Publication details: Melissa & DougDescription: Small plastic pegs help children grasp and manipulate the eight illustrated pieces (farmer, cow, pig, horse, chickens, ducks, dog, and sheep). Match the pieces to the pictures on the illustrated wooden puzzle board to hear Old MacDonald start the song ("Old MacDonald had a farm, E-I-E-I-O!"). Each animal completes its part of the song. For example, the pig sings, "And on that farm he had a pig, E-I-E-I-O". Bulk up the plastic pegs as needed to give every child an opportunity to participate in "singing" this song with their peers. Requires 3 AAA batteries (not included)Online resources:
