Factoring Trinomials (Day 4)

50 Minute Class, Algebra 1, Curriculum

Learning Goal: Develop conceptual and procedural fluency with solving quadratics by factoring.




  • Common Core
    • HSA.APR.B.3 – Identify zeros of polynomials when suitable factorizations are available, and use the zeros to construct a rough graph of the function defined by the polynomial.
    • HSA.SSE.B.3.A – Factor a quadratic expression to reveal the zeros of the function it defines.
  • TEKS
    • A.7(B) – describe the relationship between the linear factors of quadratic expressions and the zeros of their associated quadratic functions
    • A.8(A) – solve quadratic equations having real solutions by factoring, taking square roots, completing the square, and applying the quadratic formula
    • A.10(E) – factor, if possible, trinomials with real factors in the form ax² + bx + c, including perfect square trinomials of degree two

    1. Thanks for the question! Spiraling Practice is just a practice handout with concepts that we’ve already learned during the year. The goal is to keep students fresh with previous concepts while we move on to new concepts. In addition, I use spiraling to work on common errors I found in previous units. I also like to use spiraling to help prepare students for retakes and upcoming district exams.

      Usually, spiraling assignments are done either during independent work time or free group time toward the end of class. I usually don’t teach through the handouts unless questions arise while students are working on them.

      Hope that helps!
