I bought these books at the Anvil sale last year. It was only recently that I really opened one and was even surprised that there was a dinosaur book among them.
I ended up reading all. I loved them. I think they're really, really, really great for grade schoolers because they make science interesting and fun. Hopefully, there'd be more issues on sale this coming December although I've just given birth then so I really don't know how I can go. Hehe.
There's also a children's book sale going on till June 6 at Robinsons Place Manila and there were so many reference books that are affordably priced. I told hubs, they're books that I know I'd read and love. I hope I can prevent myself from super shopping!!!
