«Come una y cuenta veinte» is the illustrated math riddle book by Greg Tang, published by Editorial Everest in hardcover (40 pages, in Spanish).
A book that poses visual riddles in verse: you have to count grouped items, like bunches of grapes, and add using shortcuts instead of counting one by one. The verses work as clues to find the answer before others. A playful method to speed up mental arithmetic.
Part of the Rascacielos collection from Editorial Everest, with illustrations by Harry Briggs and translation by María Luisa Balseiro. Recommended reading age: from 6 years.
For children from 6 years who are starting to add and looking for a first playful approach to mathematics.
