Sophia spent two days this week collecting shells at two different lakes in the area.
She collected them and kept them in a few mason jars for a bit. Then she washed the shells. Then she decided to let them sit in the sun for a bit. Then she decided it was time to spread them out to dry. After dumping them all out on the deck, she decided to count them all.
All in all she collected 342 shells. Yes, that's three hundred and forty-two shells. She counted them one-by-one and other than a few interruptions from her brothers, I'm pretty sure her estimate is fairly accurate.
This is whatI like to call summer math.
