Where DeckOwl fits in a Scratch math quiz

Most people who search for how to make a math quiz in Scratch already know the basic blocks; the harder part is writing questions with correct answers. DeckOwl helps with that part.

Use one list for questions and a matching list for answers.
Pick a random position with pick random so questions do not always come in the same order.
Add 1 to a score variable only when the typed answer matches the stored answer.
Show the final score with a say block or a variable monitor when the quiz ends.

Example math questions for a Scratch quiz

Which Scratch block gives a random whole number, such as a question number from 1 to 10?The pick random block from Operators returns a different number each time the script runs, so you can choose a question at random.

What does the ask and wait block do in a Scratch quiz?It shows a text box, pauses the script until the player types and presses enter, and stores the reply in the answer block.

How do you check whether a typed answer equals the sum of two numbers a and b?Use an if block with the equals operator to compare the answer with a plus b, because the if block runs its contents only when the comparison is true.

How do you add one point to a score each time a quiz answer is correct?Use the change score by 1 block inside the correct-answer branch, since it adds to the existing value instead of resetting it.

How can a counter step through a list of quiz questions in order?Use the item (counter) of questions reporter, then add 1 to the counter after each question, because the item reporter returns the list entry at that position.

Questions from your notes

Upload a PDF, slides, DOCX or typed notes and get multiple-choice, true/false or short answer questions with explanations.

Test before you build

The free plan includes 3 generations per month and study in the browser, so you can check a question set before adding it to Scratch.

Exports on paid plans

Plus adds PDF and DOCX export for printing a question bank, and Pro adds QTI 2.1 and Moodle XML export.

How it works

Upload your math material

Add a PDF, DOCX, slides or a photo of a textbook page.

Generate the quiz

Pick multiple choice or true/false and copy the questions and answers you want to use.

Enter them in Scratch

Store questions in one list, answers in a matching list, then use a counter and if-then blocks to mark replies.

DeckOwl does not build Scratch projects or write Scratch code. It reads your math notes, textbook photos or slides and produces questions with the correct answer and a short explanation for each one.

Once you have a set, add the questions to a Scratch list, store the matching answers in a second list, then use a score variable and if-then blocks to check each reply.

Frequently asked questions

How many questions should a math quiz in Scratch include?

Five to ten questions is a practical size for a beginner Scratch project. That is enough to track a score without making the quiz tedious to play.

How do I check a math answer in Scratch?

Store the correct result in a variable, then use an if block with the equals operator to compare it with the answer reporter. Keep the number format the same for both values so the comparison behaves as expected.

Can DeckOwl build the Scratch project for me?

No. DeckOwl creates the math questions, answers and explanations from your own material, and you enter them into Scratch yourself.

Is exporting the quiz included in the free plan?

No. The free plan lets you study in the browser with 3 generations per month. PDF and DOCX export are on Plus at $99.90/year or $9.99/month, and QTI 2.1 and Moodle XML export are on Pro at $14.99/month.
