In my opinion, the divisibility module does not assess students' ability to check for divisibility. It does not give students the practice to recognize which numbers are divisible by which. It skips the foundation of divisibility and goes on to a higher level, as does the video. Students recognized this through frustration because they could not understand the divisibility video without having the foundations of divisibility (until I explained). Example below:
Perhaps a Divisibility 0.5 module could be added to address the fundamentals?
