There is and will be a lot of visualizing work happening in Kindergarten and 1st Grade with the upcoming poetry units.
I found this very cute poem/song:
KATALINA MATALINA UPSADINA WALKADINA HOCA POCA LOCA
If you google it, you will find a lot of blog posts, ideas, etc. There is also music floating around for it if anyone wants to play it.
Here's one link: http://drjeanandfriends.blogspot.com/2011/07/katalina-matalina-upsadina-walkadina.html
It works really well for having children listen, visualize, illustrate on a really simple, concrete level and it's a good starting point.
Green Giant, by Jack Prelutsky is also a good concrete poem to use for visualizing.
This blog post has some great poems, graphic organizers and chart ideas as well.
Here's a Pinterest board with great chart ideas for visualization and making mental pictures:
Do some googling and see what else you find. If you come up with great ideas... SHARE :)
