Above are two versions of the same video (description below). The left-hand video includes standard (monophonic) audio and the right-hand video includes spatial (ambisonic) audio. Ambisonic audio allows fo the spatial/directional aspect of sound to be recorded. This allows for a more immersive experience. You will need to use headphones or earbuds in viewing the videos to hear the difference.
In this video, a 4th grade class is reviewing their understanding of fraction comparison. The video includes students working on two separate tasks: determining less than / greater than / equal to for 3/8 & 1/3, and then 2/3 & 3/4.
