5. Accurately create more than one distinct net of a cube using
concrete cube manipulatives, in a group activity
(Affective Domain)
6. Participate willingly in a group activity to discover the net of a
cube
PREVIOUS KNOWLEDGE, SKILLS AND EXPERIENCES:
1. Students are able to identify prototypes of the 3 dimensional figures: cubes, cuboids,
cylinders, prisms, cones and pyramids.
2. Students know the properties of a square.
3. Students are familiar with the following terms related to a cube: face, edge,
vertex/vertices
MATHEMATICAL PROCESSES:
1. The students have to engage in the activity, in a given amount of time, of creating more
than one examples of net of a cube. Students cooperate to discover ways to get multiple
3
nets. This task involves the problem solving process with the use of concrete
manipulative where students engage in visualisation and inventiveness among other skills
to find more than one solution to the same problem (more than one net of a cube).
Students have the freedom to use more than one strategy to solve the problem.
2. The activity to create more than one net of a cube requires the students to recognize
structures of the nets which may or may not result in a cube. Students are required to give
reason(s) in attempting to distinguish which net gives a cube. This develops their
reasoning skills. The group activity encourages students to critique each other’s
suggestions in their groups and formulate full-proof methods in proving their answers.
Since each group is required also to explain their solutions reasoning skill is further
developed.
3. The lesson builds on students’ prior knowledge of understanding the nature of 3
dimensional figures and how it makes it possible to derive a net from a cube. By referring
to cardboard boxes, which are items in their real life, students will make connections to
what they already know and effectively develop their mathematical understanding. The
new knowledge of “nets of a cube” is not learnt in isolation and will most likely be
imbedded in long term memory.
4. The use of multiple representations of the cardboard box by demonstration (concrete
manipulative) and the diagram of it on the whiteboard provide students with more than
one way of deriving the attributes of a cube. Drawing the discovered nets on the
checkered grids provided when they are given the 3” X 3” cubes provides them with the
opportunity to use representations to record the idea of “nets of a cube”
4
5. Demonstration of solution(s) in the activity and including the journals in the lesson
provides the students with experiences of multiple ways of expressing mathematical
understanding. Apart from demonstrating, students communicate their ideas when they
write and explain their method(s) used in deriving nets of a cube.

SET INDUCTION:
TIME ALLOCATION 1: 3 Minutes
Bring students to the floor. Ask, “Who can say what an attribute is?” Confirm that an attribute
describes a quality, property, or characteristic of somebody or something.
Call on a student to stand in front of the class and state an attribute/property of the child (the
color of their hair, eyes, shoes, etc.). Ask students, “What are some other attributes (or
properties) of … (name of student). Students contribute suggestions.
MAIN IDEAS/ UNDERSTANDINGS/FOCUS

The properties of a cube are: Cubes have twelve edges, eight vertices and six faces which
are squares

The net of a 3 dimensional object is
STEP- BY STEP PROCEDURES/ACTIVITIES IN THE LESSON
SECTION ONE – 12 Minutes

Introduce the alternative words to “attributes”: properties, characteristics, qualities.

Ask students, “Who can recall the names of the different three dimensional figures you
learnt about in last class?” Pause a few seconds then call on student(s) in class to list
them.

Let students know that the main focus of the lesson is on Cubes, their properties, and
their nets. Show students Figure 1 on the slide show (see Appendix) which shows various
3D shapes and ask, “Which shape shown is a cube?” Ask a student who raises his/her


Reveal to students a large cube- shaped cardboard box to demonstrate an example of
where in the real world a cube can be found. Ask students, “What else (in the real world)
has the shape of a cube?” List at least Three (3) examples given by students on the
whiteboard. If students are unable to give examples, three are
 Die (plural Dice)
 Ice cubes
 Rubik’s Cube

Distribute one cube each to the students and ask them to identify the different properties
of the cube, making sure they call the “sides” faces, and “corners” vertices.
Prompt students with the questions, “What can you tell me about
 the faces of the cube
 the edges of the cube
 the vertices of the cube?”

As students identify the properties compile a list on the whiteboard. When all properties
are listed allow students to write them in their math notebooks. Ensure the following
properties are included:
Cubes have
 twelve edges,
 eight vertices and
 six faces
 all faces are squares

To reinforce the properties of a cube show a number of projected images of mixed
examples and non-examples of cubes. Students must analyse which are cubes/not cubes,
and say why. Pose questions to the entire class then randomly choose students to give
responses.
Ask the following questions for each image:
1. Is this a cube?
2. Why do you say so?

SECTION TWO – 20 Minutes
Activity

Place students in groups of three’s for the purpose of the activity.

State the objective of the activity – To Investigating the Net of a Cube
Give students the definition of what is a Net. Then ask students, “Given the definition of
a Net, what do you think is the net of a cube?” Write their definition at the top of the
Whiteboard. Allow students to take note of the definition in their notebooks.

Let students know that they will now follow three simple steps in which you start with a
cube and derive its net. They will work in their groups of three’s and use ONE cube per
group. Use the prepared comprehensive steps shown on the power point slides for
students who cannot understand clearly by listening. An instruction sheet is distributed as
well for each student.
INSTRUCTIONS:
Step 1.
Place the cube on a flat surface (the desktop/table-top).
Identify the top flat face of the cube.
Using a pair of scissors, cut three edges around the face to make a flap (see Step 1
diagram)
Step 2.
Cut along the four vertical edges downwards until you reach the base of the cube.
Hold the flap and open outwards (see diagram)
Step 3.
The cube can now be opened completely to the form of its net (see diagram)
Demonstrate how the net is formed back into a cube by folding.

Let students know that it is possible to get eleven (11) distinct nets of a cube.

Students in each group now work together to create different nets of a cube, Each group
is allowed three cubes. Instructions given:
 Students can cut ONLY edges
 ALL faces must be joined together by at least one edge each
9
 Every student must participate
 Groups are given five (5) minutes to create their nets.

Presentation of Findings

Students, in their groups, display their nets by sticking them on different sections of the
whiteboard. Label each group’s work.

Possible questions to ask group members:
 How do you know that you have created a net of a cube?
 Was there any special method that you used to arrive at your nets?
 Did you make any other observations when you
 Can you draw a net of a cube without using the cube?
 Is it possible to create a new net of a cube without using the cube? How?
 Why do you think we need to learn about Nets?

Confirm that all nets are accurate. Allow students to draw the different nets of a cube that
they created, on the Grid Sheet provided.
