There is a companion worksheet for this activity. The Desmos interactive will calculate the slope of the line connecting the two points, as well as the graph of the line itself. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. They can also use the provided sliders to input the values. This activity is designed for Algebra 2 students who are learning about polynomial functions. plot points, visualize algebraic equations, add sliders, animate graphs, and more. Students input the values for the two coordinates. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. But the amazing math teachers out there are making entire COLLECTIONS of self-checking Desmos Activity Builders! So I thought I would add them here. The Desmos activity includes the slope formula equation. I have created a set of sample assessments and self-checking Desmos for you to assign and copy/edit. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. However, to edit self-checking assessments, you will need to use Desmos Computation Layer (CL), which is the coding that goes on behind the screens! I have more resources about learning CL here. Explore math with our beautiful, free online graphing calculator. Their first line of attack in finding zeroes is to use graphing technology and then they know they can use synthetic division and the quadratic formula if they can't get the whole picture just from their calculator.įollowing polynomial functions with rational functions let them further see the value of being able to find zeroes of polynomials as the zeroes of the numerator and denominator are used to find holes, x-intercepts, and vertical asymptotes.Here is my Desmos Webinar about creating assessments and self-checking Desmos Activity Builders.Īnyone can make a code for an existing activity to give to their students. The graph curves up from left to right touching the x-axis at (negative two, zero) before curving down. Key features include: x and y intercepts, leading coefficients, and degree of the. They get how to determine end behavior and they get what effect the multiplicity of each zero will have on the graph. A polynomial is graphed on an x y coordinate plane. Use Key Features of factored polynomial graphs to sketch the polynomial. My students really seem to get that the number of zeroes a polynomial function has is determined by its degree. The degree of a polynomial function affects the. 5-1 Activity: Investigating end behavior and turning points of polynomials. With the graphing technology available to students, I feel like things like Descartes Rule of Signs and the like are just outdated and unnecessarily confuse what should be a simple concept like the Fundamental Theorem of Algebra. Explore math with our beautiful, free online graphing calculator. I REALLY like how I did this unit this year. So there's a quick and dirty rundown of what's been going on in my class the last couple of weeks. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. Students worked in pairs to match up all of the cards.ĭay 4 was this asymptotes sudoku puzzle, also from Teachers Pay Teachers. How to graph polynomial function with the use of Desmos. Rational functions day 3 was this matching activity I found on Teachers Pay Teachers. Our second day with rational functions found us doing this activity I got from Rebecka Peterson.
