Algebra (Class 11)
Overview
In today’s class we practice with solving equations by drawing balances and recording our solution process using algebraic notation. In addition we continue our work with input/output tables, graphs, equations, and situations where these ideas arise. In the last part of the block we take Test 2 which focuses on the material from our second unit.

Key Ideas
A balance can be used to represent and solve algebraic equations.
Groups of objects can be represented on the balance and in equations.
Un-grouping by using the distributive property to expand an equation is a necessary step in solving equations using algebraic notation.
Input/Output tables can be used to represent situations and can be turned into coordinate graphs.
