Grade 1-4.The basics of addition and subtraction are presented in two-page
explanations and demonstrations. Each book contains a detailed table of
contents, a one-page index, and a table of subtraction and addition terms.
Problems and examples are explained and profusely illustrated with pen-and-
ink drawings. Unfortunately, there are no practice problems. These books
would serve as quick references or beginning guides for teaching math, but
it's unlikely that children will pick them up. They might be a reasonable
purchase for libraries that have a home-school population.
