It is such a pleasure to work with this group! Each of the 10 students did a fantastic job today in contribution to the class discussion and demonstration of your work on the whiteboard!

First of all, thanks to Kevin, Irene, Julia, Marina, Angus, Austin, and Danielle for bringing your corrections to the pretest! I will continue to check the corrections next week:)

Congratulations to Julia, Ellen for getting all 15 problems right on the homework, followed by Emma (14/15), Irene and Danielle (13/15)! Keep up the good work, everyone! Practice makes perfect 🙂

I also appreciate how Sarah and Ellen explained the examples in class (loud, and confident), and how Marina and Julia reached out for questions. I firmly believe that this class of students have a great potential to learn and I look forward to seeing all your progress week by week!

Lesson Review:

Simple Interest: A = P (1+r% * t)

Compound Interest: A = P (1+r%/n) ^nt

Percent of change = (new value – old value )/old value * 100%

*for problems such as “how many percents is A greater/less than B”, we always choose B (the one after the word “than”) as the benchmark (what you compare with), and put b into the denominator.

Homework:

1) Finish Pretest Corrections if you have not finished all of them (use different colors, show the steps/procedures)

2) Corrections to Chapter 1 Exercises (use different colors, show the steps/procedures)

2) Finish the rest part of Chapter 2 Exercises (Page 20-22)

* If you have an incoming SAT test, please feel free to let me know. I will give you extra support (some sample test papers, some tips to prepare the exams and so on).

Last but not least, many thanks to Michelle, my great TA, for checking all the homework and explain the problems!

See you next Sunday!
