A lot of effort goes in generating printable maths lessons for children of all ages. Equations have been a source of great confusion for most children and these can be easily learnt by solving the worksheet pages. The worksheets can also be prepared according to the needs of the child. The customised work papers can have a limited number of problems, a predicted font size and a topic of interest.
Books _ Among the dozen or so math word_problem books of note published in the past decade, one, written by Mary Jane Sterling, from a well_known, popular brand of information books, which I'm unable to name here, stands out. The publisher has put a decent chunk of the book online at books.Google.com (go to books.google.com and search for sterling word problems).
