Look what the Tooth Fairy brought in



After Ann recommended the book, The Mystery of the Periodic Table, to me, I found that quite a number of pages could be read on Googlebooks...Sean read some pages and said he'd like to have the book. I ordered the book on September 11 from www.bookdepository.com and it arrived yesterday. So convenient, thanks to Slim for the site recommendation.

Between the time I ordered the book and its arrival yesterday, Sean bugged me about it constantly. He really likes the book. Not a bad exchange for 1 lost tooth eh?

Hey, I have this book already! It's really quite fun and well written. I'm sure Sean will enjoy it. The other thing is that Top 10 list of Amazing chemical Reactions you sent me some time ago. Very super duper! We keep digging it out every now and then cos of the glorious fizz-and-bangs!

I forgot about that Top 10 list! Thanks :) I should put that as a permanent link on the side of the blog.

Are you still using Noeo Science?

Alcovelet said...

Noooeoe (Corny lah!) Was telling Ailei, the biology part was so boring, he just didn't want to continue. But the chemistry bit was great, and physics too!

He's reading through a lot of the Horrible Science books and any mags I can find, and the DK picture books - Robert Winston's It's Elementary is super!!. There's a surprising number of facts and experiments they can try on their own too, hehe.

Oh, thanks for sharing the link to Book Depository, what a great site!! I can't believe any online bookstore can offer free delivery at those prices. Thanks!!

Lilian said...

Yeah, I don't think it's the cheapest store, but the good thing is you can just order 1 book at a time, and not buy a bundle just to save on shipping. I ordered 4 more comics the next day and they arrived in 4 different envelopes!

Lilian said...

Unfortunately though, they don't deliver to Russia :( :( :(

monlim said...

The prices are pretty good, Beast Quest for example, is cheaper here than at Borders with the discount coupon! And there are some books that Lesley-Anne likes that you can't find in the bookstores here. Great find!

Lilian said...

Ooh, that's great. The comic I bought for US$9 incl delivery is selling at Kinokuniya for S$22 :) I doubt Borders even carries it.

When we gave Stephen $5 for his first lost tooth, he was thrilled because one of his classmates only got $3. O_o Of course, Marv wanted to give him $1 but there's been inflation since our days!

Lilian said...

Whaaaaaa....t??? $5???? I was actually thinking of a 50-cent coin or at most a $1 coin hehehe...

Anonymous said...

oh my, my hb left a $10note for the 1st time, as that was what he had in his wallet, from then on....it has been $10 per tooth...

Should reduce the amt and let T know due to current economic crisis, the fairy oso got no money....

Wow, the online book store is so efficient. I hope you can help me with this math question as you are good with the model method.

Can the following math question be solved by the model method? If yes, can you please let me know how to solve it by using the model method?

Questions:
There are 50 heads and 79 legs of 2 legged and 1 legged birds. How many 2 legged and 1 legged birds are there?

Thanks in advance!

Lilian said...

Sorrylah, I'm not the one who's good at Models, my friend Monica is. Click on Monlim, one of the commenters here and you'll find a link to her blog :)

My son does this in a very strange way but he says his teacher marks it right.

Least possible number of legs --> 50
Number of extra legs for every 2-legged bird --> 2 - 1 = 1
Number of 2-legged birds --> 79 - 50 = 29
Number of 1-legged birds --> 50 - 29 = 21

**************

I only know algebra:

Let x be number of 1-legged birds
and y be number of 2-legged birds

x + y = 50 -----(1)
x + 2y = 79 ----(2)

(2) - (1)
y = 29 ----(3)

Substitute (3) into (1)
x = 21

******************

Sorry can't help with Models. In PSLE, it's perfectly fine to use algebra, just in case you're not aware.

Thank you Lilian for your reply. I was not aware that algebra is allowed in PSLE. I have asked Monica in her blog. Hope that she will answer like you did. Thanks again!
