How long is the duration of the unit where Ms. Jackson supports students with spreadsheets?

The correct answer indicates that the duration of the unit where Ms. Jackson supports students with spreadsheets is 12 days. This timeframe suggests a thorough and comprehensive approach to learning, allowing for ample time to introduce spreadsheet concepts, engage students in hands-on practice, and provide opportunities for collaborative learning and feedback.

In a 12-day unit, Ms. Jackson can cover various aspects of spreadsheet skills, such as basic functions, formula creation, data visualization, and possibly even advanced techniques. This extended period supports a deeper understanding and retention of the material, enabling students to develop proficiency rather than just a surface-level familiarity.

Shorter durations, such as 3 days, 5 days, or even 2 weeks, may not provide sufficient time for students to explore the complexity of spreadsheets fully or to apply their learning in meaningful projects. This thorough engagement is critical in a subject where practical application is key to mastering the content. Thus, the choice of 12 days reflects an ideal balance between instructional time and student learning outcomes.
