Here is another idea for a Valentine's Day card or sign.
Materials Needed: scissors, large drawing paper, colored cardstock, acrylic paint (we used green red, and purple), paper plates, markers, and glue. At the beginning we only were going to use these materials... so the planned changed a bit. The bolded materials are the ones not pictured.
1. Pour paint onto paper plates. I used one paper plate per color. We also used one color paint at a time and cleaned up after each color so that we didn't get too much mixing.
2. Encourage your child to cover the large drawing paper with handprints, fingerprints, etc.
3. Switch to the next color and repeat.
4. When we were done we had three papers covered with paint. We let the paint dry overnight (since we did this right before bed).
5. On another piece of large drawing paper, I worked with my son to draw long lines (they would be the flower stems). Mostly he just covered the paper with green marker, which worked perfectly for what we were doing.
6. While your child draws green lines, you can cut hearts out of the painted papers.
7. Next, cut the paper covered in green marker lines into strips to make stems.
8. Have your child help you glue the green strips (stems) in place on the large drawing paper.
9. Glue the red and purple hearts to the tops of the stems. You could also cut leaves out and glue them on. (We didn't make it that far this time)
10. Draw a vase by making a design on one side of a folded colored piece of paper.
11. Cut the vase out.
12. Glue the vase on top of the stems.
13. Let the picture dry and then write a message to a friend on the vase... or just hang up the beautiful bouquet of love in your house!
My toddler wasn't too helpful with the gluing/cutting this project required... but he LOVED the painting and drawing parts, so that kept him occupied while I cut and glued. Older kids could probably glue, cut, and place the pieces of this project independently. This project would also be a great way to teach symmetry to older kids... since you use principles of symmetry to cut the hearts and the vase.
We worked on practicing saying "I love you!" while we made this project. We also talked about sizes since the hearts and strips of paper were cut to be big and small. Trying to expand language a bit by saying, "big red heart" instead of just "big heart" was fun. We also talked about thick lines and big dots when my son was drawing lines and other shapes with the markers to make stems.
