Today, students studied the new contents in solving quadratic equations with the coefficient of quadratic term not equal to 1. It is definitely harder than the case as the coefficient of quadratic term is 1. Factorization is the one of … Continue reading →

In the class, students reviewed the parallel lines and transversal system, and the properties and relations of all angles in the system. By studying a couple of examples, students learned to use the knowledge to solve the angle problems in … Continue reading →

Today, I started the new chapter, quadratic equations, basic nonlinear, but very important, expressions and equations. I introduced the basic concepts of quadratic expression and equations, and the methods to solve the quadratic equations with coefficient of quadratic term being … Continue reading →

Today, students continued to study the linear inequality, solving one variable inequality, three ways to represent inequality solution, inequality notation, interval notation, and number line; For two-variable inequality, graphing is used to present the solutions because the solution is zone … Continue reading →

Today, students finished congruence and similarity study and started to work on parallel lines and transversal. In the similarity, one of the transformation, the enlargement, was introduced. The center of enlargement and scale factor are two key information to determine … Continue reading →

Today, we resumed the class and students started to study inequality, the basic rules, and the application of those rules in the number comparisons and solving linear inequalities.Homework for today’s class:P.259, 9.1.1, 9.1.2, 9.1.3, 9.1.5P.264, 9.2.1, 9.2.2, 9.2.3, 9.2.4

Today, we had the first class in 2020. Students continued to work on “congruence and similarity”, the transformations like translation, rotation, and combinations. In similarity, students learned relations between object and image in terms of the ratio of corresponding sides … Continue reading →

In today’s class, students reviewed the method of writing line equation, the slope-point, furthermore, writing line equation using two given points; In addition, students learned the different line form, slope-intercept form and conversion between standard form and slope-intercept form. In … Continue reading →

Today was the last class of 2019 in NCLS, as well as our math class. In today’s class, students continued to study word problems in fraction section. In order to help students to overcome the barriers in solving word problems, … Continue reading →

Today, students continued to study the fractional expression operation, addition and subtraction, or called representing fraction expression in single fraction form, primarily the skill of finding least common multiple in algebraic expression way. The knowledge of simplification of fraction expressions … Continue reading →
