Based on your query, I would recommend using Nolej for planning your class exercises. This tool can take your existing content and transform it into interactive "micro-learning packages". These packages can include quizzes, flashcards, and glossaries, which can make your class exercises more engaging and effective.

The Activity Generation feature of Nolej allows you to create a variety of activities such as multiple-choice questions, fill-in-the-blanks, True/False questions, and even games. This can help you diversify your class exercises and cater to different learning styles.

Additionally, Nolej offers Customizable Assessments. This feature allows you to tailor assessments to align with specific learning goals, which can help keep students more engaged during class exercises.

Finally, Nolej integrates with popular learning platforms such as Google Classroom, Moodle, Microsoft Teams, and Canvas. This means you can easily distribute the interactive class exercises to your students through these platforms.

In conclusion, Nolej offers a range of features that can help you plan and execute effective class exercises.
