Unit 1 Lab 2: Gossip, Page 3

Paul please note: Brian and I have agreed to drop costuming from 1.1 entirely (cutting the first part of page 2 and starting with problem 3b) and just giving them the costumes in a starter project on page 1.1.1. Then we'd teach adding costumes here (as shown below) before they write code to let the user change the costume in 2.1.5. Thoughts? --MF, 4/17/19

Open your U1L2-Gossip project. Edit these three reporter blocks to change the phrases that the program uses. (See the instructions in the box below.) Be creative and funny but thoughtful.
How to Edit a Block
1. Find the block in the scripting area or the colored palettes on the left.
2. Control-click (or right-click) on the block and choose "edit..."
3. Make changes to the block's internal code. (Instructions are already inside these blocks.)
4. Click OK when you're satisfied. (Or click "Cancel" if you don't want to make changes.)

Why do these blocks use report ()

? Why not just use say ()

The report and say blocks mean very different things. Report tells something to the computer, and that value can be used as input to another block, such as the join block inside gossip. Say just shows a value to the user in a speech bubble.

: Lists, Strings, and Concatenation

AAP-1.C.1 first sentence

A list is an ordered set of items. You've seen this example:

AAP-2.D.1, AAP-2.D.2

The items of this list are strings. A string is a sequence of characters (letters, digits, punctuation, etc.). A substring is just a piece of some existing string. For example, "Hanna," "anna", and "nnah" are each substrings of the string "Hannah." (The empty string as well as the original string are both also substrings.)
To concatenate strings means to make a bigger string by connecting two or more smaller strings. In Snap!, the block lets you concatenate strings.

This process of testing, finding problems, and fixing them is called debugging.

Make sure your program works. Test each block as well as the program as a whole. If something doesn't work, don't go on without fixing it.

AAP-2.D
Which of the following sentences could be reported by gossip?

For reference:

Señora and Ms. C helped.

It's true that there are two people (two "who"s) and one action (one "does what"), but they aren't in the right order. Also, the word "and" isn't anywhere in the program.

Señora ran away from my cat.

Correct! This follows the pattern: "who," "does what," "who."

Hannah listened to Hannah.

Correct! This follows the pattern: "who," "does what," "who."

Jake helped.

This sentence is missing the second "who."
Change the costumes to anything you like.
This currently duplicates some content on 1.1.2. We need to decide where costumes really belong. --MF, 4/17/19
Adding a Costume
1. In the sprite corral, select the sprite you want to give costumes to.
2. Choose "Costumes..." from the File () menu.
3. Choose a costume.
4. Click "Import."
5. Click "Cancel" to close the dialog box.
You can use a photograph or picture from the Internet by dragging the image onto the Snap! window.
Fix any issues with your costumes.
Adjusting a Costume
- You can change the size of your sprite using .
- You can change the position of your sprite using .
- You can change the direction your sprite is facing:
