ab: Summary: Classroom teachers try to provide opportunities for students to
practice and use the algebra skills they are learning in ways that are
nonroutine. They also want to help students connect the big ideas of
math with the skills they are learning as part of the balance between
understanding concepts and procedures. Math games can be used to
accomplish these goals. Exponent Rummy was designed for students to use
the properties of integer exponents to simplify expressions with a
variable base. Such practice can help them increase procedural fluency
as they practice manipulating the symbols. It is appropriate for
students to practice when they are learning these properties and also
later as review. The specific exponents shown in the cards were chosen
on purpose so that students could both work mentally and increase their
facility with exponents. This article describes how one class used the
cards for two different integer exponent activities. Two activity
sheets are included. (ERIC)
