Have children draw or paint a portrait of someone that they love. Use any medium, such as acrylic craft paints or crayons. Additionally, have them decorate a frame in which to place the portrait. Purchase plain wooden frames from any art or craft store and instruct children to decorate them with the design and words of their choice. This is a good Valentine's Day gift for the individual in the portrait.
Have children create a collage of photos and art that represents love. Give each child a piece of poster board. Instruct the children to go through magazines and cut out photos, bring photos from home and draw or paint their own art work. Children arrange the images on the poster board in the manner of their choosing. Have children share their posters with their peers and hang up the collages as Valentine's Day decorations.
