A parade of these valentines comes equipped to treat a whole group of classmates -- just pull a tail, and you'll have a sweet lollipop in hand.
Cut a heart shape from red construction paper (it should measure about five inches at the widest point).
Fold the heart in half to form the mouse's body, then glue together the edges from the tip of the nose to the top of the back, but leave the tail end open.
For ears, cut out a pair of small pink paper hearts, fold them in half, and then glue them onto the body. Draw on eyes with a colored marker.
Lastly, tuck a lollipop into the body, so that the stick becomes the mouse's tail.
