Sentences

Building a sentence that makes sense

A sentence is the smallest unit that makes a complete point, and most early writing problems are about where one ends rather than about vocabulary.

The unit covers what a sentence is, who did what, capital letters, full stops and question marks, and joining sentences.

This unit breaks down into 20 short steps and 118 questions, starting at difficulty 1 and building to 2. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

Where this fits

Follows Words and Meanings.

Where people slip

Length does not make a sentence. A long string of clauses joined by and is not more complete than a short sentence, and a short sentence is not a fragment.

How the unit is structured

Sentences runs as 20 short steps that unlock in order. 15 are practice rounds and 5 are challenge rounds that pull together everything before them. Questions start at difficulty 1 and climb to 2 as you progress.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
