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.)
​
​
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
(PBS Media Learning)
Interactive opportunity to balance a scale.
​
Modeling and Solving Two-Step Equations (Gizmos)
​
Smallest Solution (Desmos)
Solving multi-step equations with variables on both sides. Algebraic thinking and justifying.
​
Real World Expressions and Equations (PBS)
A fantastic task about the fairness of tipping formulas. Video-launched. Best launched synchronously.
​
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.
​
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.
​
Classification of Solutions (Desmos)
Solve multi-step linear equations and classify them.
​
Video Game: Dragon Box (algebra 12+)
Teaches all the rules for solving algebraic equations but does it visually in a virtual video game environment..
