Polynomial Analysis and Calculator Practice for Algebra 2
A class practice set for Algebra 2 students that checks retention of today's lesson on polynomial zeros, intercepts, and reverse factoring using the TI-84 Plus CE, along with imaginary number operations in a+bi mode. Designed for 11th and 12th graders in regular, honors, and special education sections, it asks students to present every answer in exact form with no decimals.
“Algebra 2 Honors, Algebra 2 Regular and Special Education Students It is the eleventh week of school. The information below was taught today. Students will practice in class to see how well they retained the lesson. Use the information below to create class practice with some additional notes to bridge the gap between the lesson and any misconceptions for 11th- and 12th-grade Algebra 2 regular and special education students in periods 3, 5, 6, and 7. Present all solutions in exact form, no decimals. Topics we covered in class: · Calculator Techniques TI-84-Plus CE: · Using the calculator with to do Imaginary Numbers Operations · Use the calculator to find the following: · Zeros (polynomial functions) · X-intercepts s (polynomial functions) · Reverse Factoring s (polynomial functions) · Y-intercepts (polynomial functions)”
Teacher Guide & Tips
- Use as an in-class practice block after today's lesson, with roughly 30 to 40 minutes for the problems and a short debrief; students should work with their TI-84 Plus CE in a+bi mode.
- Discussion question: Why does a y-intercept come from evaluating the polynomial at x = 0, while the x-intercepts require solving for where the function equals zero?
- Scaffold for struggling readers: Have students first verify each keystroke sequence on a simple quadratic such as x^2 - 4 before moving to higher-degree polynomials, and provide a reference card listing the menu paths for zeros, intercepts, and the imaginary-mode setting.
- Extension for advanced students: Ask them to factor a cubic by hand, confirm its zeros on the calculator, and explain why any non-real zeros appear as complex conjugate pairs with real coefficients.
- Keep answers in exact form (for example, 3 + 2i or (-1 ± sqrt(5))/2) and check that students are not rounding to decimals when the calculator displays approximations.
