A Guessing Game

On Sunday, we took a walk and gathered some more rocks.  Today, we made a guessing game with these rocks.  We had twenty rocks in all.  We took took turns putting a few rocks in a large, lidded, empty yogurt container (the other person had their eyes closed during this).  Then we gave the container to the other person, who would then shake the container and guess how many rocks were inside.  Then the lid would be opened and the rocks counted.  We got the number of rocks right very few times, but Arin still thought this was great fun.  She also insisted on counting the amount of rocks for both of our turns, which I was happy about because it gave her counting practice.
