Pioneer Children Sang as they Walked
 

(Credit Unknown) I always bring a few props/actions for them, and let them act out the different things:

"washed at streams" - small towel
"worked" - rubber mallet or other tool
"played" - ball or other simple toy
"camped" - make a tent with hands
"read" - book
"prayed" - praying hands

We also usually walk in place, or around the room when we can. (This is especially effective with Junior Primary)
