Writing fill in multiple blanks questions from your own material

Teachers building a canvas quiz fill in multiple blanks set usually already have the material: a chapter, lecture slides or their own notes. The hard part is finding the facts worth testing and phrasing them so each blank has one clear answer.

  • Pick one fact per sentence so each blank has a single correct answer.
  • Use two or three blanks at most so the question stays readable and gradeable.
  • List accepted spellings or synonyms for each blank before you publish the quiz.
  • Check the explanation for every generated item before using it with students.

Questions from your material

Upload a PDF, DOCX, PPTX, text file or a photo of a page. DeckOwl reads the text and builds questions from the facts in it.

Answers with explanations

Every generated question comes with its correct answer and a short explanation, so you can check the key before it goes into a quiz.

Export on paid plans

Plus exports to PDF, DOCX, Anki and CSV. Pro adds QTI 2.1 and Moodle XML export for learning management systems.

How it works

Upload your source

Add the chapter, lecture slides or notes that the quiz should cover.

Generate and pick facts

Review the generated questions and keep the key facts that suit a blank, such as names, dates or terms.

Write the blanks

Turn each fact into a sentence with one or more blanks, list the accepted answers, and export the set.

DeckOwl helps with the first part. It reads your file and produces multiple-choice, true/false and short answer questions with explanations, which show the facts a good blank should target. You then rewrite the chosen fact as a sentence with blanks, so the question matches your course wording.

Keep each question tied to a single idea and limit it to two or three blanks. Check that every blank has one defensible answer before you add it to a quiz.

Frequently asked questions

How do I write a fill in multiple blanks question with more than one answer?

Place each blank where a specific term belongs in the sentence, then record the correct answer for each blank in order. Keep every blank tied to one fact so a student cannot give a reasonable answer that is marked wrong.

How many blanks should one question have?

Two or three blanks per sentence is a practical range, since more blanks make the question harder to read and grade. Split longer passages into separate questions instead.

Does DeckOwl create fill in multiple blanks questions directly?

DeckOwl generates multiple-choice, true/false and short answer questions with explanations, not a fill-in-multiple-blanks question type. You can use the generated facts to write blank sentences yourself.

Which plan includes QTI export?

QTI 2.1 export is part of the Pro plan at $14.99 per month. Plus, at $39 per year or $7.99 per month, includes PDF, DOCX, Anki and CSV export, and students get 40% off with a school email.
