I first taped one of each shape onto the wall for Johan to follow. He's pretty much too excited to stick all the shapes that I can see him getting impatient with me while I cut the tape and give him just one shape at a time.
I love it that he tells me the shape before taping it to the wall and even though they're not in perfect alignment, I am just too proud that my son already knows his shapes. This might be a good idea to teach him the alphabet, too, don't you think?
We'll do it next time and maybe colors too.
