A slice of the future: the action is already in progress
You met will be + -ing in Grammar 10. Here is the closer look. Pick a use, move the marker with a time expression, and watch the action stretch around that moment — you picture yourself already doing it, not starting or finishing it. (will be + -ing = una acción que ya estará en curso en un momento futuro.)
1 · Choose the use
2 · Move the marker
Future simple vs. future progressive
will + base names a complete action or a decision at a point (then); will be + -ing paints an action in progress around that point (during). The third box is the form you would use for right now. (Simple = en ese momento, completa; progresivo = durante, en curso.)

👩🏫 For the teacher — how this page maps to the manual
- Explore is Grammar 14 as a time slice: the three uses of the grammar box (in progress at a future time · future as a matter of course · polite enquiry about plans) drawn as a bar around a movable marker, with the manual’s time markers; the then/during card is the simple-vs-progressive table plus exercise A’s “right now”; the points-to-watch card is the exceptions box (stative verbs, polite vs. request, don’t drop be/-ing) with the negative/question forms and the Grammar 10 time-clause rule; the errors card is the pitfall list.
- Build is productive: students assemble a sentence by choosing the time expression and the verb form (exercises B and C), then transform plans into in-progress sentences and ask/answer a polite Will you be…? question (Task set 31 and the mixed review), with validation.
- Drill merges the quizzes into one graded engine (★ which use, simple or progressive, stative, polite · ★★ fix the error, complete, negative · ★★★ question form, in-progress rewrite, matter of course) with a score and streak.
- Works offline. Reading/writing only — no audio.
Build a sentence
Read the idea and the use it needs, then choose the time expression and the verb form. The machine builds the sentence — guess before you check.
Drill — one flow, three levels
★ which use? simple or progressive? · ★★ fix the error, complete, negative · ★★★ question form, in-progress rewrite, matter of course. Keep your streak alive. (Igual escalera que tu Cuaderno de tareas.)
