when you decided to give 2 chocolates per student, chocolates needed = 2xN where N = Number of students.
Here '2' is a fixed number. '2' is a constant.
The letter 'N' can take any natural number value depending upon the number of students. 'N' is a variable.
A letter symbol which can take any value (of a certain set) is called a variable.
Quantities which have only one fixed value are called constants.
NOTE: In some cases literals are also used to denote constants. In such cases, the fact will be specifically mentioned.
For example, if a is a constant and x is a variable,
and have to deal with their product, then we write their product as ax and specifically mention that a is a constant and x is a variable.
Thus Algebra Symbols are both constants and Variables.

Recently, I have found a series of math curricula (Both Hard Copy and Digital Copy) developed by a Lady Teacher who taught everyone from Pre-K students to doctoral students and who is a Ph.D. in Mathematics Education.
This series is very different and advantageous over many of the traditional books available. These give students tools that other books do not. Other books just give practice. These teach students “tricks” and new ways to think.
These build a student’s new knowledge of concepts from their existing knowledge. These provide many pages of practice that gradually increases in difficulty and provide constant review.
These also provide teachers and parents with lessons on how to work with the child on the concepts.
The series is low to reasonably priced and include
There is an exclusive, Parent Information Page provides YOU with detailed reports of your child’s progress so you can monitor your child’s success and give them encouragement. These Reports include
Time spent using the program
Personalized remediation curriculum designed for your child
Details the areas of weakness where your child needs additional help
Provides the REASONS WHY your child missed a concept
List of modules accessed and amount of time spent in each module
Creates reports that can be printed and used to discuss issues with your child’s teachers
These reports are created and stored in a secure section of the program, available exclusively to you, the parent. The section is accessed by a password that YOU create and use. No unauthorized users can access this information.
