Grammar practice with examples: how to explain a rule and create exercises with an answer key
The "Grammar practice" tool helps explain a grammatical rule and immediately create exercises with an answer key. In the web form there are two fields: "Your text or idea" and "Audience or experience level". You choose the output language, press Generate, and get one result in a separate panel. It can be copied or downloaded as a plain text TXT file. In this article we will explore how to get different variants from the same rule, compare them, and refine them for your tasks. Important: the tool does not save results automatically, does not compare versions, and does not publish materials. All examples in the article are fictional and provided for illustration.
Open tool: Grammar practice ↗What the tool does and how to formulate a request
The tool solves two related tasks: it explains the requested rule and creates exercises with an answer key. Input is text or an idea (up to 8000 characters) and an audience description (up to 1000 characters). For example, you can write: "Explain the difference between past simple and present perfect with examples" and specify the audience "adults, level A2". The output will be an explanation and a set of exercises with answers. This is not a chat: there is only one result, it cannot be asked to "continue" or "change" in the same session. To get another variant, you must change the input data and generate anew.
The more specific the request, the more useful the result. Instead of "explain tenses" it is better to specify the rule, context and desired volume. For example: "Explain the difference between past simple and present perfect for B1 level, provide 5 examples and create 8 exercises choosing the correct form". If you want exercises only on substitution or only on translation, state that too. The audience affects the complexity of vocabulary and the depth of explanation: for beginners it is better to avoid terminology, for advanced users the meta-language can be used.
Remember the limitations: the tool does not check your answers, does not keep statistics, and does not adapt automatically. It is not intended for uploading documents, text recognition or batch processing. The result may contain errors, so the answer key must be checked manually. If you are working with a class, do not rely solely on the generated key: verify it against a textbook or your own understanding of the rule.
Example request: input: "Explain the usage of articles a/an/the for level A2, provide 6 examples and create 10 exercises on inserting the article". audience: "adults, level A2, Russian-speaking".
How to change criteria to get different variants
The simplest way to get a different variant is to change the audience. The same rule can be explained for children, for adults at A1 level, for B2 students or for teachers. For children it is better to use short sentences and familiar situations, for teachers - to add methodological comments and typical errors. The audience formulation affects examples, vocabulary and the number of exercises.
A second way is to change the exercise format. You can ask for only multiple-choice options, only bracket expansion, only error correction or only translation from Russian to English. If needed, specify the number of exercises and the presence of an answer key. For example: "Create 12 exercises on bracket expansion and answer key". A third way is to change the volume of the explanation: brief (3-4 sentences) or detailed (with a table of cases). Fourth - add context: business English, conversational speech, academic writing.
Do not be afraid to combine criteria. For example, "explain the rule for B1 level, provide examples from business correspondence, create 8 exercises on error correction and answer key". The more parameters you set, the more predictable the result. But do not overload the request: if there are too many criteria, the model may miss something. Better to do several generations with different accents and then select the best fragments.
Variant 1: audience "children 10-12 years", exercises on multiple choice. Variant 2: audience "adults, level B1", exercises on translation. Variant 3: audience "teachers", added typical errors and methodological comments.
Comparing three variants on one rule
Consider a fictional example: the rule "Present Perfect vs Past Simple". Variant A generated for audience "schoolchildren, level A2". It contains a simple explanation: Past Simple - for a completed action with a time indicator, Present Perfect - for a result or experience without a time indicator. Exercises: 8 tasks choosing the correct form. Variant B - for "adults, level B1, business English". The explanation includes cases with just, already, yet, for, since. Exercises: 10 tasks on correcting errors in business letters. Variant C - for "teachers". Added typical errors of Russian-speaking students and recommendations for explaining the rule.
Comparing variants is convenient by three criteria: accuracy of explanation, correspondence to the audience and quality of exercises. Variant A may be too simple for adults, but perfect for children. Variant B contains more complex vocabulary and context, but may be overloaded for beginners. Variant C is useful for a teacher but not suitable for independent study. Choose a variant for a specific task, not "the best in general".
