Introduction (5 minutes)
Directions Student Instructions
1. Greet members at the door as they arrive.
(Show script)

Hi [name]. Welcome back!

2. Ask members to pick up their passports, then sit at an empty computer and log in.
(Show script)

Everyone please pick up your passports and go to a computer. Sign in to CS First and Scratch. Once you have logged in, please turn off your monitors.

3. Once all members are seated and logging in to their computers, privately ask members who are sitting alone to move to a computer near other members.
(Show script)

Hi [name]. Today you’re going to need to be sitting near others to work on this project. Would you mind moving to a seat where you’ll be able to interact with other club members?

4. Use the silent signal to get member attention.
(Show script)

[Silent signal] I need everyone’s attention up here, please.

5. Have all members turn off monitors and remove headphones before starting. It is important that you enforce this rule or members will use the computers instead of interacting.
(Show script)

Everyone please turn off your monitors, so we can begin the introduction [wait for all members to turn off monitors].

6. Recap and review the last club: All-Star Passing Drill.
(Show script)

Will someone please raise their hand and remind me what we did in our last club session? Possible response: “Last club session we created a game in which the player had to pass accurately to receivers.”

7. Introduce the CS concept: variables.
(Show script)

In this activity, you will create a batting game that will calculate the player's batting average. The project will introduce the important computer science concept called variables. Variables are used to store data, which then can be used in calculations.

  1. Pick up your passport.
  2. Choose a computer.
  3. Log in to your computer.
  4. Turn off your monitor.

  1. Transition to showcase.
    (Show script)

    [Pointing at agenda] Before we begin programming this activity, let's view the member showcases selected at the end of last club. We will play each project, look at the code, and then applaud how awesome the project is. Let's look at the first project!

Watch Video 1 and Create (4 minutes)
Directions Student Instructions
Immediately after asking members to begin watching the first video:
  • Answer questions promptly so members can get started on the activity.
  • Go to a place in the room where you can see all of the monitors. Ensure that all members have begun to watch the first video. Look for members who are either not on the CS First site or who are watching the wrong video. Politely and privately redirect these members to the correct video.

  2. Remix the project.
  3. Sign in to Scratch.
Watch Video 2 and Create (7 minutes)
Directions Student Instructions
Look for club members who are designing (adding sprites, backdrops, etc.), and encourage them to experiment with code.
(Show script)

I see that you've spent a lot of designing this project. Do you have any plans for how you want to code it? Why don't you try experimenting with different blocks to see what you can make it do?

  1. Make the baseball move towards home plate using the “repeat until,” “move,” and “touching edge” blocks.
  2. Point the baseball in a random direction using “point in direction” and “random” blocks.
  3. Start the baseball in the same position before each pitch using a “go to x y” block.
  4. Pitch 5 times using “repeat" and “wait.”
  5. Make the baseball start moving when the green flag is clicked.

Directions Student Instructions
Remind members to pace themselves using the Club Agenda.
(Show script)

Everyone, remember to look up at the Club Agenda while you are working on this activity. Right now, you should be on Video [X]. Work hard to keep up with the agenda so you can finish your project. Don’t get caught up in any one step for too long, like designing your project, sprites, or backdrops.

Program the ball to sense if it is touching the bat after the batter swings using “if/then,” “touching color,” and “point in direction” blocks.

Directions Student Instructions
  • Variables can be a complicated concept. Encourage courage and persistence. To help club members find the bugs in their code, ask them questions about how the code changes the variable.
    • If the club member doesn't set the variable when the flag is clicked:
      (Show script)

      What value does the score start at? [Example response: 0] What value does it start at if you've played before?[Example response: Whatever the old score was] What block sets the value of the score? [Example response: "set <variable name> to"] Where would you put that block to make the score set at the beginning? [Example response: right after the "when flag clicked" block]

    • If the club member isn't changing the score:
      (Show script)

      What block will cause the score to change? [Example response: "change score by"] When do you want the score to change? [Example response: if the batter hits the ball"]? Where is this in the code? How much do you want the score to change by? [Example response: 1] 

  1. Add a variable named “hits” to your game.
  2. Keep track of the batter's hits using “change by.”
  3. Make the program wait 0.2 seconds before running the loop again.
  4. Reset the number of hits to 0 at the beginning of the game.
Watch Video 5 and Create (8 minutes)
Directions Student Instructions
  • Common problem: Make sure the message that is sent at the end of the game is the message that the coach receives.
  • Play the club members' games, especially if they ask you to. Be enthusiastic about each game!
  1. Calculate the batter’s batting average using a “division” block and the “hits” variable.
  2. Make the coach say the batting average.
  3. Let the coach know when to say the batting average using “broadcast” and “when I receive” blocks.
Choose Add-Ons and Create (0 minutes)
Directions Student Instructions

  1. Walk around, and encourage members to try the add-ons that interest them.  
    (Show script)

    It looks like you've finished the core videos. That's great! Move to the next page to learn about different ways to customize your project.
