Create 10 practical templates for interactive teaching units that teachers can use in the digital classroom to make lessons varied, participatory, and conducive to learning.

Context: [digital classroom, interactive teaching, e-learning, teaching methods, digital media, student participation, lesson design, pedagogy, motivation, school teaching]

Goal: [active student participation, motivating learning, varied teaching methods, effective use of digital tools, promotion of independence and creativity]

For each template, explain:
1) a concrete description of the teaching unit including topic and procedure
2) digital tools or media used
3) the expected benefit for learning motivation, understanding, and collaboration

The templates should:
- be adaptable for different school levels and subjects
- support both synchronous and asynchronous teaching
- consider simple to advanced digital tools
- relieve teachers in planning and conducting digital teaching units
