From past experience tutoring JC and IB students: Usually schools recommend a particular graphing calculator to use. Then, in notes or class instructions, it’ll be based on that particular calculator. If any student chooses an allowed calculator, but different from that chosen by school, that student would likely have to learn to use it himself/herself.

Using app on smartphone is not feasible, as smartphones are not be allowed in exams.
Hope this helps.

Usually, if the question says a dimension is rounded to 0.01, the upper and lower bounds are found by taking that given dimension +/- 0.01/2 = 0.005.


So, in this case, they are 0.03 + 0.005 = 0.035 and 0.03 - 0.005 = 0.025

Hope this helps.

in my opinion and experience, i think Lianhua Primary is better than Bukit View Primary. Generally, teachers are very caring in Lianhua.

slmkhoo: I agree that what I said about wasting time may not be true of "all" kids. Unfortunately, the kids I described aren’t mine. They are what I see in classes (top or last; any level). Very few in any class will take up a book to read or do something useful, like completing to-be-completed assigned homework.

I agree regarding creating a habit of studies or learning. It’ll take anyone far beyond learning in schools.

It’s best that students are trained to spend a reasonable amount of time each day after school (since they attend schools) to revise their day’s lessons. But, sadly, this is not the case among kids today. They don’t treasure time at all – give them 5 minutes, they waste it; give them half an hour, they waste it; give them 1.5 hours, they waste it.

Estéema:

Agree with you that parents have to set clear rules & limits & enforce them well.

We cannot pass on the responsibilities to school, altho we hope the educators can hv a set of rules to limit usage & similarly enforce. Not suggesting we go back to no hp or technology days.

DH is more lax with kids. I'll watch their time spent, but when time to put away (e.g. By 9.30pm DH suppose to be the one keeping), so DC will put on the table. Minutes later when DH doing his work, DC quietly sneak away & use again. I was watching, but u know, as mums, we multi-task. I can be packing up my stuff, I'll notice every small movements. I saw DH eyes was turning towards DC but he didn't issue any warning. After a couple of chats abt enforcement, DH now hv a hang abt how I am firm & quick in arresting a bad habit before kids get a leeway.

We put kids work areas in a quiet corner of living area (within clear sight) - we call it the study corner. Charging stations all at living room. No data plan. Individual SIM card to be topped up on regular basis. All hp kept out of sight by 9.30pm & collected next morning fr 6am. Allow wifi access only when hmwk need research & googling for info (usually I delay this gratification - wait for dad's wifi when he returns u can go online so meantime do written work, planning, studying work. Once in a while, when it's closing deadline, I open up my wifi for early completion of hmwk.

It's alr not easy btwn parents to work parenting rules out. Can we expect this fr sch? Teachers hv to teach & guide our kids academically, and we're imposing time on them to police our kids. We'll hope most parents hv well behaved kids to minimize need for lesson-time to be wasted on lecturing on 自我控制. So, as parents, we guide at home & work with school for special assembly talks or workshops on device usage. I know not all schools hv strong PSG nor there be many parents having spare hours.

Still good to collaborate so tt young ones hv good rules & limits to work by.

I find Esteema's responses (above and earlier) very useful, and will like to share them with other parents not here.
Here's something to share:
I know of a primary school that has recently announced that kids are not allowed the use of mobile devices whenever they're on the school premises. At any time, and in emergencies, the kids are told they have a telephone to use in the school's General Office. And yes, I've seen kids lining up to use that phone during recess or at dismissal. The kids are told that should mobile phones be seen in school, the phones would be confiscated and only their parents can retrieve them from the school.

if i’m not wrong, NYGH is affliated to HCI.
