Preparation
TEKS Correlations:
This lesson, as published, correlates to the following TEKS. Any changes/alterations to the
activities may result in the elimination of any or all of the TEKS listed.
Engineering Design and Presentation:

130.365(c)(1)(E)
…identify and use appropriate work habits.

130.365(c)(3)(B)
…complete work according to established criteria.

130.365(c)(5)(A)(B)(F)
…sketch single- and multi-view projections.
…prepare orthographic and pictorial views.
…construct true length of lines and true size of planes by the revolution method.
Interdisciplinary Correlations:
English Language Arts and Reading, English IV:

110.34(b)(1)(A)(E)
…determine the meaning of technical academic English words in multiple content areas
(e.g., science, mathematics, social studies, the arts) derived from Latin, Greek, or other
linguistic roots and affixes;

role in geometry; geometric figures provide powerful ways to represent mathematical
situations and to express generalizations about space and spatial relationships. Students
use geometric thinking to understand mathematical concepts and the relationships
among them.

111.34(a)(3) - Geometric figures and their properties. Geometry consists of the study of
geometric figures of zero, one, two, and three dimensions and the relationships among
them. Students study properties and relationships having to do with size, shape, location,
direction, and orientation of these figures.

111.34(a)(4) - The relationship between geometry, other mathematics, and other
disciplines. Geometry can be used to model and represent many mathematical and realworld situations. Students perceive the connection between geometry and the real and
mathematical worlds and use geometric ideas, relationships, and properties to solve
problems.

111.34(a)(5) - Tools for geometric thinking. Techniques for working with spatial figures
and their properties are essential in understanding underlying relationships. Students use
a variety of representations (concrete, pictorial, numerical, symbolic, graphical, and
verbal), tools, and technology (including, but not limited to, calculators with graphing
capabilities, data collection devices, and computers) to solve meaningful problems by
representing and transforming figures and analyzing relationships.

111.34(b)(2)(A)(B)
…use constructions to explore attributes of geometric figures and to make conjectures
about geometric relationships;
…make conjectures about angles, lines, polygons, circles, and three-dimensional figures
and determine the validity of the conjectures, choosing from a variety of approaches such
as coordinate, transformational, or axiomatic.

111.34(b)(3)(A)(B)
…determine the validity of a conditional statement, its converse, inverse, and
contrapositive;
…construct and justify statements about geometric figures and their properties;

111.34(b)(6)(A)(B)(C)
…describe and draw the intersection of a given plane with various three-dimensional
geometric figures;
…use nets to represent and construct three-dimensional geometric figures; and
…use orthographic and isometric views of three-dimensional geometric figures to
represent and construct three-dimensional geometric figures and solve problems.

111.34(b)(7)(A)
…use one- and two-dimensional coordinate systems to represent points, lines, rays, line
segments, and figures;
Teacher Preparation:
You will need 2-3 copies of the six (6) grid paper for sketching on per student. It is
recommended that you make your own sketches to show the students. Have pencil, eraser, and
map pencils available for students who don’t have any.

Introduction
Introduction (LSI Quadrant I):
NOTE: The class discussion is meant to be Socratic in nature and not true/false, or this is the
only correct answer. Encourage your students to explain WHY they think the way they do! There
is NO wrong answer if they can explain the WHY!
SAY: Today you will be able to create your own thumbnail sketches.
ASK: Can anyone explain to the class what a thumbnail sketch is?
ANSWER: It’s a sketch that’s about the size of a thumb that shows what a product will look like
when completed.
SHOW: Go through the What is Sketching? PowerPoint presentation.
ASK: Can anyone give me examples of uses of thumbnail sketching other than in engineering
design?
ANSWER: Many, these are just a few. Plan a painting; plan scene in a movie; plan comic strip;
plan a poster layout; plan layout for a website….
SHOW: The example and see if they can guess what they represent.
SHOW: Them the 2D and 3D Computer Aided Drafting (CAD) examples.
ASK: Is this the ONLY way these could be planned out and drawn?
ANSWER: No, this is just how I would plan and do it. As long as you can get it drawn, it will be
correct.
SAY: You will now practice creating your own thumbnail sketches. For the first 1-2 days of this
lesson, you will practice drawing thumbnail sketches of your six (6) favorite childhood toys.
Coloring is optional. On the 3rd day, you will practice sketching out steps to draw the CAD
problem(s) given.

Days 1-2 practice drawing thumbnail sketches
of your six (6) favorite childhood toys. Coloring
is optional.
Day 3= practice sketching out steps to draw

plan scene in a movie;
plan comic strip; plan a
poster layout; plan

who need to refer to
examples.
Discuss if color helped
or not.

this the ONLY way
these could be
planned out and
drawn?”
Tell them this is just
how you would plan
and do it. As long as
you can get it drawn
yours is correct.
VI. You will now practice creating your own
thumbnail sketches.
Go around and help
kids who need it. Allow
2 days to sketch the 6
toys. Allow them to
use color if they want
to. It helps some
students to better
visualize the process.
VII. 2D and/or 3D CAD problems
A. Thumbnail sketch the steps on how
you would draw the problems
B. Draw the problems on computer
i. The Sling
ii. The Adjustable Stop
(Slides 33-35)
When students begin
the technical drawings
in CAD or Parametric
Modeling software like
Inventor or Solidworks,
require that they
thumbnail sketch out
the steps on how they
would do the drawing
BEFORE they begin to
draw it in the
computer.

Application
Guided Practice (LSI Quadrant III):
The teacher provides feedback as students are sketching their 6 childhood toys; and should
show every student’s sketches and see if everyone can guess what they are.
Independent Practice (LSI Quadrant III):
Students will complete the 6 childhood toys sketches on the gridded paper provided; and will
sketch the 2D and/or 3D CAD problems.
Summary
Review (LSI Quadrants I and IV):
As the students show their sketches, the teacher will ask if everyone can guess what the toys
are from each sketch that is shown. Can you guess what the toys are from your classmate’s
sketches?
Evaluation
Informal Assessment (LSI Quadrant III):
Make sure each student has 6 sketches to show.
Formal Assessment (LSI Quadrant III, IV
1. The six (6) favorite childhood toys sketches should be graded as “daily” work
2. When you begin the technical drawings in CAD or Parametric Modeling software like
Inventor or Solidworks, require that they thumbnail sketch out the steps on how they
would do the drawing BEFORE they begin to draw it in the computer.
3. Sketching Quiz
Extension/Enrichment (LSI Quadrant IV):
Students who need a challenge can sketch the steps for drawing the CAD problems given.
