One day at the beach in Costa Rica my daughter and I were digging in the sand making sandcastles when we ran across a live sand dollar. Finding a dead exoskeleton would have been exciting but finding a live sand dollar was unbelievable!
We held it in our hands and felt the tiny hairs on the underside of it's body tickle our skin ans the animal tried to get away from us and wiggle it's way back down into the sand. We turned it over and watched it's mouth moving in the center of it's flat body.We set it down in the sand and watched it filter sand and water through it's body and out the five holes that radiate out from the center.
Then we started to feel just under the surface of the sand as the tide washes the waves back and forth and began to find more sand dollars. At first we found one or two. Then we found them by the tens. We soon realized that there were hundreds, thousands and possibly millions of sand dollars right there on that beach.
Talk about a teaching moment!
We spent the rest of the day observing, drawing, measuring and counting sand dollars. This lens is about the math that can be learned at the beach while observing sand dollarsl

Pick the biggest pumpkin you can find. Cut off the top and smell the fresh pumpkin smell. Carving a Jack O'Lantern leads into a mathematical unit study of place value that incorporates all five senses.
Counting pumpkin seeds into groups of 10's, 100's etc. helps children understand our decimal system and prepares them in a concrete way to understand higher level math.
Scoop out those seeds, roast them if you like and count your way into a concrete understanding of place value.
