Students will learn to determine whether a given
number is a solution of an equation.

Evaluate the side of the equation containing
the variable by substituting a given value
for the variable, simplifying the expression,
and comparing the answer with the
number on the other side of the equal sign.
If they match, the given value is a solution.

Materials for each student:
graph paper
straight edge
colored pencils (optional)
create a worksheet page with grids of 10 X 10 (optional)

Students will practice algebraic reasoning with M&Ms by extending patterns, creating multiple representations of data, and formulating equations from problem situations.
