2 Math and Science Activities in the Context of Baseball from the Event-Based Science Institute Teacher Version - Mathematics The secret to real learning learning that lasts is total engagement. When students are fully engaged in their work working in a real-world context, using vocabulary, skills, and concepts familiar to experts in the field learning happens naturally. When students are truly absorbed in meaningful work, memorization, drill and practice, and worksheets become unnecessary. The trick is not just to engage students in the first place, that is the easy part. The trick is to keep students engaged. The activities in this module are designed for use in middle school science and mathematics classrooms. They use baseball as their real-world context. The stories that you find in the Background section of each activity are true. They tell about real things that happen to real baseball and softball players. From the context of the story flows a challenging task that requires students to design and conduct an experiment or use a mathematics concept. This strategy is called Total Engagement Learning. Placing a learning activity in the context of something real gives students an authentic reason to learn. An authentic activity works too. It engage students for three reasons: CONTEXT A real-world context makes learning meaningful. PURPOSE An authentic activity gives students a reason to learn and use concepts and skills. DIFFERENTIATION Authentic activities demonstrate how people with different skills, interests and jobs can all use and apply the things we are learning in school. In the classroom this means role playing, and role playing means natural differentiation. Each activity comes in an online Student Version ( ce/baseball/ebs.baseballactivities.html) and a Teacher Version. Make a copy of the Student Version for each student to use. You may want to make just enough copies for one class and place them in sheet protectors to preserve them. The Teacher Version provides instructions on conducting the activity as well as references to the National Standards covered by the activity. Activities are also accompanied by readings. These readings come in two forms: Fundamentals - a brief discussion of the concepts (science or mathematics) dealt with in the activity. The Teachers Version will tell you how many copies you will need to make. Skills - a brief discussion of techniques and skills needed to conduct the experiment. The Teachers Version will tell you how many copies you will need to make. Some activities are also provided with resources. Resources are charts and tables that contain additional information for students to use as they complete the activities. The Teachers Version will tell you how many copies you will need to make. In a few cases, forms accompany the activities. If an activity has a form, you must print a copy of it for each student.

4 Base Running Teacher Version Objective Students will use measuring instruments to mark a specific distance, to clock running times for that distance, then use proportional reasoning to predict running times over a longer distance. National Council of Teachers of Mathematics Standards A whistle might also be helpful if more than 1 student is running at the same time. A whistle will also help you get the attention of everyone. While two students are measuring distance, have the player manager lead the rest in stretching and warming up. All Major League athletes warm up and stretch before every game. This warm up should not be optional. Any child refusing may be given the option of researching the benefits of stretching before strenuous activity! Understand numbers, ways of representing numbers, relationships among numbers, and number systems. Understand and use ratios and proportions to represent quantitative relationships. Compute fluently and make reasonable estimates. Develop, analyze, and explain methods for solving problems involving proportions, such as scaling and finding equivalent ratios. Description Preparation Obtain cones or other fieldmarking devices. If your school has access to a Babe Ruth League Field or Little League Fields ask permission to use the field and maybe even ask to borrow some of their bases. If someone asks, "Why don't we just run 90 feet instead of estimating our times over 90 feet?" Tell them that the 60-foot distance is more proportioned to the size of a middle school student. A student who is running at full speed for 90 feet will most likely tire and slow down during the last third of the longer distance. Work with your class to create a data table. Then Things that may go wrong and what you can do: have each student prepare a data table before going outside. It could rain schedule to use the gym if needed Gather all of the materials that are listed below. You go outside and forget a crucial If you do not have access to stop watches, a piece of material (i.e. stop watch) digital watch or a watch with a second hand can assign kids duties and responsibilities work. (i.e. equipment manager) so you, the teacher, do not have to remember everything. A checklist will help. Class Organization Organize students in small teams. If you have time, let your students decide how many people should be on each team and what job each student should have. Jobs can include timer (I student), recorder (1 student), distance measurers (2 students), referee (1 student to call starts), equipment manager(s) (1 or 2 students), player manager (1 student who makes sure that runners are in order and ready to go). Materials For each team 1 stop watch 1 measuring device (measuring wheel, tape measure, yard sticks, rulers, etc.) 1 clipboard 1 data table To help your students know when it is their time to run, names should be listed in order on the data table. To avoid arguments, jobs and responsibilities should also be listed. For individuals pencils sport shoes or baseball cleats Copyright Event-Based Science Institute 4

