As a teacher of little kids, you need to be artistic & creative. I have tried this art activity with my class. Before this activity, you need to get a pig piece of sponge,not too thick, draw different shapes on it and cut them out.prepare the class for art time and begin!!
making pictures with different colors and shapes made from sponges make circles, triangles and squares, hearts, stars, rectangles, ovals (ask the children to be creative with paint and shapes) for example they can make a rainbow with the different shapes and colors of paint. My class enjoyed this activity, at the end of the day, I was amazed at all the new vocabulary they learned, Try it out especially with young learners, have fun!!
