English Grammar ToGo

A classic step-by-step grammar course, rebuilt as an interactive app.

English Grammar: Programmed turns a full programmed learning course into a clean, modern practice app. Work through units, lessons, and frames that guide you from simple sentences all the way to clauses, punctuation, and tricky verb forms—always one small step at a time.

The app uses a structured course with: • 12 themed units covering verbs, subjects, modifiers, pronouns, clauses, capitals, commas, apostrophes, and more. • Short lessons with a clear explanation at the top and focused practice frames below. • Multiple-choice drills for every concept, with one clear correct answer for each frame. • A consistent, distraction-free interface in light and dark modes.

What you’ll learn

Whether you’re a student, an adult brushing up, or a non-native speaker tightening your writing, English Grammar: Programmed gives you old-school drills with modern polish—one frame at a time. Unit 1 – The Verb and Its Subject • What makes a complete sentence (naming part + telling part). • Complete subject vs. complete predicate. • Simple subject and verb, and how to find them. • Action verbs vs. state-of-being (linking) verbs. • How nouns and pronouns work as subjects. • How pronouns replace nouns correctly. • Direct objects and indirect objects (e.g. “Dad gave me an orchid”). • Linking verbs (is, are, was, were, seems, became, looked…) and subject complements. • Compound subjects, compound verbs, and verbs made of more than one word (will be leaving, should have started).

Unit 2 – Patterns of the Simple Sentence • Subject–verb, subject–verb–object, and indirect object patterns. • How to spot direct objects (“What receives the action?”). • How to recognize real indirect objects vs. “to/for” phrases. • How linking verbs are completed by subject complements. • Compound parts: compound subjects, compound verbs, compound objects, and compound complements.

Unit 3 – The Work of Modifiers • Adjectives: what kind, which one, and how many. • Words that can be adjectives or pronouns (this, that, these, those). • Adverbs: how, when, where, how often, and how much. • Recognizing the difference between adjective and adverb forms (e.g. eager / eagerly). • Prepositions and prepositional phrases: position, direction, and time (on, under, to, from, until, through…).

Unit 4 – Building Better Sentences • How to recognize compound sentences with and, but, or. • When a sentence is not compound (shared subject or shared verb). • Adverb clauses: signals like because, if, when, while, until, so that and what they tell (when, where, how, why). • Adjective clauses: signals like who, whom, whose, which, that and how they modify nouns.

Unit 5 – Understanding the Sentence Unit • Sentence fragments: word groups that look like sentences but aren’t. • How to fix fragments by adding a missing subject or predicate. • Why dependent clauses like because the bridge collapsed are not sentences. • Run-on sentences and comma splices—and how to correct them with periods, commas + conjunctions, or better structure.

Unit 6 – Using Verbs Correctly • How irregular verbs really work: simple past vs. past-with-helper (began / begun, broke / broken, did / done…).

Unit 7 – Agreement of Subject and Verb

Unit 8 – Choosing the Right Modifier Unit 9 – Using Pronouns Correctly

Unit 11 – Learning to Use Commas

Unit 12 – Apostrophes and Quotation Marks
