Lesson Plan
Performance Objective
At the end of the lesson, students will able to sketch/trace/draw the six views of their own smart phone. They
will draw the measurements needed and precisely measure them using a vernier dial caliper to match the
criteria in the “My Smart Phone” Sketch/Trace/Draw Rubric. The drawings and parts will be used to create a
3D model of their own phone to match the criteria in the “My Smart Phone” 3D Model Rubric
Specific Objectives
 Sketch/trace/draw the six views correctly on the 11 x 17 graph paper
 Measure precisely the phone
 Create a 3D model of their phone
Terms
 Caliper- usually referred to as calipers, is an instrument for measuring thicknesses and internal or external
diameters inaccessible to a scale, consisting usually of a pair of adjustable pivoted legs.
 Vernier Dial Caliper- is a caliper formed of two pieces sliding across one another, one having a graduated
scale, and the other a vernier; also called vernier micrometer.
 Six (6) Parts of a Vernier Dial Caliper- include nibs, slide assembly set screw, jaws, dial, thumb screw, and
dial set screw. (See diagram.)

Preparation
• Students should have completed the Paper Vernier Dial Caliper lesson and passed the test with 80% or
better before proceeding with this lesson.
• If your budget does not allow for real dial calipers, you can substitute a divider or compass and
measurement scales.
• There are two options for students who may struggle with this lesson:
 Give them the drawings with measurements found in the presentation.
 Let the student work with a stronger student and make it a team project.
• It should take students one to two days to sketch/trace/draw the six views of their smart phone.
• It should take students approximately two to three days to precisely measure all the parts of the six
views of their smart phone.
• It should take students approximately five to six days to 3D model all the parts of their smart phone
and assemble it.

Introduction
The purposes of this lesson is to allow students time to sketch/trace/draw the six views of their own smart
phone, draw all the measurements needed and precisely measure them using a dial caliper, and use the
drawings and parts to create a 3D model of their own phone.
Days 1-2
 Show
o “My Smart Phone” examples and “My Smart Phone” Precision Measured Drawing and 3D Model
slide presentation
 Say
o This is what you will be working on these next two to three weeks.

Ask
o Why do you think this time we draw all six views and not just the standard two to three?
o Answer: Because it is so in-depth and has so many varying parts, it requires all six views.

Ask
o How do you think you should start or lay this out on the 11 x 17 graph paper?
o Answer: Start by tracing the outline of your phone.
o Answer: Show them the slide presentation and example.

Say
o Now it is time for you to sketch/trace/draw the six views of your smart phone.
Days 3-5
 Ask
o What can you measure your smart phone by, using the dial calipers? English standard or Metric?
o Answer: You can use either English standard or Metric, just make sure you use the same
throughout.

o Examples of what the hand drawn six views should look like (Slides 5-8)
o Examples of what the 3D modeled assembly looks like with dimensions (Slides 35-38)

Say
o We will spend the rest of our time these next two to three days drawing and dimensioning your
smart phone using the dial caliper.
o Walk around the room to check student’s progress
Days 6-11
 Say
o Today you will start to 3D model you smart phone.
o Remember to break it down into all of its parts, and then assemble them.
o Refer to the examples so you have an idea of what it should end up looking like.
