Lesson Topic: Drawing 3D objects
Geometry
Recent Prior Experience: Last lesson students looked at 3D objects and discussed their edges, corners and faces. Students modelled various 3D
objects with play-doh.

Indicators of Learning for this lesson:
Assessment:
- SGS1.1 Models, sorts, describes and
represents three-dimensional objects
including cones, cubes, cylinders, spheres and
prisms, and recognises them in pictures and
the environment.
By the end of this lesson, the students will:
- identifies and names cones, cubes, cylinders,
spheres and prisms and describes their
properties.
- represent three-dimensional objects through
simple drawings.
Any safety issues to be considered:
Resources:
Worksheet - page 62
3D objects - cube, cylinder, rectangular prism.
Whiteboard and marker OR blackboard and chalk.
A3 photocopy of students’ worksheets.
- Students identify and name a range of threedimensional objects and describe their
properties.
- Students trace outlines for threedimensional objects and also draw these
objects without the outline.

Mystery Object/Who Am I?
T lists attributes of various 3D objects for students to
identify the object and name it. Ss to perform actions when
they know the answer (e.g. hands on head, hand in air).
Examples of statements about 3D objects:
- I have 6 faces
- All my faces are the same.
- I have only one curved surface.
Ss identify 3D objects based on
their properties.
-
Development
A cube has 6 faces, which are
shaped as a square.
Ss describe properties of threedimensional objects.
Ss lists the steps needed to draw
3D objects.
A cylinder has 2 faces and 1
curved surface.
A rectangular prism has 6 faces
which are shaped as a rectangle.
25
minutes
I have a curved surface which meets at a point.
I have two ends which are circles and one curved
surface.
Looking at the worksheet, what is the first object on the
sheet? How many faces does this object have? What is the
shape of each face?
Ss use their pointers to draw a square.
T: The first thing we need to do to draw a cube is draw a
square - draw square on board. Again Ss draw a square using
their pointers.
To make this two-dimensional square a three-dimensional
cube we:
- First draw a square (draw over square on board).
- Second, draw a second square behind the first one.
- Then we connect the matching corners.
Have Ss hold up their left hand, their right hand. Ss to point
to the top and bottom.
- So, you have to connect the top left corner of the
first square with the top left corner of the second
square. (Repeat with other corners).
Using enlarged A3 worksheet, demonstrate the above
procedure with the dotted outline of the cube.
Quiz students about the order of the steps.
Once Ss have traced the first shape, look at the second 3D
object. What is the object? How many faces does it have? It
has one curved _____?
To draw a cylinder:
- Draw a circle.
- Draw another circle below it.
- Draw two lines from the outsides of the circles.
Using enlarged A3 worksheet, demonstrate the above
procedure with the dotted outline of the cylinder.
Quiz students on the order of steps for drawing a cylinder.
Look at the third object on the worksheet. What is the
object? How many faces does it have? What is the shape of
the faces?
Drawing a rectangular prism is very similar to drawing a
Have book monitors hand out
worksheets to students at
their desks. Remind Ss to put
their names and date on their
sheet.
Pencils down, pointers only at
this point.
Ss to follow demonstration
with their pointers.
Ss to follow on their
worksheet and draw the lines
that T draws.
Ss to draw on their
worksheets, tracing the
outline.
cube. Who can tell me what we might do differently?
steps for drawing a rectangular prism:
- Draw a rectangle.
- Draw a second rectangle behind the first one.
- Connect the matching corners.
Using enlarged A3 worksheet, demonstrate the above
procedure with the dotted outline of the rectangular prism.
Quiz students on the order of steps for drawing a
rectangular prism.
Ss are to return to the top of the sheet and trace over the
shapes already completed. Ss are to then attempt to draw
the shape on the next outline working their way down the
sheet. When finished Ss can turn their page over and try
drawing cubes, cylinders and rectangular prisms by
themselves. Explain to Ss that the T will write the steps for
drawing these objects on the board if they need reminding.
Closure
Ss represent 3D objects through
air drawing.
3
minutes
Recap with Ss the order for drawing cubes, cylinders and
rectangular prisms. While going through steps, Ss draw
objects with their pointers.
Ss to re-trace in a different
colour
Book monitors to collect
sheets and place on the
marking table.
