Today, students behaved quite well in the class. We smoothly moved forward in the math study. I finished word problems solving by using quadratic equations, and introduced algebraic fractions, including simplifications of fractions, multiplication and division of algebraic fractions, addition of algebraic fraction. In the simplification, the knowledge of algebraic expression factorization plays important role because without expressions in the factor form, the simplification is not able to carry out.
Here is the homework for today’s class
CH.4
14, 16, 17, 20, 21
CH.5
1, 2, 3,a, c,e,g,i; 12.a,c,e,g,i; 13.a,c,e,g,i
