Songs with motions and movement are excellent for toddlers, Pre-K'ers, Kindergartners, older kids, etc., because movements enhance learning. Those who may not be so quick to pick up a melody may still be able to do simple motions in rhythm, thus still providing great training in musical ideas and patterns.
So, for this activity, grab your kiddo/s and sing through "Row, Row, Row Your Boat" (If you don't know it, just type the name into Google. I would have put a link on, but they're all so cheesy I couldn't bring myself to do it. So, find one if you need to... and I apologize in advance for the cheesiness).
Here's what we used:
1. Laundry baskets (if you're doing this with a class or more kids than you have baskets for, you can stop into any wholesale club like COSTCO, BJ's, etc. and grab some of their many empty, low-sided boxes)
2. Stick for the mast (wrapping paper role or a stick from your yard)
3. Paper and markers for creating a flag or sail.
4. "rowing" devise (large wooden spoon, etc.)
5. Clear packing tape.
After the kids know the song, have them create a flag for their boat and then tape flag to their mast, and tape mast to boat.
If you have a blue blanket of some sort, that would be great for water. Ours was a little small, but it still worked OK.
Here they are with "hide" your boat, I think... or maybe it was "sleep" your boat...
You certainly don't need a boat to do these - they will be just fine being creative with this no matter what!
After we were done singing, the boys continued to play in their boats for a while - it was neat to listen to their imaginative play. :-)
Be creative and have fun! :-)
