Simplifying Exponential Expressions - Practice Sheets (4 forms) - 32 problems

(0)
This is an engaging and challenging practice on simplifying exponential expressions (the variable x is in the power indicator). The problems require good skills in using the rules of exponents (forward and backward). There are 4 different versions/forms as forms A and B have similar examples, so have the forms C and D. On each form students are given eight expressions. Students are asked to simplify them into the form a^f(x) or b. a^f(x) . This practice is much helpful for the next step - solving exponential equations. The product can be used as an independent practice or partner activity. I hope the practice worksheets give enough room for students to show their work. Answer keys are included.

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. The practice sheets provide room for students to show work. Full solutions are included.
