Variables in Scratch

A variable like this one, can only hold one value at a time

• True

• False

Answer explanation

The statement is True because a variable can only store one value at a time. This is a fundamental characteristic of variables in programming.

A Variable can hold a value that can be:

• Names.

• Numbers

• a name.

• a number

Answer explanation

A variable can hold different types of values. The correct choices 'a name' and 'a number' represent the types of data a variable can store, while 'Names' and 'Numbers' are not specific enough to be considered valid options.

Variables can be used for:

• Keeping score

• Counting

• Controlling the flow of the program

• Starting a program

Answer explanation

Variables are essential for keeping score and counting, as they store values that can change during program execution. However, they do not directly control the flow of a program or start it.

What does this block mean?

• number of days = 5

• increase number of days by 5

• make the variable 'number of of days' hold a value of 5

• Add 5 to whatever value number of days was holding before.

Answer explanation

The block indicates to add 5 to the current value of 'number of days', which aligns with the choices 'Add 5 to whatever value number of days was holding before' and 'increase number of days by 5'.

If this script is given to a sprite, what will the sprite say?

• 5

• 6

• 30

What does this block mean?

• number of days = 12

• increase number of days by 12

• make the variable 'number of days' hold a value of 12

• Add 12 to whatever value number of days was holding before.

Answer explanation

The block assigns the value 12 to the variable 'number of days', meaning it directly sets 'number of days' to 12. This matches the correct choices, as it indicates the variable now holds that specific value.

If this script is given to a sprite, what will the sprite say?

If this script is given to a sprite, what will the sprite say?

• 3

• 9

• 5

If this script is given to a sprite, what will the sprite say?

• 7

• 9

• 5
