On Friday's lesson, we discussed the following:
(A) Study notes:
(1) (p4) Practice 2 - as we follow Polya's 4-step process and learn that table (as a heuristics) can be used to organise and present information clearly to solve the problem.
(2) (p3) Practice 3 - Discuss the importance of knowing the base before we compare any given percentages; else we will need to make an assumption on the base. With that, we proceed to discuss how to justify our stand mathematically when we state whether we agree with what each character says.
(3) (p6) Using Practice 1, we check our understanding when we say INCREASE a quantity by a given percentage (in particular Q1(a))
(4) (p7) Activity 2: Through the first cycle, we discussed how the "Percentage Change" informs us whether there is an increase or decrease in the percentage.
You are to attempt the 2nd cycle on your own to see how different the percentage change looks like when the process is reversed.
(B) Task in Google Classroom:
We attempt the first part of [Activity] Percentages: Point of Sale in the Google Classroom assignment.
- We went "online shopping" - identified the items from the website and filled up the spreadsheet.
- Do indicate the quantitiy for each item in column G (that I forgot to inform you in class)
Below is a sample:
Do not submit the task yet.
We have not finished the task yet, so do not submit it.
We will continue with this task on TUESDAY
