Error correction & sentence transformation

Error correction that marks itself

Students tap the wrong word and write it correctly, or rewrite a sentence with the word you give them. The worksheet marks it, accepts the alternatives you allow, and tells them how they did.

How it works

  1. 1

    Create the exercise

    From a PDF you already use, or type your own sentences in the editor.

  2. 2

    Set what counts as right

    Add accepted alternatives, allow small typos, and decide how strict accents and punctuation are.

  3. 3

    Assign it

    Students do it on their phone or computer. You see every answer and every mark.

Why teachers use it

  • Hard to find elsewhere

    Most error correction sheets are printables you mark by hand. Here they are interactive and marked for you.

  • More than one right answer

    Transformations often have several correct versions. List them once and every one is accepted.

  • Practice with a second try

    In Practice mode students can try again for half credit, so a mistake becomes a lesson.

Questions

Can students write the whole sentence again?

In sentence transformation, yes: they write the whole new sentence, and it is compared with your key and the alternatives you allow. In error correction they tap the wrong word and write only the fix.

What if a student makes a small typo?

You decide: typo tolerance can be on or off, per question.

Does it work for Spanish and other languages?

Yes. Accents and Spanish punctuation (¿ ¡) can be strict or lenient, as you choose.

Is it free?

There is a free plan for teachers with up to three classes.
