The baseball season is just warming up and the playoffs are around the corner. Why not bring “America’s Pastime” into the math classroom? The following problems challenge students to exercise some of the skills they learn in the middle school curriculum.

**Baseball Fantasy**

These two activities from PBS Mathline have pairs of students act as co-managers of a baseball team. Each pair receives a pack of baseball cards. They compute and analyze the key statistical data of the given players, make decisions on who they want to keep and who they want to trade, arrange their lineups, and play simulated games. Students use the key statistical data to construct individual player spinners, determine the line up, and play a simulated baseball game. The ultimate goal is to be the manager of the winning team of the Fantasy Baseball World Series.

**What Is Round, Hard and Sold for $3 Million?**

This activity challenges students to determine which is worth more today: Babe Ruth’s 1927 home-run record-breaking ball or Mark McGwire’s 70th home-run ball that sold in 1999 for $3 million. Compound interest is the main topic.

**Who’s On First Today?**

In this activity, students use hits and at-bat statistics to determine which of two baseball players has a better batting average.

**Fun with Baseball Stats**

In this lesson plan, students use baseball cards to convert statistics to decimals, fractions and percentages. Then, they use their statistics in playing a game. Activity sheets can be downloaded.
