**igcse math grade 10**

our quick look at how to calculate with and represent continuous data will have an end this week, with a mini-test on wednesday

**or**friday. the homework for the week is chapter 17 review sets. this is really not very difficult - keep focused and perform well! those who want to do the retest on wednesday are warmly invited to leave your name in the post below.**ib math sl grade 11**

much fun is guaranteed in our next content area, within the algebra spectrum: sequences and series! homework will be 2A,B,C and D1! it seems a lot, but you don't have to do everything; you do have to know how to do everything!

**ib math sl grade 12**

no homework this week, to give you time to work on the internal assessment. so it's basically work in class involving all things statistics. knowing this class a little, this part will not be complicated at all. your ti-calculators will be very important these next weeks.

we start with an internal assessment part (conclusion/evaluation) for a grade, on monday (today), in class. then: work & energy, and efficiency. next week, on thursday, we should have our first big test, in mechanics.

extra info on internal assessment, and a prompt for one. in astrophysics: cepheid variables, magnitudes & stellar evolution. then, it's cosmology time!

ReplyDeleteMr. Goncalves,

It is concerning the Maths Portfolio Task Type II (IA). Should the data on the times of sunrises/sunsets over a specific city be absolutely accurate? I am examining the data on the times over a period of 52 weeks in one year. This would require me to calculate the average time of sunrises/sunsets for a week for 52 weeks! It would consume time and cause several manual errors. Is it not better to just take the times of sunrises/sunsets for every last week? Please let me know of any suggestions or improvements. It would be much obliged.

Other than that, I hope you are having a pleasant evening.

Kind regards,

Stephanie P.

Hi Stephanie, saw this only today.

ReplyDeleteFor the real data, once a week is a good compromise, for sure, ok?

The average time of sunrise/sunset can be estimated using just the highest and lowest values...

have a nice afternoon!

ReplyDeleteMr. Goncalves,

Two questions concerning, again, the Maths Portfolio Task Type II (IA). Do you mind telling me how I can transfer the functions in Autograph onto a Word/Excel Document? And, how is it possible to shade in Autograph? Please let me know soon. It would be much appreciated.

Other than that, I hope you are having a pleasant weekend.

Kind regards,

Stephanie P.
