# LESSON PLAN: Learning 3D Shapes with Magna-Qubix®

### Teach children how to identify 2D and 3D shapes with Magna-Qubix®!

** Common Core Objectives:** Analyze and compare two- and three-dimensional shapes in different sizes and orientations, using informal language to describe similarities, differences, parts (e.g., number of sides and vertices/”corners”) and other attributes (e.g., having sides of equal length). K.G.B.4

Understand the relationship between numbers and quantities, connect counting to cardinality. K.CC.B.4

**Objectives:**

Students will:

– Name the following three-dimensional shapes: cube, square pyramid, triangular prism, hexagonal prism and rectangular prism.

– Count and say the number of sides and vertices each shape has.

Materials: 1 set of Magna-Qubix®

Directions:

** #1.** Hold up the Magna-Qubix® cube. Ask if any students know the name of the shape. If nobody knows that it is a cube, tell the students the name of the shape.

** #2.** Explain to the students that each flat surface of the cube is a side of the cube and that each corner is a vertex. Also explain to the students that more than one vertex is called vertices.

** #3.** Together, count the number of sides the cube has (answer: 6) and the number of vertices (answer: 8).

** #4.** Hold up the Magna-Qubix® square pyramid. Ask if any students know the name of the shape. If nobody knows that it is a square pyramid, tell the students the name of the shape. Explain to the students that it is called a square pyramid because it has a square on the bottom of it which is called the base.

** #5.** Together, count the number of sides the square pyramid has (answer: 5) and the number of vertices (answer: 5).

** #6.** Hold up the Magna-Qubix® rectangular prism. Ask if any students know the name of the shape. If nobody knows that it is a rectangular prism, tell the students the name of the shape. Explain to the students that it is called a rectangular prism because it has rectangles that make up the sides.

** #7.** Together, count the number of sides the rectangular prism has (answer: 6) and the number of vertices (answer: 8).

(** Note:** If you have enough Magna-Qubix®, you can have small groups of students count the number of sides and vertices and then one person from each small group can give the answer.)

**Extension:**

Allow small groups of students to explore the Magna-Qubix®. Ask them questions about how the shapes are the same and how they are different.

**Example Questions:**

– What shapes are the sides of the cube? (answer: squares) Is there another shape that has a side that is a square? (answer: square pyramid and rectangular prism)

– What shapes are the sides of the square pyramid? (answer: a square and triangles) Is there another shape that has a side that is a square or a triangle? (answer: cube and rectangular prism have sides that are square)

– What shapes are the sides of the rectangular prism? (answer: rectangles and squares) Is there another shape that has a side that is a square or a rectangle? (answer: cube and square prism have sides that are square)

**Assessment:**

– One-on-one, hold up a shape and have a student tell you the name of a shape.

– For a group assessment, hold up a shape and have the students write how many sides and how many vertices the shape has.