6 Baseball Cards Teacher Version Objective(s) Students will use data from a simulated baseball game to compute batting averages and calculate proportions. National Council of Teachers of Mathematics Standards Work flexibly with fractions, decimals, and percents to solve problems. Understand numbers, ways of representing numbers, relationships among numbers, and number systems. Understand and use ratios and proportions to represent quantitative relationships. Description This activity is designed to provide your students with practice with decimal fractions in the context of a simulated baseball game. Step 1: After reading the Background section, discuss with your class how it is possible for one player can have a better batting average than another player who has more base hits. As an example, you can compare Barry Bonds and Manny Ramirez (Resource Batting-Average Leaders). Ask your students to divide hits by at bats (AB) for Bonds and Ramirez. When working with a partner, each student continues to spin until there are three outs and then the other student spins. Students take turns spinning the spinner and recording the results in a chart until nine innings have been completed. In this simulated game, there is no way to track the score. The purpose is to establish a batting average for each student. Once students have completed 9 innings, each should complete the Game Statistics chart with their personal data from the game. Step 4: Students should use their data from the simulated game to estimate how many hits they would get if they were at bat as many times as their favorite player was in the regular 2002 season. To do this, have students set up a proportion like this: student data favorite-player data hits = x at bats at bats Step 5: Create a baseball card: Give your students some sample baseball cards. Have them discuss the kinds of information that appears on every card. Tell them that they are about to make their own baseball card. You will need to explain to your students that an official at bat is a turn at bat in which a player either makes an out or a base hit, or reaches base on an error or a force out. Base on balls, hit by pitch, sacrifice hits, or catcher's interference do not count as an official at bat. (For other baseball definitions, give your students copies of Fundamentals - Baseball Terms.) For the purpose of the simulated game in this activity, an official at bat is a turn at bat in which a player makes an out or a base hit. A walk does not count as an official at bat. Step 2: Give your students a copy of the 2003 Batting Statistics (Student Version). Together with your class, calculate the first batting average as a decimal fraction rounded to the thousandths place value. Let students work in pairs to find the missing batting average for each remaining player. Step 3: Playing the game: Have your students simulate a baseball game using a spinner. They can work with a partner, to play a simulated game. Distribute materials for the rough draft of the back of a baseball card. Have students fill in their personal data as if they were their favorite Major League player (using their own average, the at bats from the Major League player, and the hits they would have had if they batted as many times as their favorite player). After your students have finished the rough draft and you have approved it, give them the final copy to complete in ink. They can either draw their own picture on the front of the card or you can use a digital camera to produce a real picture for the front of the card. Copyright Event-Based Science Institute 6

Extending the Activity More advanced students can create spinners for their favorite players by creating circle graphs. The graph should be broken up into these categories: outs, hits, and walks. First, find the total plate appearances (PA) by finding the sum of walks and at bats. Next, find the percentages for the circle graph using these formulas: Walks= Walks/PA Hits= Hits/PA Outs= AB-Hits/PA Copyright Event-Based Science Institute 7

8 Designing Replica Ballparks Teacher Version Objective(s) Students will measure angles using a protractor and use proportional relationships to create scale drawings. National Council of Teachers of Mathematics Standards Apply appropriate techniques, tools, and formulas to determine measurements. Apply transformations and use symmetry to analyze mathematical situations Description This activity is designed to provide students with practice in preparing scale drawings. Students must have an understanding of proportional relationships in order to be successful with this activity. create a scale drawing that includes the outfield fence, the pitcher s mound, and the base paths. Students will create proportions by using values in Table 1-1 Major League vs. Babe Ruth League. It is recommended that you set up and solve one proportion problem to model the procedures for your students. Upon completion of the scale drawing, students must create a worksheet that features their computations. Also, the chart comparing MLB fields with Babe Ruth League fields provides measurements for different distances and they are not all in the same proportion. Therefore, instruct students to base their calculations of the distance to the outfield fence on the ratio of base distances. In the second part of their proposal, students provide the justification for their scale drawing. Students must explain each computation in order to prove to the Board of Trustees that their proposal is mathematically sound. The final part of the proposal is a written rationale of student s selection of their particular ballpark. Students are encouraged to include some interesting facts about the ballpark, share any personal experiences about the ballpark, and explain why other children would enjoy playing on a replica field of that ballpark. This section is intentionally placed as the third component. It is of primary interest that students complete the mathematical components of the activity before investigating their ballpark. Materials It is recommended that students work in pairs to promote mathematics communication and to ensure a quality product. Students will work cooperatively to create a proposal for the construction of a Babe Ruth League replica baseball field. You may want to explain that a replica baseball field is a scaled down version of its Major League counterpart. Begin the activity by asking, If you could play on any Major League baseball field, which would it be? The finished product for this activity is a threepart proposal. Students will use the dimensions of the Major League baseball field that they select and Babe Ruth League base distances to For each team Major League Ballpark Information Sheet Table 1-1 Major League vs. Babe Ruth League Fundamentals - Terms and Definitions Skills -Scale Drawings Graph paper Ruler Protractor Scoring Rubric See the Babe Ruth League Ballpark Information Sheet Answer Key for accurate Babe Ruth League measurements for each Major League Ballpark.

