In this ration & proportion for Algebra I worksheet, students answer twenty-three word problems involving ratio and proportion.
Here is an excellent, detailed resource that builds on prior work done in Algebra I on domain and range of a function. Learners review the concepts of domain and range, then work in pairs to complete a worksheet of exercises in which they determine domain and range of a relation given its graph and state whether the relation is a function. After discussing their solutions with the class, each pair then selects an item from a grab bag which contains exercises with instructions to sketch possible graphs for a given domain and range. Note that solutions to exercises are not included.
Using a regression applet, your class can predict and explore the shape of the residuals of linear and non-linear data. Then through discussion, these learners can generate rules on how to analyze residual plots to recognize non-linear data. Round out the lesson with an investigation regarding SAT scores and best fit regression models. For an extra challenge, have the class use the regression applet to try to generate scatter plots to match given residual plots. Note: the Data Sets for Algebra I Handout mentioned as an optional resource is not available.
In this Algebra I worksheet, 9th graders solve problems that cover a variety of Pre-algebra and Algebra I topics.  The one page interactive worksheet contains twenty multiple choice questions and is self checking.
For this Algebra I worksheet, 9th graders solve problems that cover a variety of Pre-algebra and Algebra I topics.  The one page interactive worksheet contains twenty multiple choice questions and is self checking.
Ninth graders explore applications of Algebra.  For this Algebra I lesson, studetns investigate eight applications of algebra ranging form the mathematics of roller coasters to tracking the popularity of a web site.
In this Algebra I worksheet, 9th graders solve problems involving a variety of pre-algebra and algebra topics, including interpreting graphs.  The one page interactive worksheet contains twenty multiple choice questions and is self checking.
In this Algebra I worksheet, 9th graders solve problems based on a variety of algebra skills, including simplifying algebraic expressions, reading and interpreting graphs, and factoring.  The one page interactive worksheet contains twenty multiple choice questions and is self checking.
In this Algebra I instructional activity, 9th graders solve problems based on a variety of algebra skills, including absolute value inequalities, properties of the real number system, and scientific notation.  The one page interactive instructional activity contains twenty multiple choice questions and is self checking.
Learners participate in a lesson that reviews the concept of linear functions in connection with preparation for an exam. The teacher reviews problems with the students for scaffolding. Learners practice graphing linear functions.
This activity takes you from the basics of equations of lines (slope and intercepts) to scatter plots and lines of best fit. Interpret the slope using the context of the problem and use the regression line to extrapolate values. Included in the detailed lesson plans are a warm-up activity and a link for pre-lesson review on slopes of lines. Unfortunately, the link to the end of lesson PowerPoint evaluation does not work.
Students find the slopes of linear functions. In this graphing lesson, students analyze linear equations and calculate the slope of the line. They graph a line given the slope and y-intercept.
Geometers construct a mobile or ornament using nets of three-dimensional polyhedrons. Not only do they need to compute the volume and surface area of each figure, they also earn points for creativity, neatness, and more!
In this geometry worksheet, 10th graders solve problems that are based on Algebra I and basic geometry skills.  The one page interactive worksheet contains twenty multiple choice questions and is self checking.
Adjust this lesson to fit either beginning or more advanced learners. Build a scatter plot, determine appropriate model (linear, quadratic, exponential), and then extend to evaluate the model with residuals. This problem uses real-world data and challenges one to make predications based on the model. 
Mathematicians use an inquiry method to solve linear equations. In this linear equations lesson, students practice solving equations using addition, subtraction, multiplication and division. They solve multi-step equations and equations with variables on both sides of the equal sign. Each section features a class discussion, and work sample questions. The final activity requires students to work in small groups to plan a one-day trip to France.
High schoolers are introduced to the techniques associated with interpreting functions. The vocabulary associated with this technique is reviewed, then pupils view a PowerPoint (embedded in the plan), that shows how to interpret functions. Learners then break into four groups and complete the assignments given by the teacher. Fantastic lesson!
Students explore multi-step equations. In this pre-algebra/algebra I lesson, students use the TI-nspire computer algebra system to check the steps they used to solve multi-step equations and equations with variables on both sides.
Students gather data by experimentation or observation in one of nine activities. Each group models the data they gathered, creates a display, and presents results to the class using an overhead projector.
What can a middle schooler do in 90 minutes? He can practice using the commutative, associative and distributive properties of addition and multiplication. He can also simplify expressions using the commutative, associative and distributive properties. Now that's time well spent!
