I made a square and asked him to make one like mine.
After I created a triangle and he made one the same as mine.
I arranged the stick looking like a boot and he followed me.
Then he made an "X" and asked me to do like his.
He asked me to make a pirate boat. I first made one and gave him the instructions, then he made one exactly the one I had made before.
We also played at the sandpit drawing circles, boys, stars and houses. I didn't take pictures because the sun was amazingly bright and it wouldn't capture the picture on my phone. It was a great day at the playground. We didn't need to spend any money on this activity, and we practiced mathematics, shape making, and hand and eye coordination.