Several historical and/or personal facts about the ballpark are present in the rationale for selecting the stadium. 3 Points Most measurements and labels on the scale drawing are correct according to the selected scale. Explanations of most calculations are complete and accurate. A few historical and/or personal facts about the ballpark are present in the rationale for selecting the stadium. 2 Points Many measurements and labels on the scale drawing are incorrect according to the selected scale. Explanations are incomplete, inaccurate, or not presented at all. A single historical and/or personal fact about the ballpark is present in the rationale for selecting the stadium. No work completed. Extending the Activity 0 Point Junior Groundskeeper: Students determine how much it will cost to maintain their Babe Ruth League field. Students can calculate the cost of seeding the grassy areas and providing dirt for the infield areas by calculating the areas represented by each. Assistant Coach: One of the jobs of an assistant coach is to determine if their catcher throws hard enough to prevent opposing players from stealing bases. Students will assume the role of assistant coach and, in small teams, determine their throwing speed from home plate to second base. Students will have to use the Pythagorean Theorem to determine the distance between home plate and second base in order to complete speed calculation. 1 Point Copyright Event-Based Science Institute 9

10 Homerun Distance Teacher Version Objective Students will convert metric units to customary units in the context of baseball. National Council of Teachers of Mathematics Standards Understand numbers, ways of representing numbers, relationships among numbers, and number systems. Understand measurable attributes. Understand both metric and customary systems of measurements.. Convert from one unit to another within the same system. Description This is a two-day activity in which your students work together to measure how far they can hit a baseball and convert customary measurements to metric measurements. The first part of the activity requires a baseball field or other space outside. Bats and balls (tennis balls or baseballs) are needed during this activity. Although students are told to develop their own procedures, it is important to make sure that everyone conducts the experiment the same way. First let your students work in teams of two or three to brainstorm ideas for the procedures to use. Then discuss all of the ideas and decide on one set of procedures that is a composite of the best ideas from all of the teams. Be sure to offer suggestions of your own that insure the safety of your students. Also make sure that the final procedures include recording of all measurements in customary units (yards, feet, and inches). When your students come in from outside have them find a distance in the school (or their neighborhood) that is similar to the distance they personally hit the ball. Find another distance that is the same as the distance of the Barry Bonds homerun from the Background. These real-life measurements can include both long and very short comparisons from football field lengths, to candy bar lengths or anything in between. The next step in this activity is converting all measurements from customary to metric. Instruction and practice are provided in a number of forms: Fundamentals - Converting Measurements (Customary to Metric) Fundamentals - Converting Measurements (Metric to Customary) Skills - Practice Converting (Customary to Metric) Skills - Practice Converting (Metric to Customary) Worksheet - Home run Hitters Use one or all of these sheets to ensure that all students find success. Once all conversions have been successfully completed, have your students prepare for the evening sportscast. Print one Script-and-Shot Form for each student. Instruct your students to complete the form by making sure that they say and show everything that the producer wants. Make sure that everything fits a two-minute spot. The producer hopes that by using real-life measurements the audience will be better able to better visualize the distances.

13 In order for your students to understand how mathematics is used in everyday life, they need to be able to translate between words in English and expressions/equations in mathematics. Students who need additional support can read: Skills -Translating English Terms into Math Expressions Before you move to the last part of this activity, you may wish to help your students think about how they can meet the $10.00 requirement and at the same time meet other needs. One of those other needs might be setting a minimum requirement of buying at least one hot dog, one order of French fries, and one soda. (This exercise will allow students to start thinking about meeting the different requirements of their banquet their menu.) Next, students begin to examine how to create a menu. The menu will meet different needs and stay within the $400 budget. Students will work individually (allow 4 minutes), then together (allow 2 minutes), to help them to understand the project. You should circulate among your students to check on their understanding and progress. Once students understand the task, let them begin to work. Be sure that they include an explanation of the benefits of their menu.

The plan includes the expression that they used to determine the cost of the menu. All variables in the expression have been identified and all mathematical vocabulary has been used correctly. The plan also includes a discussion of the nutritional and other benefits of the menu chosen. 3 Points The student's plan to the local Babe Ruth League includes a menu that costs less than $400. The plan does not include the expression that they used to determine the cost of the menu. All variables in the expression have been identified and all mathematical vocabulary has been used correctly. The plan does not include a discussion of the nutritional and other benefits of the menu chosen. 2 Points The student's plan to the local Babe Ruth League only includes a menu. No work completed. Extending the Activity 1 Point Students who are capable of extending the activity can create a spreadsheet for their plan. Additional challenge can be offered by lowering the budget to $300 or $350. Different teams of students could be given different budgets. Students could then compare the challenges presented to them by having less money. Copyright Event-Based Science Institute 14
