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)
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. **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
(PBS Media Learning)
Interactive opportunity to balance a scale.
