Expressions and Equations

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.)

â€‹

â€‹

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

â€‹

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

â€‹

Balancing Scales to Solve Equations

(PBS Media Learning)

Interactive opportunity to balance a scale.

â€‹

Modeling and Solving Two-Step Equations (Gizmos)

â€‹

Smallest Solution (Desmos)

Solving multi-step equations with variables on both sides. Algebraic thinking and justifying.

â€‹

Real World Expressions and Equations (PBS)

A fantastic task about the fairness of tipping formulas. Video-launched. Best launched synchronously.

â€‹

Central Park (Desmos)

This experience contains a series of scaffolds leading students to be able to write an equation for a linear relationship. It is an older Desmos task with some missing features so might be better used synchronously so you can provide instruction.

â€‹

Picture Perfect (Desmos)

This experience is engaging and challenging. Students go generate linear equations that match a “hanging picture frames” context. Scaffolding makes the algebra accessible.

â€‹

Classification of Solutions (Desmos)

Solve multi-step linear equations and classify them.
