Make some different farm animal masks for your children to wear. You could also copy some animals off the internet and turn them into headbands.
Put one on your child so they can’t see what animal they are wearing. Provide clues one at a time until they can guess what animal they are. (i.e. You have 4 feet. You are pink. You roll in the mud. You say, “Oink.”)
Your children can then play farm animals with the masks or headbands.
