Instructional Strategies and Activities
Note to teacher:
This lesson plan applies students’ understanding of geometry and proportional
reasoning to real world problems. You could use only Day 2. Day 1 uses the subject of
baseball to provide practice using percents, decimals, proportional reasoning, and
scale. Day 3 includes an Open Response and a game and Day 4 an Extension Activity
and a Multiple Choice Assessment.
DAY ONE: INTRODUCTION TO PROPORTIONAL
REASONING AND REVIEW OF TRIANGLES
1. If you have one, show students a Louisville Slugger Bat, the official bat of major
league baseball. Babe Ruth, one of baseball’s greatest players, used a Louisville Slugger.
Ruth’s career batting average was .342, an amazing statistic when you consider that a
batting average of .300 is excellent for major league players. Batting averages are computed by dividing base hits by the number of times at bat and rounding off the answer
to three decimal places. So an average of .342 means that in 1000 at bats, Ruth averaged
342 base hits.
Go to www.baseballhalloffame.org/hofers/detail.jsp?playerId=121578 to see all of
Ruth’s statistics. Not only was he a great hitter, he was a great pitcher as well. And his
slugging average—a more complicated statistic that takes into account whether the
player hits a single, a double, a triple, or a homerun and thus measures the power of his
swing—is even more amazing.
2. Discuss batting averages as a way of evaluating skill and performance. Model and
solve together: If someone is at bat 50 times and gets 10 base hits, what would the
batting average be? Answer: .200
LOUISVILLE SLUGGER: Similar Triangles 2
If you think students need additional practice in the computation, give them a few
more problems to practice.
3. Ask questions that require the students to reason proportionally. For example,
you might ask, “Ten hits out of 50 at bats is the equivalent of how many hits out
of 25 at bats? 100 at bats?” You can use equivalent fractions to help the students
see the proportional relationships. Follow up with some comparison questions:
“Which batting average is better—10 out of 50 or 10 out of 40? 10 out of 50 or 5
out of 30?”
4. Distribute “Handout 1: Batting Practice.” This activity helps students prepare to
use calculators and practice proportional reasoning. After students complete the
problems, a good approach would be to encourage them to discuss their reasoning with partners and then share it with the whole class. Then other students can
respond with alternative ways of thinking about and solving the problems.
5. Introduce the video. Babe Ruth’s statistics demonstrate that he was a great baseball player—many argue the greatest that has ever played. Mathematics backs up
this argument.
One of the Louisville Slugger bats that Babe Ruth used in 1927, the year he set the
record for most homeruns, is on display at the Louisville Slugger Museum and
Factory in Louisville, Kentucky. Louisville Sluggers are created using math, science,
and engineering.
6. Watch the video. Call attention to the large model bat and glove at the end. Students will be using proportional reasoning to calculate model sizes. Students will
also watch the video again on Day 2.
7. Distribute “Handout 2: Sizing Up the Team.” In this activity, students practice
using proportional reasoning to determine the heights of different scale models.
Before you discuss the method outlined below for solving problem one, ask the students to think about the problem. Will the statue be taller or shorter than the bat?
How did Babe’s height compare to the height of the 34-inch bat? Can you come up
with a rough estimate for the height of the statue? Thinking about the problem in
concrete terms will help the students see the meaning behind their calculations.
Solve problem one as a demonstration. Solve problem two as guided practice. Students should solve problem three on their own.
TEACHING TIP:
The five-step method described here gives students a way to set up equivalent
ratios and introduces cross multiplication as a possible means of solving proportional reasoning problems. However, it’s good practice to encourage students to
think about the concepts and come up with their own solutions. Let students
know there’s no single correct approach to these problems.
Allowing students to puzzle over problems and discuss various solutions with
partners, small groups, and/or whole class will help them see the concepts that
underlie cross-multiplication and other methods of solving proportional problems. Unless students have a conceptual grasp of proportionality, many won’t
remember how to cross-multiply when they need to apply proportional reasoning in subsequent math and science classes or in everyday life.

