Finding the Second Derivative - Partner Activity
nikimathnikimath

Finding the Second Derivative - Partner Activity

(0)
This is a collaborative and challenging activity to practice finding first and second derivatives of simple and composite functions. The functions in this activity include polynomials, rational fractions, radicals, trig and inverse trig expressions, exponential expressions and natural logarithmic functions. Students work through 14 sections/problems(or less if preferred). Each section contains one function to be differentiated by the partners. One partner starts solving first to find the first derivative of the function, then the other partner differentiates the function that his partner has obtained to find the second derivative. In the next section, partners take turns and it goes the same way. Alternative way to use this activity: Partners can work over finding the first derivatives of the functions of two randomly chosen different sections and then to swap papers to find the second derivative of the same functions. A hint is provided in each section that gives the sum of the partners’ answers. Typed and detailed answer keys are included. I hope this activity will be stimulating and beneficial for your calculus students.

Students will need to factor the denominators factoring out a GCF and using the difference of squares formula. On the third page/slide (problems level 3) students add and subtract three rational fractions with different denominators. It is not needed for students to solve all of the problems as classwork, however they can have some of the problems as homework. The product can be used as a group activity as well (groups of 4 as each student will solve 2 problems from each page/slide). Answer keys are included.

Multiplying Polynomials - Get Points 4 Levels Activity (Build the Answer)

(0)
This is an engaging activity on multiplying polynomials. Students are given 2 pages/slides with 16 problems - 4 levels as there are 4 problems for each level. Each problem correctly solved gives points (problem of level 1 gives 1 point, level 2 problem - 1.5 points, level 3 problem - 2 points and level 4 problem - 3 points). So students try to get as many points as they can. There are 4 pages/slides included where students can build the answer of each problem using monomials given.

nikimathnikimath

Complex Zeros of Polynomials - Partner Activity

(0)
This is an engaging partner activity on complex zeros of polynomials. There are 12 sections. In each section each partner is given a polynomial (partner A is given polynomial A, and partner B is given the polynomial B). Partners have to find all the zeros of polynomials and to determine the common zeros between polynomials A and B. There are included polynomials of 3th, 4th and 5th degrees. This activity can be used as an independent practice as well. Students will search for the common roots between each two given polynomials which I think is more fun than just finding the complex zeros of a series of “random” polynomials.

Activity directions: Students begin with the problem #1, solve the problem, find the answer somewhere else on the pages ( which are five) and write “2” in the blank. Then student solve that problem (#2), search for the answer again and when find it write “3” in the next blank. Students continue in this manner until they return to the problem #1. They should solve all the problems before returning to the start point. Full typed solutions are included.
