Learn how to form the simple future tense with “will” and “going to”. We can also use “will” to talk about something in the future. “Will” is used instead of “to be + going + to”

Examples:
I will go to school tomorrow.
It will rain tomorrow.
She will call me later today.
We will talk about it next week.
We can often use “going to” and “will” in the same way, but “going to” is used for plans and predictions based on what we see now, and “will” for quick decisions, promises and offers.
Shall
You can say I shall (= I will) and we shall (= we will) to indicate plans, but this is formal and rare in US English, where “shall” is mainly used in offers and suggestions (Shall I…? Shall we…?).
- I shall clean the furniture tomorrow.
- We shall put away the toys.
Shall is used in questions to ask whether the listener(s) thinks the plans are a good idea. Shall is used with we or I, but not with you/they/he/she/it in questions.
- Shall we walk there? It’s a nice day.
- Shall I wash the outside of the windows next?
We use the Simple Future when we talk about something that is going to happen in the future.
To form the simple future with “going to“, we use (I, You, He/She/It, We/You/They), + “to be” + “going to” + a base verb (infinitive without “to”).

Examples:
I am going to go to school tomorrow.
It is going to rain tomorrow.
She is going to call me later today.
We are going to talk about it next week.
