Very young children need easy art projects. Draw outlines of several different kinds of flowers, fruits or animals. Photocopy enough for all the kids, and teach them their colors by having them fill in each shape with a certain color. For example, coloring in a drawing of an apple can help them learn the color red. As they advance in skills, you can add two, three or four objects and have them use a variety of colors. This same idea works with the alphabet. If you combine flowers, fruits and animals with the alphabet, you can create a semester-long project where they learn letters while coloring them with bingo markers.
This age group is ready for more challenging projects. Making cards for holidays or any occasion is a great activity with bingo markers. The children can make their own designs using stencils, or simply let them create something freehand. You can also print out designs found online. Many websites have free projects available.
Scrapbooking is a great activity as kids reach fourth and fifth grade. Using blank paper, a three-hole punch and yarn, they can create small books. Have them bring photos from home. Give them glue to paste down the pictures, then let them use bingo markers to decorate their scrapbooks.
Kids in seventh and eighth grade are ready for more complex projects. Why not make a time capsule? They're looking forward to their future, thinking about high school and maybe even college. Any type of box or mailing tube will work. Let them decide what to use. Over the course of a week or two, have them journal their reflections on life in junior high. They can use bingo markers to decorate their diary and the outside of the time capsule. Write things such as, "Do not open until you're 18" in big, colorful lettering on the time capsules.
