High Schoolers use the TI-83 calculator to produce a sequence, explore patterns and find a linear or quadratic equation for a given pattern. They use inductive reasoning to make conjectures about patterns. They find the Y-value of a...

Have the class factor and solve trinomials of integers in the form x2 + bx + c, where b and c are positive. They relate factoring to area and then follow a specific format to factor their trinomials. Tiles are used to help them...

Learners perform factoring on the TI. In this algebra lesson, students factor equations using the FOIL method. They use the TI navigator to show each step using a visual.

Students factor trinomials. In this algebra lesson, students identify the different integers making up the trinomial and use the special pattern to factor them. They continue to model the equations and how to factor correctly.

In this algebra activity, students solve linear equations through graphing and quadratic equations through factoring. There are 4 questions dealing with systems of equations.

Students investigate the origin of the quadratic function. In this algebra lesson plan, students analyze solving an equation by completing the square. They compare the early methods as compared to our method for solving quadratics.
