Aryan: Wow! I am feeling very happy to learn how to make a game. Thanks, dear! You have
explained me very interesting concepts about “scratch”.
Gowri: Yes dear, Bye Aryan! Have a good day.
Aryan: Ok bye Gowri. Have a nice day!
Let us revise what we have learnt:
Keys on keyboard and mouse clicks are used in Scratch script.
Variables are used to calculate the score in the project.
Values in variables can be changed in any time.
Reporter blocks are designed to fit in the input area of other blocks and gives
or returns the value of that variable or block.
Arithmetic operators blocks are “reporter” blocks, means gives or returns some
output.
Relational operators blocks are “boolean” blocks, which checks the values and
gives output in true or false.
Logical operators blocks give output in True or False.
