Greater Estimations, both by Bruce Goldstone, are two excellent books for helping
to estimate. Both books start by showing what certain amounts look like
(ie: 10 and 100 rubber duckies). The books then move on to provide
spreads with different objects that students can estimate as well as
strategies that students should try. For example:
A visually stunning book that makes teaching estimation fun and interesting. In the book, the left side of most spreads shows crisp photographs of objects in groupings of 10s, 100s, and 1000s. The right side then shows the same objects in an unidentified amount, leading readers to see how to use groupings when estimating.
SLJ promises "this well-designed book will add zing to many a math lesson."

This sequel uses the same format of eye-catching photographs and groupings of objects, but adds estimating length, weight, area, and volume. Different methods are discussed (clump counting, 'box and count') and clear explanations of how to achieve answers are given. In their review, SLJ applauded the "appealing layout that lends itself equally well to browsing or curriculum support."

pages from inside these books. In the spread, readers are invited to
estimate the number of jelly beans using clump counting or box and
count. Hints are provided. On the right, readers are
again invited to estimate the jelly beans using the suggested method of
estimating the 'first layer' (smaller image) and then estimate how many
layers there are.