NOTE TO TEACHER:
Before you get to step 4, ask students to propose ways of solving for “x.” These
might include finding the equivalent fraction or seeing that the value of a known
ratio (1:2 = 0.5, for example) will equal the value of the equivalent ratio in the
proportion (1:2 = x:50; 50 x 0.5 = 25; x = 25). You also might ask them to explain
why cross multiplication works as a way of solving these problems (1:2 = 25:50;
1 × 50 = 50; 2 × 25 = 50). They could work as pairs or small groups to come up
with an explanation and then share it with the rest of the class. Encourage students

DAY TWO: SIMILAR TRIANGLES
1. Distribute “Handout 4: Batter Up! Pay Attention” viewer’s guide for students to
complete while watching “Greetings from the Louisville Slugger Museum.” If students
watched the video during Session One, reviewing it with the viewer’s guide will add
variation as well as introduce today’s lesson.
2. Check answers to the viewer’s guide.
3. Allow students some time to come up with theories on how to measure the world’s
largest bat using shadows, a regular bat, and proportional reasoning.
4. Tell students that we use proportional reasoning to calculate and compare. Today
we will compare the dimensions of triangles using proportional reasoning. Use a
projector to show students the Similar Shadows interactive at www.scalecity.org.
LOUISVILLE SLUGGER: Similar Triangles 4
5. As you explore the interactive, ask students the following questions:
• What is similar about the objects?
• How would these bats and shadows form triangles? (Once they have offered
possible answers, click on the triangle button to view.)
• In what ways are these triangles alike? (The smaller triangle can be moved
to fit into the larger triangle. They both have right angles. The lower lefthand angles are the same size.)
• If two angles are the same, what do we know about the third angle?
• Why is the ratio of each bat’s height to its shadow the same?
6. As a class exercise, complete the questions in the interactive. Select a different object or time of day for additional
practice. This page offers ample exploration and computation practice. Additional practice at home or in a computer lab would be beneficial to students. (See sample e-mail message to parents below.) In addition to the interactive
computations, students also could determine the size of the third angle in the triangles at dawn, midmorning, and late
afternoon.
7. Discuss congruency and similarity through exploring the bat examples in the
interactive.
• Are these triangles congruent? (No, the sides are not the same.)
• Are their angles congruent? (Yes, the corresponding angles are congruent.)
• Define similarity.
• Discuss angle-angle as a means of proving triangles to be similar.
• How do these triangles meet the criteria for similar triangles?
8. If desired, use “Handout 3: Do You Remember Triangles?” as a review and check-up (if you didn’t use it on Day
One). This handout also could be homework. The students’ answers will inform you about their understanding of the
properties of triangles and whether they have the computation skills needed to work with similar triangles. You may
decide this review is not necessary based on your knowledge of student ability and knowledge.

Sample e-mail to parents
Dear Parents,
We are working on a study of proportional reasoning in math class using the following
web site: www.scalecity.org.
You may access this web site at home for additional practice and interaction with your
child. KET has designed this web site for exploration and practice of mathematical
concepts. The “Check Answer” button allows students to monitor their own understanding as they work the problems.

LOUISVILLE SLUGGER: Similar Triangles 5
DAY THREE: OPEN RESPONSE AND GAME
1. Students complete the Open Response.
2. As time allows, divide the class into two baseball teams for “Game Time.” Use
“Handout 7: Game Time Questions” to quiz the students. You may want to put the
questions up on the overhead one by one rather than distributing them to the teams.
If the teams have the questions ahead of time, it might give them unfair advantage.
Directions:
• For the “batter’s boxes,” place two seats at the front of the class beside whiteboards. Different students from each
team will go to the batter’s box to answer questions. Alternately, you could have two students from each team go
to the batter’s box so they could talk to each other about the problems. Draw two baseball diamonds, one for each
team, on the classroom whiteboard or blackboard, to mark what base students are on when they answer correctly
and to advance any players already on base to second, third, or home as appropriate. You might designate one or two
students as umpires to make sure this is done accurately.
• Teams could be “at bat” until they have three outs, just as in the real game. Practically speaking, however, it would
probably work better to have them alternate.
• Allow students one minute to answer each question using calculators or computation. After completing the
problem, the batter shows the team his or her answer and gets a thumbs-up or thumbs-down. At this point, the
batter may change the answer or stick with the original response. The team with the most runs wins the game.
• Regardless of who is batting, all students are expected to work each problem. Easy questions are singles. Difficult
questions are home runs. The teacher may choose the difficulty level for individual students. Since they are
working problems in front of the class, all the “batters” should have a good chance to make a “hit.” Students
could also choose which level question they want to answer.
DAY FOUR: EXTENSION ACTIVITY AND MULTIPLE
CHOICE ASSESSMENT
1. Choose one of the Extension Activities described on pages 7-8.
2. Complete the Multiple Choice Assessment (see pages 11-12).

