Rational Numbers and Equations

Module 1 :  Fractions and Percents

In this module students will review addition and subtraction of fractions both symbolically and with graphs/tables.  They also compute percentages,  products and quotients of fractions symbolically and with graphs/tables.  There are several lessons where linked to LearnZillion.  Please go to that website and create an account or you can go to each and sign in as a guest to access the lesson.

Module 2 : Rational Expressions and Equations

In this module students make the connection between calculations on fractions and simplifying rational expressions.   They use the arithmetic model as a means of simplifying, as well as adding, subtracting, multiplying and dividing rational expressions.   In lesson 4, they solve rational equations as well as solve rate problems. There are several lessons where linked to LearnZillion.  Please go to that website and create an account or you can go to each and sign in as a guest to access the lesson.

Module 3:  Solve Rational Inequalities and Graph Rational Functions

In this module, students evaluate rational expressions and solve rational inequalities.  They graph rational functions,by first finding asymptotes and the zeros of the function.
