When i was working on mathematics with my son i saw a very interesting book he had called mental math problems, the problems mentioned in this book were so simple and a good exercise for children of 6th grade math.
My son started working on that book and i found it a good book for him. He found it difficult in the initial stages but once he got the hold of the book, he went on doing it in that way that he knew these problems before itself. I was very happy with his efforts. He had many topics on addition, multiplications and other mathematics operations. I found the book very useful.
He had mean mode median range worksheet in it also, he worked it out as well amazing efforts from my son.
