, How many faces?, How many vertices?). The teacher will go around the room and a student will sit down if the question is missed. 

* The teacher will assess student (if needed). Assessment below. Students will fill in chart. Students can use their shapes if needed.

Name of shape: Shape of base # of faces # of edges # of vertices
