Here are some ideas for Singing Time Games. You could play these games the last few weeks of March, since General Conference is on Easter Sunday. So, here you go, hope you like them.
Easter Egg Hot & Cold Game
Have a basket full of eggs. Inside the eggs have pieces of paper with songs written on them.
I Know That My Savior Loves Me
He Sent His Son
Follow the Prophet
Easter Hosanna (this is what the children in my ward are singing for Easter)
On some of the pieces of paper, have a song along with a description of how to sing that song.
Follow the Prophet: Girls Only!
He Sent His Son: Nose Plugged
Follow the Prophet: Standing Up
I Know That My Savior Loves Me: Hands on your head.
Choose a child to go out into the hall. Choose another child to come pick an egg out of the Easter Basket. Have the child hide the egg somewhere in the room (don't have them open the egg. When the child finds the egg, that will be the next song that the children will sing.) Once the chld has hidden the egg have him sit down. Choose a song for the children to sing (after this the song will be chosen by what is inside the egg). When the children begin singing have the child, that is out in the hall, come in. As the child gets closer to the egg, have the children sing louder. As the child gets farther away, have the children sing quietly. Sing until the egg is found. Once the child has found the egg, have him open the egg to reveal the next song.
Pass the Egg (Hot Potato)
Once again, have a basket full of eggs with songs inside them. Choose a song to begin the game. Once the children begin singing pass the egg to one of the children. Have the children pass the egg around until the music stops. Whoever is holding the egg, when the music stops, must tell you what the next word is. Continue doing this until you have sung the song. Once the song is finished, have the child who is holding the egg, open it and reveal the next song.
If you want, you could just practice Follow the Prophet, and have different singing descriptions inside the egg. So, if the child holding the egg tells you the next word, have them open it and tell the children how they will sing 'Follow the Prophet' (nose plugged, standing up, teachers only, etc.)
Have some buckets or easter baskets, as many as you would like, at the front of the room (you could have 3 in a row, or a few buckets in a bunch). In the bottom of each bucket have a piece of paper with different amounts of points (5 points, 10 points, 15 points, etc.). Have the children begin singing. Have the pianist stop playing the music after a little while. Call on one of the children to tell you what the next word is. If they answer correctly, have them come up to the front. Hand them a plastic egg, and have them toss it into one of the buckets. Whatever bucket it lands in, that is how many points they get. If they don't answer correctly, they don't get to toss the egg. You could split the primary into groups and take turns choosing from each team. You could have children against teachers, boys against girls, etc.
(Instead of an egg you could use a beanbag, a ball, a wadded up piece of paper, etc.)
For the child finding the egg or tossing the egg: you could have them wear some bunny ears, that would be really fun! You could probably find some at a store, or you could just make some using construction paper for the ears, and attach them to a head band.
And, instead of having them tell you the next word, you could always come up with a few questions that have to do with the song.
Who was the first prophet? (Adam)
Adam lived in a place called? (Eden)
Enoch's people were so righteous that Heavenly Father did what? (Took them up to live with Him.)
Abraham the prophet prayed to have what? (a son)
