What happened to the sound of the voices for the metric family? I cannot get any sound for this part and I really thought that helped my students remember their place in the family.
Unfortunately this object was created using Flash which is no longer supported by Apple devices and several Internet browsers. We had to convert this object so it can be viewed on Apple devices. In the conversion the audio for the voices was lost. We plan on rebuilding many of the popular learning objects in the future and I will add this to that list. Thanks!
