In this activity, we will build a simple addition calculator in PictoBlox. The program will ask the user to enter two numbers, add them together, and display the result using a sprite.
Setting Up
- Open PictoBlox and create a New File.
- Select Block Coding as the coding environment.
- Choose any sprite — we will use Tobi for this activity.
Creating the Variables
- Go to the Variables palette and click Make a Variable.
- Create a variable called Number1.
- Create another variable called Number2.
- Create a third variable called Result.
Building the Script
Now let's build the script. You will find the blocks in the mentioned palettes:
- When flag clicked — Events
- Ask (Enter the first number:) and wait — Sensing
- Set (Number1) to (answer) — Variables
- Ask (Enter the second number:) and wait — Sensing
- Set (Number2) to (answer) — Variables
- Set (Result) to (Number1 + Number2) — Variables & Operators
- Say (join (The answer is: ) (Result)) for (3) seconds — Looks & Operators
Running the Script
- Click the green flag to start the program.
- Enter the first number when prompted and press Enter.
- Enter the second number when prompted and press Enter.
- Watch Tobi display the sum of the two numbers in a speech bubble!
Challenge
Try extending the calculator to support all four operations — addition, subtraction, multiplication, and division. You could ask the user which operation they want to perform, then carry it out!
