# Decimal Squares in Guided Math Groups

Decimals is a tough concept for many of our students. It is so important that we spend some time building conceptual understanding and problem solving as well as the procedural fluency. I think a great way to start is based on the work of Dr. Bennett from the University of New Hampshire (http://www.decimalsquares.com/). Decimal squares is a way for students to visualize what they are talking about and to develop conceptual understanding.

Hi Dr. Nicki,

The visual representation of the decimal numbers on the decimal squares website and the videos from a few of the others gave me plenty of resources for our upper elementary students. Many times I have tried to use a overhead hundred square manipulative and label it or draw on it to represent hundredths and thousandths. Not an easy task. In CT, one of the state grade level expectations includes decimal numbers, so this is the way to go. The key to using the virtual manipulatives is planning and comfort level. I am figuring that once the teachers see how engaged the students will be, then they will want to utilize this resource. Many thanks.