If none of the variants fully fits, you can manually combine fragments: take the explanation from variant B, exercises from variant A, and check the key yourself. The tool cannot merge results, so you need to copy the desired parts into a separate document. Such an approach saves time and allows you to keep the best from several generations.
Variant A (A2): "I lost my key yesterday. I have lost my key, so I can't open the door". Variant B (B1, business): "I have just sent the report. I sent the report yesterday". Variant C (teachers): typical error - "I have seen him yesterday" instead of "I saw him yesterday".
Selecting and refining the result
After generation you get one text result. It can be copied or downloaded as TXT. Then manual refinement begins. Check the answer key: sometimes the model may give an incorrect variant or miss an alternative. Make sure the examples correspond to the stated level and do not contain unfamiliar vocabulary. If the exercises are too similar, add your own or generate another variant with a different format.
Refinement may include: replacing examples with ones closer to your audience, condensing or expanding the explanation, adding hints, changing the order of exercises. If you use the material for a lesson, add instructions and time limits. If for self-study, make sure the answer key is understandable without additional explanations.
Do not forget the limitations: the tool does not check your answers, does not save history and does not adapt to your edits. All changes are made manually in your text editor. The result may contain errors, so final verification is mandatory. If you doubt the rule, refer to an authoritative textbook or dictionary.
After generation you can manually replace the example "I have lost my key" with "I have lost my passport" if the lesson topic is travel. Or add an exercise on translation that was not in the generated set.
How to check the result
Checking consists of three steps. First: read the explanation and make sure it contains no factual errors. For example, the rule of Present Perfect must not assert that it is used with a specific time indication in the past. Second: check the exercises - do they all relate to the stated rule, are there any ambiguous formulations. Third: verify the answer key with each exercise. If the answer can be interpreted in two ways, it is better to rephrase the task.
It is useful to check whether the result corresponds to the stated audience. For A2 level the explanation should not contain terms like "perfect aspect" without explanation. For children the examples should be simple and specific. If you specified a business context, make sure the examples are really from business correspondence, not everyday life.
Finally, check technical limitations: the text must not exceed 8000 characters on input, and the result must not be too voluminous for your needs. If necessary, shorten or divide the material into parts. Remember that the tool is not intended for automatic knowledge checking: it only helps create a draft of explanation and exercises.
Checking an exercise: "I ___ (see) him yesterday". The key should be "saw", not "have seen". If the key says "have seen", this is an error that must be corrected manually.
Limitations and typical errors
The tool is not a chat and does not maintain a dialogue. It does not remember previous requests, does not compare variants and does not save results. Each generation is independent. You cannot upload a document, recognize text from an image or process multiple requests in batch. No DOCX or PDF export, only TXT. No automatic saving, integrations or publication. All this is important to consider when planning your work.
Typical errors when using: too general request ("explain grammar"), absence of level indication, request to do too much at once. The model may make mistakes in rules, especially in subtle cases, and give an incorrect key. Do not use generated exercises without verification. Also do not expect the tool to adapt material to your previous edits - it does not do that.
Another limitation: the tool is not intended for financial, medical or legal consultations. If you are studying grammar on examples from these spheres, the material must remain educational and not replace professional advice. All examples in the article are fictional and are not recommendations.
Error: request "make an English lesson" without specifying the rule and level. Better: "Explain the 2nd conditional rule for level B1, create 8 exercises and key".
The "Grammar practice" tool is a generator of drafts of explanations and exercises, not a ready-made course. To get different variants, change the audience, exercise format and volume. Compare three approaches: for beginners, for continuing students and for teachers. Choose the best, refine manually and always check the answer key. Remember the limitations: one result per generation, no saving or comparing, only TXT output. Use the tool as an assistant, but responsibility for the accuracy of the material remains with you.
