Solve the equation
3(x + 2) = 15
3x = 13
x = 13/3
2. Try it yourself
2(x + 4) = 18

Less marking.
More teaching.
Turn a student’s mistake into their next breakthrough. Clear feedback, focused practice. You have the final say.
See how it works
3(x + 2) = 15. Multiply each term by 3. 3x + 6 = 15. x = 3.

Student work → your explanation → their next step
Small tools. A better feedback loop.
From a handwritten answer to a clear next step. Everything stays connected to the work in front of you.
See where it went wrong.
Keep the original work beside your feedback. Review the exact step that needs attention.
A closer look
Open the marked line in the student’s solution. It takes you straight to the explanation, with the original work still in view.
Make the explanation yours.
Adjust the language, add context and approve the feedback before a student sees it.
A closer look
Edit the explanation in your own words and select Approve. Student preview shows your version, so you can check the message before sharing.
Give them a way forward.
Follow the explanation with a focused exercise that tests the same idea.
A closer look
Open Practice and try the follow-up problem. An incorrect answer gives a hint; a correct answer confirms the next step.

Classroom examples
Follow a classroom scenario from the first mistake to the next independent attempt.
Mathematics / Middle school
A missed bracket. A clearer next attempt.
A learner knows how to solve an equation, but multiplies only the first term inside the brackets.
- 01
The challenge
The answer looks plausible, but the mistake starts one line earlier.
- 02
The teacher’s review
Keep the original solution open, explain the distributive step and approve the wording.
- 03
The student’s next step
Offer a similar equation so the learner can use the idea without copying the answer.
Worked exampleMathematics
Student work
3(x + 2) = 15
3x + 2 = 15
Teacher-reviewed explanation
3(x + 2) = 3x + 6
Multiply both terms inside the brackets by 3. Then subtract 6 and divide by 3: x = 3.
The next independent task
2(x + 4) = 18
The teacher begins with the learner’s written solution, rather than the final answer alone. Highlighting the second line makes the misconception specific: the outside multiplier must apply to every term.
The explanation can be shortened or rewritten before approval. In the student preview, the learner sees the reviewed explanation followed by 2(x + 4) = 18. The next attempt checks whether the idea transfers to a different equation.
A little help. Or a daily habit.
