Pick Random Block
The Pick random block, under the Operators category, picks a number between the
specified range randomly. For example, the pick random 20 to 50 block will randomly pick a number
from 20 to 50. This block is a reporter block.
The Operators blocks are used together with the condition blocks in the Control category to create
interactive projects.

Lab Activity 3 Experiential Learning
Let us create two variables Length and Breadth and accept
their values from the user. If the length and breadth are equal,
the sprite says so and draws a square, else it draws a rectangle
with the values input by the user.
1. Create a new project.
2. Add the Pen blocks.
3. In the Sprite Info pane, type 50 in the Size box to reduce
the size of the Cat sprite.
4. In the Variables blocks palette, create two variables –
Length and Breadth, and hide them.
5. In the Scripts area, create the stack of blocks as shown in
the image.
6. Click the Go button to execute the project.
The sample images for the project are given below.
