Grade 5 CT: Timing is Everything!

Grade 5Computational Thinker Timing is Everything!

Overview

Today I will learn that timing in dialogue and movement is important when coding. I will use different command blocks to create algorithms to tell a joke in the right sequence and with the right timing.

Motivation

STEP 1.

Directions: Let's start by reviewing the Broadcast Coding Block and how it can be used to create dialogue using the Understanding Broadcasting Links to an external site. - Google Slides.

STEP 2.

Directions: Now let's take a look at this command in today's project. Follow along with your teacher as they demonstrate the Knock Knock Joke example below. As you view this coded program, think about:

Why is timing important?
What does the code include?

Let's Look Inside The Code

Follow along with your teacher to take a look inside the code of the Knock Knock Joke. Can you see how different command blocks are being used in the code?

What do you notice about the code for the sprites?
What blocks are used to make the sprites talk?
What blocks are used when the sprites are not talking?

Why is the broadcast command used instead of the wait command?
What steps do you need to follow to edit the program?

STEP 4.

Directions: Today we are going to use the skills that we have learned from the Broadcast Messaging Tutorial above to update a Knock Knock Joke code using an existing template. Select the Directions tab and follow along with your teacher to get started. Select the Video Tutorial tab if you need additional help.

STEP 5.

Directions: Using the Timing is Everything HCPSS project in Scratch for CS First, Edit the code for the sprites Abby & Avery to use broadcast commands to tell the knock knock joke instead of the wait commands.

Quick Check

What command will make it easy to get the timing right in a coded story?

The broadcast command. It will send a message to the next sprite that it is time to do or say something when it is the right time in the story.: Correct!
The wait command. I tell the sprite how long to wait before doing or saying the next thing.: The wait command will work but you have to guess at how long the sprite needs to wait before doing the next thing. If you change an action along the way, you will also need to go back and change all your wait block times.
