Based on your query, I would recommend Questionwell AI and RockettAI as they both offer features that can help you generate worksheets with auto-correcting math questions for grades 6 to 10.

Questionwell AI has a Question Generator feature that allows you to generate questions based on various inputs, including text, images, audio, or video. You can choose the topic, language, and question type (multiple choice, fill-in-the-blank, or short answer). This could be particularly useful for creating diverse math questions. Additionally, the Export feature allows you to export the questions to various platforms or print them as a PDF, which could be used as worksheets.

RockettAI, on the other hand, has a Worksheet Generator that creates customized worksheets tailored to the curriculum. This could be used in conjunction with the Repetitive Maths Practice feature, which offers interactive and adaptive practice exercises to reinforce essential math concepts. This combination could provide a comprehensive solution for creating auto-correcting math worksheets.

Both platforms offer free trials, so you can try them out and see which one best fits your needs.
