The first unit in your child¡¯s mathematics class this year is Variables and

Patterns: Introducing Algebra. This is the first formal unit of the Connected

Mathematics? algebra strand.

UNIT GOALS

This unit¡¯s focus is on ways to describe situations that change. In the first part of

the unit, students explore three ways of representing a changing situation: with

a description in words, with a data table, and with a graph. These representations

are compared to one another to elicit the strengths of each presentation.

Students learn to write symbolic expressions as a shorter, quicker way to give a

summary of the relationship between two variables. After writing symbolic rules,

students learn how to use graphing calculators to make tables and graphs for a

given rule, which allows students to interpret and compare more data sets.
