Study Notes (p21) Questions 4 & 5 + BITE SIZE (approx 10min)

We have discussed the following in class. Here's a short clip on the explanation (again), which would be useful when you do your weekly homework

Question 4

Question 5

BITE SIZE

Read the instructions on the 1st column carefully before working on the task.

Study Notes (p18, p19, 20) - HCF and LCM

As promised during the lesson, here is the worked solution to these questions - for those who have attempted on your own.

👉 Remember: It's always useful to circle the factors that you have identified. It helps when you check your answers (especially if there's any missing factor)

HCF (p18, p19)

LCM (p20)

(A) BITESIZE

As we are still warming up to HCF and LCM, you will work on the BITE SIZE tasks (in the next post) to check on your mastery of using the INDEX NOTATION (technique) to find HCF and LCM. 

Complete by end of FRIDAY.

(B)  HW2

In preparation of one of the upcoming topics - evaluating rational numbers, you will be introduced to a new technique (single fractions). You will be handing in the hardcopy on next MON (31Jan) and a short video (≤ 2 min). You will submit the video clip in the padlet below.

Details are already uploaded in the Google Classroom. 

BITE SIZE: HCF and LCM using Index Notation (est. duration: 5 min)

HCF

 

LCM

---

These 2 clips summarises how we can find HCF and LCM of 2 or more numbers

---

Clip 1: Observe what are the factors 'circled' in each case

When we look for Highest common factor, technically, we are looking for the 'lowest' power.
For the Lowest common multiple, technically, we multiply the prime factors with the highest power.

Clip 2: Some of us learnt to find the HCF and LCM using the division method.
The clip attempts to show how these 2 methods (i.e. Long Division method and Index Notation Method) are related to each other - the same thinking behind, though the representation looks different.

Inquiry Task 3: HCF and LCM (Summary) + BITESIZE (flowchart)

You may refer to slide 4 & 5 for the generalisation and explanation

Your BITESIZE task for today is the flowchart - complete it & have it ready for discussion in the next lesson.
