Number Sentence - Equations (Desmos)

The title doesn’t capture what this task is about.  It focuses on matching algebraic expressions to contexts and word descriptions.  It is a worthwhile task.

Equivalent Expressions (Desmos)

Pool Border Problem (Desmos)

Students explore different ways to find the number of tiles in the border of a square swimming pool.  They discover that the expressions they generate are all equivalent. (You would probably need to introduce this during a synchronous lesson and then have students work on it.)

Enter algebraic or numeric expressions and compare. **Really cool modeling!**
