Based on your needs, Pedagogical seems to be a great fit. It offers a variety of tools that can assist you in creating a differentiated worksheet on global trade for your grade 10 students.

One of the key features of Pedagogical is the ability to create assessable content. This means you can easily turn your classroom materials into quizzes or summaries, which can be particularly useful for creating differentiated worksheets. You can incorporate various content types like images, PowerPoint slides, Word documents, PDFs, and YouTube videos into your worksheets, making them more engaging and tailored to different learning styles.

Another useful feature is the Lesson Content Extraction. This allows you to use your existing lesson materials to enhance the worksheets, offering students actionable insights. For instance, you could extract key points from your lessons on global trade and incorporate them into the worksheets.

Additionally, Pedagogical allows you to add instructional diagrams to your worksheets. This could be particularly useful for explaining complex topics related to global trade. You could create flow charts or mind maps to help students understand the flow of goods, services, and resources in global trade.

Lastly, Pedagogical offers a free plan that includes all these features and allows you to extract up to 5000 words. If you need more, there's an upgraded plan that increases the word limit to 100,000 words. Please note that the software is still in beta, so there might be some bugs or incomplete features. However, given its array of features and free pricing tier, it could be a valuable tool for your teaching needs.