Extension: Comparing Baseball Fields
For additional experience, students could compare baseball field dimensions using “Handout 8: Little League and
Major League Baseball Fields.” This handout could serve as regular class work, extra credit, or independent work.

This site includes information about the dimensions of high school, college, and professional baseball fields.
Extension: The 3-4-5 Rule
To make sure corners have perfectly square angles, carpenters often use the 3-4-5 rule. A triangle will have a perfect 90°
angle across from its hypotenuse if it is similar to a triangle with sides measuring 3, 4, and 5.
5
3
4
Explain the 3-4-5 rule, and have students test it with centimeter graph paper and rulers. What happens when you make
a triangle with legs of 6 and 8 cm? Of 9 and 12 cm?
Then divide students into teams and give them chalk, pencils, tape measures and/or rulers, and lengths of string and
ask “How can you use some of these tools and the 3-4-5 rule to determine if apparent right angles in our classroom
(door and window frames, desks, corners, whiteboards, bookshelves) are perfectly square?”
Students would need to decide an appropriate scale for their 3-4-5 triangles (i.e., inches for a bookshelf, feet for the
corner of the room, etc.). They could measure and use the chalk to mark three units down one side of the supposed
right angle and four units down the other and then measure the hypotenuse to see if it is five units.
Others might realize that if they knot the string into 12 evenly spaced sections using the ruler or measuring tape, it can
form a perfect 3-4-5 triangle. In either case, the groups should chart their findings, report back to the class, and compare their results with those of other students.
To extend this lesson further, students could research could research how string is used for measurement. The following web sites provide background information.

Activity for Students with Learning Disabilities
Using chalk to record shadows throughout the day is a good way to engage students
with cognitive disabilities in the phenomena and mathematics of shadows. This
could also be a nice family project. Students should be instructed to pick a sunny day
and have a partner draw their shadow at different times of day while they stand or sit
in the same location.
Primary Activity Using Chalk To Measure Shadows
WWWEDUCATIONWORLDCOMA?LESSONLPSHTML
For students with cognitive disabilities, the numbers in this lesson may interfere withunderstanding. Begin by discussing
shadows that are the same size as the object. Then discuss shadows that are twice the size.
TEACHING TIP:
All your students might benefit from seeing one or two of these simple proportions before they move on to the
decimals that are used in these lessons.
Increase the complexity to match student understanding. To make the lesson more engaging, use photographs of students and their shadows. For example, the student’s image could be cut out of copy of a photograph and compared to
the photographic image of his or her shadow to show that the shadow is twice student’s height.
This lesson also can offer practice in creating and reading charts. Students could chart the lengths of their own shadows
at various times of day. They also could make a chart listing other objects and the lengths of their shadows. More
advanced students might predict the length of the objects’ shadows and test their predictions by measuring the actual
shadows at different times of day.
Advanced Extension: Independent Research
Advanced students can explore the basic idea behind the Pythagorean theorem. Using actual squares in the pattern of
a2 + b2 = c2 and experimenting with different dimensions will add meaning to the computation.
Students could conduct an investigation of the Pythagorean Theorem by exploring the following questions:
• Who was Pythagoras?
• What is the Pythagorean Theorem?
• What does the Pythagorean Theorem have to do with right triangles?
• How could you visually represent the Pythagorean Theorem with squares?
• How does the Pythagorean Theorem show that it is impossible for the side opposite
the right angle to be the shortest side?
• How is the Pythagorean Theorem used today?
• How could you use the Pythagorean Theorem to calculate the length of a throw from
first to third base or from second to home? (Students may need prompting to see
that the baseball “diamond” is really a square.)
• What some other Pythagorean theorems involving triangles?

Science
A companion study on shadows relative to time of day and time of year fits nicely
with this lesson. Students could photograph and record data about their shadows at
various points in the day from the same location. Challenge students to measure
shadows of objects of unknown height and use their skills with similar triangles to
determine the heights.

An exploration of Egyptian pyramids and what is known of their construction would go very nicely with this lesson.
As a topic for enrichment or even extra credit in math, students could explore the following questions:
•What is known about the age and purpose of the pyramids?
•How have the pyramids endured over time?
•How are triangles involved in the construction of the pyramids of Ancient Egypt?
•How are right angles important in the construction of the pyramids?
•What is the story of how Thales measured the height of the pyramids?
