I made this activity up as a means of improving the kids' hand/eye coordination skills. There are 5 pages to choose from.
If the target is hit, it will become animated and make a sound. The kids can use their finger, a koosh ball, tennis ball, foam ball, etc. So long as it's got some weight to it, is not too hard or with a jagged/sharp edge, you'll be in business.
The kids like the elephant in slide 6. To make it "disappear" again, just go back one slide (using the arrow symbol if you're in full screen mode) to the birds and then right back to the land animals. The elephant will be "hidden" again.
