KIRKUS REVIEW

Froman starts with examples of kids sharing out root beer, walnuts, and pay for a cleanup job--estimating, then changing the estimate if it turns out wrong--to demonstrate that ""when you turn division into a guessing game you do not have to remember the multiplication tables. And you do not have to guess right the first time."" But simply separating the $8.27 pay into five equal piles might require changing three leftover dollars into half-dollars, then changing the leftover half-dollar to dimes, etc. And if there are still two pennies left--well, that launches Froman into a non-mathematical discussion of all the different things you might do with remainders. As a very preliminary introduction this does make unimposing sense of division; one hopes that after a few more guessing games someone will show the same readers that it goes a lot faster if you do learn your tables.
