Grok for teachers

Teaching comes with a second job made of paperwork: plans, quizzes, rubrics, comments and messages home. Grok can draft much of it in minutes, and you keep the part only you can do, which is knowing your class. On grok.online the chat runs real Grok models for free, without sign-up, with 30 messages a day. Grok 4.20 is quick for text work; Grok 4.3 Thinking is better when a task has many moving parts. Here are seven uses, each with a prompt you can open and edit.

Prepare lessons and materials

Start with the material that eats your evenings.

Outline a lesson with timings

Give the objective, the length and what students already know. The thinking model is good at balancing activities against the clock and flagging where a plan is too ambitious.

Plan a [length]-minute lesson for [age or grade] on [topic]. The class already knows [prior knowledge]. Goal: by the end, students can [objective]. Give a timed outline with a hook, direct teaching, one paired activity, one independent task and an exit question. Note where weaker students may get stuck and one way to stretch the strongest.

Plan it with Grok 4.3 Thinking, then swap any activity that won't work in your room.

Write quiz questions with believable wrong answers

A multiple-choice item is only as good as its distractors. Ask for wrong options built on real misconceptions, so a student's choice tells you something.

Write [number] multiple-choice questions on [topic] for [grade]. Each question has four options, and every wrong option must reflect a specific misconception students commonly hold. After the questions, give an answer key that names the misconception behind each wrong option.

Generate the quiz. Check every answer key line yourself before you print.

Rewrite a text for two reading levels

Mixed classes need the same content at different levels. Paste the passage and keep the facts fixed while the language changes.

Rewrite the passage below in two versions for [grade] students: one for confident readers and one for students reading below grade level. Keep every fact and key term in both versions, explain the key terms in the simpler one, and list the vocabulary I should pre-teach: [paste passage]

Adapt your text. For shorter rewrites, the Paraphraser is enough.

Proofread a worksheet from a photo

Typos and ambiguous questions are easier to fix before thirty copies exist. Attach a photo of your draft worksheet and ask for a second pair of eyes.

I've attached a photo of a worksheet I made for [grade] on [topic]. Check it for spelling mistakes, wrong answers in any examples, and questions a student could reasonably read in two ways. List each problem with its question number and a suggested fix.

Open this prompt and attach the picture.

Assess and communicate

Marking and messages are where consistency and tone matter most.

Build a rubric students can understand

A rubric written in student language turns into a checklist they actually use. Ask for both versions at once.

Create a rubric for [assignment] in [subject] for [grade], with four criteria and four levels each. Write it twice: once in teacher language for marking, and once as "I can" statements a student could use to check their own work before handing it in.

Draft the rubric and adjust the criteria to your syllabus.

Find the misconceptions in a set of answers

Thirty short answers to the same question usually share three or four mistakes. Paste them without names and let the thinking model sort them, so tomorrow's lesson starts with the right fix.

Below are anonymous student answers to the question "[question]". Group them by the type of mistake or misunderstanding, say how many answers fall into each group, quote one typical example per group, and suggest a five-minute activity that would correct the most common one: [paste answers, one per line]

Sort them with Grok 4.3 Thinking.

Draft feedback comments from your notes

Your quick notes hold the judgement; the chat only turns them into kind, specific sentences. Use initials or nothing, never full names.

Turn my quick marking notes into short feedback comments for students. For each note, write two or three sentences that name one strength, one specific next step, and stay encouraging without empty praise. Notes: [paste notes, one per line, without names]

Write the comments, then read each one as the student would.

Write a calm message to a parent

Some messages home are hard to word. Grok can find a tone that is honest about the problem and still invites cooperation.

Help me write a short message to a parent about [situation]. I want to describe what happened factually, say what the school is doing, and suggest one thing we could do together. Keep it warm, clear and under 150 words, and avoid jargon or blame.

Draft the message. The Email Writer also handles formal school letters.

What to avoid

• Pasting student data. Names, grades tied to names and anything about health or family should stay out of any AI chat. Anonymise first.
• Publishing unchecked answers. Grok can make arithmetic slips and state outdated facts with full confidence. Work through every answer key yourself.
• Expecting current curriculum news. The chat has no internet access and a knowledge cut-off, so it may not know this year's exam changes.
• Letting the draft decide. A generated plan does not know your class. Treat it as raw material.
