Find teacher approved Algebra I educational resource ideas and activities
In this ration & proportion for Algebra I worksheet, students answer twenty-three word problems involving ratio and proportion.
In this Pythagorean theorem for algebra I activity, students answer 10 problems finding the missing side of a right triangle using the Pythagorean theorem.
Engage your class in a lesson that requires them to find solutions to linear equations with the help of a graphing calculator. They define the term variable and enter different linear equations on a coordinate plane. The lesson includes several examples to be used by the teacher.
Learners examine two calling plans for cell phones using the data in two different forms. They use the data and find the solution of two equations when it is graphed. The solution is found by finding the intersection of the coordinates.
Over the course of three class periods, middle schoolers design an experiment to provide learner input to administration about which rock band to invite to play at school. They practice several random sampling exercises, all well supported in this resource with reproducibles and clear directions for learners.
Middle schoolers solve a system of linear equations by graphing on the same set of axes while finding the coordinates for the point of intersection. They interpret the solution that describes a practical situation that needs to be solved.
As an introductory activity, young statisticians measure their heart rate at rest and after exercise and compute the mean and median, and create a box & whisker plot. This is followed by watching a video (that no longer seems to exist on the linked site) that introduces the relationship between exercise and one’s health. They then engage in some form of aerobic activity for two weeks and record their results in a journal. Note: A number of the links to websites no longer exist.
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.
Mathematicians use an inquiry method to solve linear equations. For this linear equations lesson, young scholars 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.
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!
