Old MacDonald had a farm, E I E I O. On another day... he also had a band!
Check out these neat and very durable wooden sound puzzles below. I use them a lot with younger children and they LOVE them! The animal sounds made when the puzzle piece is correctly placed in the space encourage language development (children often will repeat/say animal sounds before words). Matching skills, labeling, and eye-hand coordination are also practiced. You can also easily clean the wooden pieces with clorox wipes which makes these puzzles all the more amazing!
You can find these sound puzzles at numerous places online, including www.MelissaandDoug.com and www.GummyLump.com
