Math in Focus: Singapore Math: Student Edition, Book B Grade 3 2009

book with good condition as promised

Thanks

I like it..

As expected.

There is blood on the back cover. So disgusting. I threw it in the trash. Will never buy from this seller again.

Singapore math is all the rage at the present moment. The efficacy of this method is still to be evidenced. No current research available. Another method to teach children basic math.
