Expressions and Equations

# Online Interactives:

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!**

Poses problems, has students model with algebra tiles and solve, tells them if they are correct or incorrect.

Balancing Scales to Solve Equations
