This is cute, simple, and fun!
There are many different things that you can make with these, but my favorite is the heart wreath. You will need a thin, white paper plate. You will need to cut out the inside so you have the outside circle of the plate left. Have the kids color the white part of the plate before gluing on the hearts using Valentine colors. The kids will color code the hearts using the chart provided. After they are colored, they will need to be cut out and glued to the plate.
You could also have them color code the hearts, cut them and simply glue them on a BIG HEART cut out of construction paper to give to mom. They could write a sweet note on the other side of it or they could put their hand print on the other side!
