We are starting the polynomial unit in Algebra 2. I have some students who have graphing calculators. We do not have BYOD and cell phones and i-devices are not permitted in school. I have four computers in my classroom. We do have a computer lab, but there are not enough computers for all of my students to have access at the same time. Some students have access to computers at home. My district has about 55-60% of its students on free or reduced lunches. I have students of many ability levels in my classroom.
So, given that background knowledge... how would you deal with the graphing polynomials (and eventually exponential and logarithmic equations as well as rational and radical equations) with these students? Common Core says (from here):
- CCSS.Math.Content.HSF-IF.C.7a Graph linear and quadratic functions and show intercepts, maxima, and minima.
- CCSS.Math.Content.HSF-IF.C.7b Graph square root, cube root, and piecewise-defined functions, including step functions and absolute value functions.
- CCSS.Math.Content.HSF-IF.C.7c Graph polynomial functions, identifying zeros when suitable factorizations are available, and showing end behavior.
- CCSS.Math.Content.HSF-IF.C.7d (+) Graph rational functions, identifying zeros and asymptotes when suitable factorizations are available, and showing end behavior.
- CCSS.Math.Content.HSF-IF.C.7e Graph exponential and logarithmic functions, showing intercepts and end behavior, and trigonometric functions, showing period, midline, and amplitude
So, how would you do it? In the past, I have always used the graphing calculator as a part of the process. I have asked my principal for permission to use other devices in and she is thinking about it, but I am not confident I am going to get a yes answer. What would you do? Thanks for your thoughtful answers.
