Ideas at Work: Brace for measuring bracelets

by Mary Hynes-Berry

In early November, Erikson Early Math Team members made several presentations at NAEYC’s annual conference. In a three-hour session, instructors Rebeca Itzkowich and Mary Hynes-Berry had participants engaged in exploring Big Ideas about measurement as they used both direct and indirect measurements in order to figure out how long a piece of leather would need to be to make a lovely tree “bracelet.” They later turned their adding machine tape lengths into rulers with arbitrary units so they could determine not just which tree girth was bigger, but how much bigger it was.

As further proof that math is all around us, we were delighted to see that in December examples of “yarn bombing” or knitting cozies for trees showed up in Evanston! We’re sure there was all kinds of measuring involved.

It’s working

We’re making a difference in children’s math skills. Our research shows that children in the classrooms of teachers in the project learn more about math during the school year than children whose teachers did not participate.
