The kids really like stars. I think their two favourite shapes at the moment are stars and love hearts. L, in particular, is going through a stage of drawing love hearts and stars on everything. So a simple post-dinner activity was placing star stickers onto a cardboard star.
I drew the stars on a sheet of cardboard and cut them out, then I let the kids loose with two star shapes each, and several sheets of star stickers. A placed random stars all over hers, while L used the stars to make patterns, and even a face on one cardboard star. She also layered some of the stickers to make some stars with lots of points.
Once they were finished placing stickers, we taped some thick pink paper strips to the top of the stars to hang them by.
