Make your own lift the flap game on the bottom of a laundry basket or low shelf/table. Contact paper pictures of animals you saw at the zoo to the surface. Laminate the closer pictures and then tape on side down on top of the matching animal. This gives your child practice standing, while they work on lifting flaps and recognizing animals.
Pictures of animal - close and far
Try with pictures of other things, for instance - up close pictures of you and your family or other household items.
