Maths in baseball: personal bests

Compare old and new results.

Quick answer

Maths in baseball helps us compare how players do over time. We can find out who is getting better by looking at their scores, runs, or hits and seeing if they are going up or down.

Learning outcome

By the end of this page, you will be able to compare old and new baseball results to find out if a player's personal best is improving or not. Success signs:
  • You can look at two sets of numbers and say which one is better
  • You can find the highest number in a list
  • You can explain if someone is getting better or worse at something
  • You can use a chart or table to show your results

Why this matters

Maths in baseball helps us understand how players are doing. When a player gets better at hitting the ball or running bases, we can see this in their numbers. This is useful for:
  • Tracking your own progress in sports
  • Choosing which players to watch or play with
  • Understanding how people improve at anything
  • Making predictions about future performance

How it works

To compare personal bests in baseball, we:
  1. Look at a player's scores from different times
  2. Find the highest score or best result
  3. Compare that best score with earlier scores
  4. Decide if the player is getting better or not

Examples you can see

Let's imagine a baseball player named Sam. Here are Sam's scores from the last 5 games:
Game Runs Scored
Game 1 2
Game 2 4
Game 3 1
Game 4 6
Game 5 3
Now let's find out Sam's personal best:
  • Game 1: 2 runs
  • Game 2: 4 runs
  • Game 3: 1 run
  • Game 4: 6 runs
  • Game 5: 3 runs
Sam's personal best is 6 runs from Game 4. We can also make a simple bar chart to show this:
  • Game 1: 2 bars
  • Game 2: 4 bars
  • Game 3: 1 bar
  • Game 4: 6 bars
  • Game 5: 3 bars
This shows that Sam's personal best is 6 runs, which happened in Game 4.

Try it as a mini adventure

Sam's Baseball Challenge You are Sam's coach and need to find out if Sam is getting better. Here's your mission: Step 1: Look at Sam's scores from the last 10 games:
  • Game 1: 2 runs
  • Game 2: 3 runs
  • Game 3: 1 run
  • Game 4: 5 runs
  • Game 5: 4 runs
  • Game 6: 6 runs
  • Game 7: 3 runs
  • Game 8: 7 runs
  • Game 9: 2 runs
  • Game 10: 8 runs
Step 2: Find Sam's personal best from these 10 games. Step 3: Which game had the highest score? Step 4: Has Sam improved over the 10 games? Explain your thinking. Step 5: Draw a bar chart showing all 10 games. Step 6: Write a sentence about how Sam's performance is changing.

Common mistakes

  • Mistake: Thinking that the last game's score is always the best. Why it happens: Children often think the most recent number must be the best one. Fix: Look at all the numbers and find the highest one, not just the last one.
  • Mistake: Comparing the wrong numbers. Why it happens: Children may mix up which numbers to compare. Fix: Make a list and look at each number carefully, or use a chart to help.
  • Mistake: Not knowing what "personal best" means. Why it happens: The term can be confusing for young learners. Fix: Explain that personal best is the highest score you've ever had.

Parent and carer guide

As a parent or carer, you can help by:
  • Playing a simple game where you both record scores over time
  • Using everyday situations to practice comparing numbers
  • Encouraging your child to explain their thinking when comparing scores
  • Using charts or drawings to help visualize the numbers
  • Noticing when your child compares their own performance with past results
What to say:
  • "Let's look at your scores from last week and this week"
  • "Which number is the biggest in this list?"
  • "How can we tell if you're getting better?"
  • "Can you draw a picture to show your best score?"
What not to worry about:
  • Children may not get the answer right away - that's normal
  • It's okay if they need to count or use fingers to compare
  • Focus on the process, not just the answer
