JS Project to Teach kids alphabet

the prof. ask us to make aproject to tech alphabet and i doesnot know how to do it
can some one help with it
this is the description of the project :

In this project, you are required to implement a simple web application that allows kids in
schools to learn the basic English Alphabet. The basic idea is that, the user will choose
the number of letters he wants to learn, and when clicking on each letter, another page is
opened showing an image of something that begins with that letter. In addition, some user
interaction events are collected and stored in the localStorage object of the browser to be
used in subsequent versions of the project.
The application should look something like the following:

• It has an index.html page contains a number input and a button. The user chose
how many letters (from 1 up to 26) he wants to learn, then he presses OK.
A randomly chosen letters should be selected. For example, if the user wants to
learn 3 letters, he uses the number input field and chose 3, then presses OK and
after that he will get 3 randomly chosen letters from the English alphabet.

• The next step is for the user to click on one of the letters and then an Image is
displayed showing something that begins with that letter. Images are stored in a
folder for created for each letter (You should download some images from the
internet to use them in the project).
