Anyone have experience with the Go Math ! books ? Are these books better than the Houghton Mifflin books ?
What would be a good math book for elementary grade (grades 3-5) ? We liked Singapore Math, as well as the math mammoth worksheets. Unfortunately, Singapore math is not used in school. My child loves the The Book of Perfectly Perilous Math, I wish I knew that Math, and books of this nature.He loves Khan Academy, and works on it far above his grade level.

Thanks !
