We love to collect tons of seashells at the beach and bring the home with us! How about adding them to your next math lesson with this measuring seashells math activity invitation! The beach is a wonderful play full of learning opportunities of all kinds. A sensory filled environment, the ocean is an amazing resource for hands on learning activities. Read all about hands-on beach and ocean learning ideas for families.
Next time you are at the beach, collect a bunch of shells. We specifically spent a morning hunting for different sizes of the same kind of shells. It made for a great scavenger hunt to try to find different sizes. Our beach has tons of scallop shells and clam shells! You can see what we collected while we were on the beach. This simple measuring seashells math activity was also a terrific, unplanned math activity!
At home I set out our seashells and a mini tape measure. Together we measured the shells and put them out in order of size. Some were very close in size, so I showed him how we use the spaces between the numbers on the measuring tape. I had the opportunity to introduce 1/4, 1/2 and 3/4 increments.
We also gathered clam shells of all sizes and measured those for our measuring seashells math activity.
Measuring the shells and deciding which was smaller or bigger than the last one turned out to be a perfect simple math activity!
He also wanted to line up various size shells and see how long they all were together. He enjoyed exploring the shells and tape measure in many ways of his own choosing which made it a very playful math activity for him. We discussed a few easy math facts, but I was happy to let him explore and discover on his own. At his age, I enjoy sharing a love of the math activity as much as learning something specific from it.
There are so many fun ways to use the items around you to create a simple math activity like these seashells!
