I agree with Samuel. This was a great idea for using drag and drop, sharing vocabulary when the student drops the item in the right place. I had some trouble, however, know what was the right place. Perhaps some other visual cues? There was no logical reason to me why the cat should be in the middle of the road, or the bird should be where it was. If you are dealing with very young children, you might have the target be a shadow of the shape you want them to drop. If older children, you could place things around the drop spot which make the drop item more obvious ( a nest or another tree for the bird, a ball of yarn or a mouse for the cat, some acorns on the ground for the tree?)
These are just my thoughts and I hope you know that I wouldn't offer them unless I thought they would be helpful for your development.
