Algebra 1
Teach linear equations and inequalities, exponential functions, data, and more, with these Desmos favorites, as well as free lessons come from our complete, standards-aligned math program, Amplify Desmos Math.
Grades: 8th - 10th Grade

Patterns and Sequences
Students model, compare, and contrast arithmetic and geometric sequences using tables, recursive definitions, expressions, and graphs.
- Visual Patterns
- Sequence Carnival
- More Visual Patterns
Linear Equations and Inequalities
Students solve linear equations with one variable and interpret solutions in context, and extend their knowledge to make sense of multi-variable equations and create representations of linear relationships.
- Working Backwards
- Solving Strategies
- Same Position
- Various Variables
- Subway Seats
- Shelley the Snail
- Five Representations
- Pizza Delivery
Describing Data
Students compare and contrast data sets using standard deviation and use the correlation coefficient and lines of best fit to describe the relationship between two variables. They also consider whether the relationship represents causation or correlation.
- Finding Desmo
- Correlation Coefficient
- How Hot Is It?
- City Slopes
- Residual Fruit
- Penguin Populations
- Behind the Headlines
- City Data
- City Data (Digital Companion)
Describing Functions
Students describe and create graphs of functions using their key features, including domain, range, and average rate of change. They make sense of piecewise-defined functions and make connections between a function and its inverse using graphs.
- Plane, Train, and Automobile
- Craft-a-Graph
- Pumpkin Prices
- Chip the Robot
Systems of Linear Equations and Inequalities
Students are introduced to systems of equations and graphing systems of linear equations. They'll progress to writing systems of linear inequalities and exploring solution regions.
- Shape It Up
- Lizard Lines
- Quilts
- Seeking Solutions
Exponential Functions
Students are introduced to equations of exponential relationships and then apply that by modeling data (including exponential data).
- Carlos's Fish
- Detroit's Population, Part 1
- Detroit's Population, Part 2
Quadratic Functions
Students are introduced to quadratic functions, and learn whether a function is linear, quadratic, or exponential. They'll identify and interpret key features in graphs and tables and graph quadratic functions written in factored form.
- Revisiting Visual Patterns
- Quadratic Visual Patterns
- Sorting Relationships
- On the Fence
- Stomp Rockets
- Plenty of Parabolas
- Robot Launch
- Two for One
- Parabola Zapper
Quadratic Equations
Students determine the `x`-intercepts of quadratic functions written in factored form and standard form. They'll learn to solve quadratic equations in context, and compare and contrast strategies for solving.
- Shooting Stars
- Square Tactic
- Stomp Rockets in Space
