In this algebra lesson, students define algebraic terms and rewrite them using math symbols. There are 10 problems drawing correlations to geometry as well as algebra.
This lesson is all about systems of equations and their graphs. Algebra learners create and solve systems of equation using tables and graphing. They identify the point of intersection of a system of equation, and discover what the solutions are when the lines are parallel or are the same line. 
In this  activity that integrates chemistry and algebra, learners solve systems of equations using matrices. The coefficients required to make chemical reaction balanced need to be determined. 
Tap into the competitive nature of teenagers as your class practices setting up and solving rational equations. This activity starts with a specific ratio of games won to games played, then asks how many more games must be played to improve that record. Stretch problems include explaining why (or why not) the winning percentage could reach 100% and working with a winning streak followed by a losing streak. Skills incorporated in this brief activity include changing percents to decimals, cross products, translating verbal problems to algebraic equations or inequalities.
How can learners use algebra to solve a geometry problem? Help learners create an equation that shows the relationship between the number of sides of a polygon and the sum of the interior angles. Young scholars are asked to divide the quadrilateral found in the resource into two triangles. Then recognize that the sum of interior angles for each triangle drawn is 180 degree and the sum of the interior angles for the quadrilateral is 360 degrees. The second polygon is a pentagon, using the same method, number crunchers verify that the sum of the angles is 540 degrees. It is now up to your algebra learners to describe the relationship of the number of sides and the sum of the interior angles with an equation.
Challenge algebra learners to use the difference of cubes to solve this problem. Once your charges have taken out the factor (a - b), combined the like terms and set them equal to zero, the problem becomes a factorable quadratic equation. Some pupils may use the quadratic formula to solve. Both solutions are illustrated in the resource.
Algebra learners are to make sense of two different-sized sand trucks and the number of trips each truck makes. The resource lists four different expressions based on the size of each truck and the number of deliveries the trucks make. Students are to state what quantity each expression represents.
Students use a spreadsheet to investigate data. In this algebra lesson plan, students collect and graph data on a coordinate plane. They explain properties of a linear equation both algebraically and orally.
Students describe graphically, algebraically and verbally real-world phenomena as functions; identify the independent and the dependent variable. They translate among graphic, algebraic, and verbal representations of relations and graph relations and functions and find the zeros of functions. Finally, students write and interpret an equation of a curve (linear) which models a set of data.
Students explore functions using real world application. In this algebra lesson, students play a game as they apply concepts of function. They graph their findings and discuss it with the class.
Students estimate and calculate the distance of a shape. In this algebra lesson, students differentiate between a horizontal distance and it's reflected image. They measure the reflection and the point starting at the eye of the observer.
Students collect data and create a graph. In this algebra lesson, students describe functions graphically, algebraically and verbally. They identify functions as being independent and dependent using variables.
Students secure information online using cryptography. In this algebra lesson, students use RSA technology to encrypt information on the internet. They use modular reduction of natural numbers to understand prime number theory.
Students plot the graphs of systems of equations and solve the solution to the equations algebraically. In groups, they investigate the solution of two conic sections. Students graph equations and find the points of intersection.
Students rewrite word problems using symbols. In this algebra activity, students rewrite equations graphically, algebraically and verbally. They relate the concepts to the real world.
Students create graphic, algebraic and verbal ideas of functions. In this algebra lesson, students graph functions and identify the zeros of the functions. They find the domain and range and classify functions as relation or not.
Students explore linear equation suing real life scenarios. In this algebra lesson, students find the slope and intercept of a line. They create table of values to plot their graph and draw conclusions.
Students solve problems using matrices. In this algebra lesson plan, students add, subtract and multiply matrices. They use the graphing calculator to simplify and graph linear equations.
Young scholars play a memory game as they explore reasoning. In this algebra lesson, students identify concepts using pictures and words. They model real life scenarios using hands on manipulatives.
Learners count from 0-99 using the binary number system. For this algebra lesson, students problem solve by working with faulty circuits and applying their knowledge f Binary Numbers. They work in team to create a solution.
