Summary of Weekly Tasks [T1W4] Find details in your Google Classroom
As we are still warming up to HCF and LCM, this week's homework will focus on the preparation of one of the upcoming topics - evaluating rational numbers.
Details are already uploaded in the Google Classroom.
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:
BITE SIZE: HCF and LCM using Index Notation
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.
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.
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.
