Slide 1: What are Variables?
Variables are containers that hold values. They can be assigned different values during the execution of a program.

Slide 2: Types of Variables
There are different types of variables such as integers, floats, strings, and booleans. Each type has its own purpose and constraints.

Slide 3: What are Constants?
Constants are similar to variables but their values cannot be changed once defined. They are used when a value needs to remain constant throughout the program.

Slide 4: Types of Constants
Constants can have the same types as variables, such as integers, floats, strings, and booleans. The difference is that their values remain fixed.

Slide 5: Data Types
Data types define the type of data that can be stored and manipulated in a programming language. They determine the operations that can be performed on the data.

Write down 3 things you learned in this lesson.

Slide 12 - Question ouverte

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

Slide 13 - Question ouverte

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
Ask 1 question about something you haven't quite understood yet.

Slide 14 - Question ouverte

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
