This very short video

walks the student to different time markers. 

At (four o'clock) 

in (the morning)

on (Wednesdays).

I used it to introduce times to my year 5 students so that they would find it easy to talk about their own routines in the video conference that followed.

I also find "Plotagon useful", because what is badly missing in homeschooling is the audio input students may not be exposed to as often as they would be in a normal class setting.
