Lesson Plan 1: The X Factor - Trinomials and Algebra Tiles

Overview Procedures For Teachers Related Standardized Test Questions Materials

This lesson will teach students to factor trinomial expressions of the form x2 + bx + c. Students will use algebra tiles to identify the binomial factors and the graphing calculator to verify the result. In addition, students will identify the x-intercepts and y-intercepts of each trinomial function and explore relationships between the trinomial x2 + bx + c and its factored form
(x + m)(x + n).

Time Allotment:
One 50-minute class period

Subject Matter:

Learning Objectives:
Students will be able to:
  • Factor trinomials of the form x2 + bx + c into two binomial factors.
  • Identify the relationships that exist between b, c, m, and n when x2 + bx + c is factored as (x + m)(x + n).
