My fourth graders started our African studies in Morocco. They learned about radial symmetry that is found in Moroccan tiles and then created their own radial design using a design sheet.
Once they were happy with their designs, they were asked to go over their lines again, as dark as they could.
Their dark designs were then taped to their tile with the pencil side facing the tile. They scribbled on the back of the paper as hard as they could to transfer the image onto the tile. Next, they used Sharpies to color their design.
To finish the tiles, they glued a piece of felt to the bottom of the tile and I sprayed them with spray Mod Podge. I had to be very careful to spray a tiny layer first and let it dry before spraying 2-3 more thin layers. If the layer got too thick, the Sharpie would bleed.
