Algebra I Lesson Plans

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. 

Ninth graders investigate polynomial multiplication.  In this Algebra I lesson, 9th graders use a TI-nspire handheld and applications to explore multiplication of number, binomials, a binomial by a polynomial, and polynomials.  The dynamic nature of the software provides students with immediate feedback.

Students examine linear and non-linear functions.  In this Algebra I or II lesson, students investigate the realtionship between numerical (table), graphic, and symbolic representation.  The use of a graphing calculator is needed to complete the lesson.

Students explore polynomial graphs.  In this Algebra I or II lesson, students investigate the end behavior and the maximum number of turns of the graph of a polynomial.  Students examine the relationship between the leading coefficient and degree of the polynomial and the graph of the polynomial. 

Students decompose a larger geometric shape into smaller parts.  In this Algebra I/Geometry lesson, students examine the Orion spacecraft to determine its area.  Students apply the area formulas for the various geometric shapes found in the decomposition model to estimate the area of the spacecraft.

Ninth graders investigate linear functions and systems of linear equations.  In this Algebra I lesson, 9th graders compete against each other by solving problems posed by their opponent.  The topics covered in this “battle” include finding the equation of a line, manipulating the calculator’s window, and finding the intersection of two linear equations. 

Ninth graders track the hit count on their favorite web sites.  In this Algebra I lesson plan, 9th graders record the number of hits on their favorite web site for twenty days.  Students explore the data to determine if the relation defines a function and use the data to make predictions.  Students use Excel to produce a chart of their data and create a PowerPoint presentation of their recorded data. 

Ninth graders explore absolute value functions.  In this Algebra I lesson, 9th graders examine data by comparing individual data points to the mean by finding the differrence and the distance from the mean.  Students investigate the absolute value function in the y=register to model the relationship between the distances and the differences. 

Students investigate steganography, the science of writing hidden messages.  In this Algebra I/Algebra II lesson, students use technology to create a simple example of a hidden message inside a digital picture and then decode a partner’s message. 

Ninth graders explore binomial multiplication.  In this Algebra I lesson, 9th graders investigate binomial multiplication through the use of technology.  Using  a graphing calculator, students enter the binomial expression into Y1, multiply the binomials and enter that result into Y2, and combine like terms and enter that result into Y3 to verify.
