Member Jaymie Derden posted a note to me saying that her kids created hand and body movements to the hymn, "Here I am Lord" to study Samuel's call in the night.  This popular hymn is based on Isaiah 6:8 (Here I am Lord) and 1 Samuel 3 (I've heard you calling in the night).

The hand motions were not written down so you'll have to work with your kids to recreate them yourself. I would probably also discuss potential minor changes in the lyrics just to get the kids thinking more about Samuel's story 

Here's a nice contemporary sounding version on YouTube from Chris Bray, a well-known Catholic worship leader-artist. The video could definitely be projected on the wall or shown on your smart tv or computer screen as your teleprompter and music source. Videotape your kids performing it and then have fun watching it back again.

"Here I Am, Lord" was written in 1981 by Dan Schutte and is found in many modern hymnals, including The United Methodist Hymnal, and Presbyterian Hymnal, and many Catholic hymnals. 

Excerpt:

I, the Lord of sea and sky,
I have heard my people cry,
All who dwell in dark and sin
my hand will save.
I, who made the stars of night,
I will make their darkness bright.
Who will bear my light to them?
Whom shall I send?

Refrain: Here I am, Lord. Is it I Lord?
I have heard you calling in the night.
I will go, Lord, if you lead me.
I will hold your people in my heart.*

Comment: In many churches this hymn is sung with a quick, uplifting pace.
