Building the logic behind a math quiz

Most first attempts at how to make a math quiz in MIT App Inventor get stuck on the same step: the questions are easy to type in, but the app also needs a way to pick one, check the answer and keep score.

Use a Label to show each question and set its Text property from a list.
Compare the user's answer with the correct answer using a math or logic comparison block inside an if-then block.
Pick the next question with a random integer block so the order changes each time.
Test each branch of the quiz, including a correct answer, a wrong answer and the final score, before you share the app.

Example math quiz questions for App Inventor

Which Math drawer block picks a random whole number for a quiz question?The random integer block, set with a from and to range, because it gives a new whole number each time it runs.

Which block checks whether a typed answer matches the correct answer?A comparison block inside an if-then block, because it returns true only when the two values are equal.

Why convert a TextBox value to a number before comparing it with a computed answer?Use a number conversion block, because a TextBox returns text and text is not treated as a number until it is converted.

Which component displays the question text on screen?A Label, set through its Text property, because a label shows text the user cannot edit.

Which event runs the scoring blocks after the Check button is pressed?The when Button.Click event, because App Inventor runs the blocks inside an event handler only when that event fires.

Generate the full set

Questions from your notes

Upload a PDF, slides or typed notes and DeckOwl drafts multiple-choice, true/false or short-answer questions you can paste into your app.

Answers with explanations

Each question comes with a correct answer and a short explanation, so your app can show feedback after a wrong choice.

Study mode in the browser

Test the questions yourself in DeckOwl before you build them into App Inventor, so the quiz content is right before the blocks go in.

How it works

Upload your math material

Add the chapter, worksheet or lecture slides you want the quiz to cover. Photos of pages also work.

Generate and review the questions

Choose the question types you need, then check each answer and explanation against your notes before you use it.

Build the quiz in App Inventor

Place a Label for the question, Buttons for the answers and a Label for the score, then use blocks to check each answer and update the total.

The layout is the simple part. Use a Label for the question text, a TextBox or Buttons for answers, and a block that compares the chosen answer with the correct one. Store the questions in a list so a random integer block can choose the next one, and keep the score in a variable that changes each time an answer is checked.

Frequently asked questions

How many questions should a math quiz in App Inventor have?

Start with five to ten questions so you can test the logic quickly. Add more once scoring and feedback work, and mix easy and harder items so you can see whether each branch runs correctly.

How do I check whether a student's answer is correct in App Inventor?

Compare the chosen answer with the stored correct answer using a comparison block inside an if-then block. If the TextBox value is text, convert it to a number first so the comparison works with math results.

Does DeckOwl build the App Inventor project for me?

No. DeckOwl generates the questions, answers and explanations from your notes, and you place the components and blocks in App Inventor yourself.

Can I export the quiz questions?

Exports are part of the Plus plan, which includes PDF, DOCX, Anki and CSV at $39/year or $7.99/month. The free plan includes three generations per month and studying in the browser, without exports.
