Arc Length and Area of a Sector - Practice A & B

(0)
These are two forms of engaging practice on arc length and area of a sector. The forms are similar and each form contains 7 problems graduated in difficulty. The first problem is finding the arc length and sector area of four pictured sectors as the measure of the central angle and the radius are given. The second problem is calculating the area of a pictured segment. The next five problems are text problems. For problem 3, students have to find the length of an arc given its angle measure and the diameter of the circle. Problem 4 is finding the diameter of a circle given an arc length and its central angle. For problem 5 given are the radius and an arc length, students have to find the sector area. Problem 6: given the radius and the sector area, student will find the central angle and the exact and approximate values of the arc length. And problem 7: given the arc length and sector area, students have to evaluate the diameter and circumference of the circle.

Operations on Functions- Group Activity 4 members/Independent Practice 4 forms

(0)
In this engaging and collaborative group activity (for groups of four), students will practice operations on functions (adding, subtracting, multiplying and dividing). There are 7 sections as each section has four subsections A, B, C and D (a total of 112 problems). In each subsection are given different pairs of functions as each partner has to perform adding, subtracting, multiplying or dividing. The subsections are four so each partner to go through the fourth different operations on functions. In section 1 the given functions f(x) and g(x) are both linear. In section 2 f(x) is a quadratic binomial and g(x) is a linear function. Section 3: f(x) and g(x) are both quadratic binomials. Section 4: f(x) or g(x) is a cubic binomial and g(x) or f(x) is a quadratic trinomial. Section 5: f(x) and g(x) are both radical functions. Section 6: f and g are rational functions. Section 7: in subsections A and B f and g are both exponential functions and in subsections C and D f and g are both trigonometric functions. The teacher can choose on which sections the students to work on. This group activity may turn into competition between groups. ☞The resource can be also used as four different forms of independent practice. Answer keys are included.

Trigonometric Equations - Group Activity/Practice (48 equations + keys)

(0)
These are 12 cards for partners – a total of 48 trigonometric equations. Students will practice solving basic trig equations, equations with multiple angles and equations of quadratic type. They will need to use factoring method and the quadratic formula, the fundamental and double-angle identities. There is one trig equation involving a parameter on each card.

Factoring by Grouping - Partner Activity (Solving a problem in 2 different ways)

(0)
Students will factor polynomials with four terms using the factor by grouping method in this collaborative partner activity. It consists of 12 sections as in each section students are given one and the same problem. Partner A is instructed to group the first two terms together and then to group the last two terms together, while Partner B is instructed to group the first and third terms together and then to group the second and forth terms together. Thus partners see that factoring by grouping problems can be approached at least in two different ways. In the next section students are given the next problem as this time Partner A is instructed to group the first and third terms together and then to group the second and forth terms together and Partner B is instructed to group the first two terms together and then to group the last two terms together. Then, in the same manner as in section 1, Partner A groups the first two terms together and …etc. I hope your students will love this activity and find it enjoyable and helpful.
