Case Study

Look at $y + 9 = 2y - 3$ . Name this statement, name the symbol linking the two sides, and state what that symbol claims about them.

Case context: A student writes $y + 9 = 2y - 3$ and wants to describe it with correct algebra terms.

Question: Look at $y + 9 = 2y - 3$ . Name this statement, name the symbol linking the two sides, and state what that symbol claims about them.

Sample answer: It is an equation. The linking symbol is the equal sign, $=$ . It claims that the left side, $y + 9$ , and the right side, $2y - 3$ , have the same value.

Key points:

The statement is an equation.
The linking symbol is the equal sign, $=$ .
The equal sign claims both sides have the same value.
An equation links two expressions into one claim about equality.

Rubric: Full credit: names it as an equation, identifies the equal sign ( $=$ ) as the linking symbol, and states that both sides have the same value. Partial credit: gives one or two of these correctly. No credit: none correct.
