Simplifying Rational Expressions/Fractions - Four Levels Practice (24 problems)

(0)
This is an engaging 4 levels practice on simplifying rational expressions. On the first page/slide (problems level 1) students are given 6 rational fractions. Students will need to factor out a GCF in the numerator and denominator and then to cancel the common factor to simplify. On the second page/slide (level 2) students will need to use the difference of squares formula and factoring out a GCF to simplify 6 rational fractions. On the third page/slide students have to factor the numerators and denominators of 6 rational fractions which are quadratic trinomials. And on fourth page/slide (problems level 4) students use the formulas for sum and difference of cubes to simplify the last 6 rational expressions. Some problems require using the polynomial identities for square of sum and square of difference. This product can be used for independent practice, extra practice, enrichment, group work and homework. The answer key is contained at the end of this document.

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. This activity can be completed individually (maximum efforts) or students can work in groups of 2 or 4. If students work in pairs there will be two problems of each level for each partner to solve (optimum pressure). If students work in groups of four there will be only one problem of each level for each member of the group (minimum pressure). This activity can also be turned to competition between groups (which group will finish first or will get maximum points). Answer keys are included.

Solving Systems with Three Variables -"Catch the Magic Fish" (Matching Game)
nikimathnikimath

Solving Systems with Three Variables -"Catch the Magic Fish" (Matching Game)

(0)
In this 12 questions - matching game, students will solve systems of linear equations with three variables by elimination and substitution or using Gaussian elimination. Cramer’s Rule is another method that students can use to solve ten of the systems. (There is one system that is consistent and its equations are dependent and one system that is inconsistent). Students find the solution to each of the given systems of equations. Their solutions are written on twelve of 13 fish. When students arrive at a correct answer, they “catch the magic fish” having this answer written on it. It is said that only one fish is not really magic, because it doesn’t fulfill wishes. Students have to find it out. The activity can be used individually, in pairs or in groups of 3 or 4. Student recording sheets and answer keys are included.

nikimathnikimath

Evaluating Polynomial Functions - Multiple - Choice St.Valentine's Day Mulitple-Choice Activity

(0)
This is a multiple-choice fun St. Valentine’s Day activity on evaluating polynomial functions. On each page/slide students are given one polynomial to evaluate for a given value of x. Students are asked to use substitution or synthetic division or both methods. There is given a picture of heart and faces of a girl and a boy inside the heart, students also have four answer choices and love words corresponding to each answer choice. Students have to use their answer to find what love words has the boy said to the girl on St. Valentine’s Day. The pages/slides with problems are eight. Students can draw a shape of a heart to mark their answer choice in each slide. The polynomials included are of 3th, 4th, 5th, 6th and 8th degree, the number of terms are from 4 to 6. This activity can be completed individually or students can work in pairs (partner A will evaluate the polynomial using substitution and partner B will evaluate the same polynomial using synthetic division, then partners compare their answers and choose the correct answer choice; on the next page/slide partner A will use synthetic division and partner B will use substitution to solve the problem. Thus partners will practice both methods and will enjoy this activity together. I think this activity can be used in all days of school year. The answer key is given at the end of this document.
