In English, we have 'I am going' + infinitive, for example, I am going to eat. This can describe an event in the near future. Then, we have the term "will" for talking about a future that is more distant and predictable. These two types of future tense also exist in French, but in Italian, there is only one. It is always "I will...", except the future tense is expressed through different verb endings as opposed to a a single word expression such as "will." It is just a case of learning these endings and then you'll be able to construct the future tense with ease!
Before I go into the details of conjugation - that is to say, matching the verb endings with the different pronouns (I, you, he, we, etc.) - I want to make you aware of a phrase that can be used to describe the immediate future. This is not a grammatical tense, but just a phrase that translates to "I am about to... ." The expression is 'sto per' + infinitive. For example, "sto per mangiare" - I am about to eat. This phrase can be useful for the sake of variety or possibly convenience if you go blank and can't remember the future tense.
(then I would go on to explain how to conjugate the future tense, and how there are different verb endings for different types of verbs. If it was a new grammatical tense, it might take a big part of the lesson because it is essential foundational content)
