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 activity (Gaming Story).
(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 signed into Scratch and told a gaming story.”

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

In this activity, you're going to create a racetrack game in Scratch. This game will teach you how to code events and motions. Events are a really important computer science and gaming concept. In most games, you use button presses on a controller or keyboard to move a character. These button presses are all programmed using events. Events are a computer's way of handling an action, like a button press.

8. Preview the racing game.
(Show script)

In this activity, you are going to learn how to program arrow key events in a racing game. This is a two-player game in which each player gets to drive or move a sprite around the screen. Once you're done coding the project, you'll be able to play it with a neighbor.

  1. Pick up your passport.
  2. Choose a computer.
  3. Log in to your computer.
  4. Turn off your monitor.
Transition to Computer Time (2 minutes)
Directions Student Instructions
  1. Introduce computer time.
    (Show script)

    [show agenda] Now, we're going to move into the computer time.

  2. Remind members to use a sticky note if they have a question. [optional]  
    (Show script)

    If you have a question during this time, ask your neighbors for help. If they can’t help you, put a sticky note on your monitor and, I will come help you.

  3. Remind members that at the end of this activity you will pick a few projects to share next club.
    (Show script)

    Remember that at the end of this activity we will pick a few people’s projects to show at the beginning of next club.

  4. Have members turn on monitors and navigate to CS First website.
    (Show script)

    Please turn on your monitors, go to the CS First website, and start watching the first video.

  5. If there are new club members, provide them with your club code and ask them to go to cs-first.com/go to get sign-in information.
    (Show script)

    If today is your first time in this club, please begin by going to cs-first.com/go. Click "Enter Club Code," then follow the directions to get a sign-in and password.

  1. Go to cs-first.com.
  2. Sign in with the username and password from your club pass.
  3. Start watching the first video.
  4. If it's your first day, welcome! Go to www.cs-first.com/go and click "Enter Club Code" to get started. Ask your Guru for your club's code.
Watch Video 1 and Create (8 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.
  1. Open the starter project.
  2. Remix the project.
  3. Sign in to Scratch.
Watch Video 2 and Create (15 minutes)
Directions Student Instructions
  • Members are only using "event" blocks (dark gold) and "motion" blocks (blue). Look for members who have many different color blocks on their screen, and redirect them towards the "event" and "motion" blocks to complete this step. It's okay for club members to experiment and try different blocks, but filling the scripting area with many unrelated blocks may signal that a member is confused.
    (Show script)

    "How are you doing? [wait] How are you going to get the up arrow key to move this sprite forward? Have you considered..."

  • Members who are exploring the costumes or sounds tab may not understand the coding aspect of this activity. Remind them of the task, and try to answer any questions they have.
  • If club members want to move the sprite backwards, instruct them to try using a "move" block with a negative number.
Check to ensure that members have signed in to Scratch by looking at the top right corner of their Scratch project editor. If you see their username, they are signed in. If you see a "Sign In" link, that member still needs to sign in. Members who haven't signed in will not be able to save their work.
(Show script)

I see that you haven't signed in. Please click sign in, and enter your sign-in information from your passport so that you can save your project.

  1. Create an event for the three arrow presses.
  2. Add a "move" block to each arrow-press event.
Watch Video 3 and Create (15 minutes)
Directions Student Instructions
In the previous step, members were asked to code all three arrows. Some members may have difficulty matching the appropriate movements and events. If you see members who are frustrated by their sprite's movement, ask questions in an attempt to guide them.
(Show script)

Is that sprite moving the way you want it to? How would you like it to move?

  1. Add a "repeat until" block to each event to make the sprite move smoothly around the track.
Choose Add-Ons and Create (0 minutes)
Directions Student Instructions
During this time, members customize their projects by trying some add-ons. Add-ons allow members to explore programming concepts and features as they follow the guidance and instruction in the videos.
  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.

  2. Help members navigate the add-ons menu.
    (Show script)

    "When you click "watch," the add-on will open. To go back to the add-on selection screen, click on the X at the top of the video."

  3. If you notice that members have not saved or shared their projects (You will see a "See project page" button in the top right corner of the project editor on projects members have shared.), encourage them to do so before they continue working on add-ons.
    (Show script)

    I see that you're working on the add-ons. Be sure to save your project, and click "Share" to make it available to the Scratch community.

  1. Choose an Add-On, and click the "Watch" button to learn how to build it.
  2. After you finish, come back to the Add-Ons Screen and try another Add-On!
