If you know the addition and multiplication tables cold and is in at the least fifth grade, then start with Life of Fred: Fractions.  Your child will learn why it is important not to run while carrying an 18" knife.

 

     There is no hurry!  It would be a mistake to push kids into Life of Fred: Fractions before they are developmentally ready.

 

     Students of normal academic ability and drive who begin Life of Fred: Fractions even in the 7th grade have a decent chance of starting college calculus (Life of Fred: Calculus) before the end of their high school years.
