Integer Unit Activator The unit begins with a discussion of opposite words Eventually leading to a discussion of positive and negative being opposites The Touchdown Game

Using Manipulatives Rules of the road to make manipulative use more productive. Classroom Management Rules Let them play. Provide a designated work space to provide focus. Zero Tolerance Concept Development Let the children experiment and come up with their own ideas. Keep using the models for as long as necessary
