*Algebraic ThinkingEquality
*Outcomes: *Participants will establish that
students have some very common misconceptions about the meaning and use of the equal sign
*Participants will explore strategies to help students develop an understanding of the meaning and use of the equal sign.
*Participants will develop an understanding of the importance of the concept of equality in algebraic reasoning.
*Reading:
*Read forward and chapter 1
*Use notecards to record important statements

*While Person #1 reports, other group members listen, but do not question Person#1, comment, or give clues.
*When Person #1 finishes, Person #2 reports while the group listens.
*Repeat until all group members have reported all of their ideas.
*The group discusses ideas that were reported.
