Measurement units can easily turn into obstacles for many students, as learning specific acronyms, and understanding the difference between the measurement units such as length, capacity or weight. Thanks to this activity book, children can approach not only units of measurement, but also equivalences, that is, the calculations that allow us to make comparisons. Children can face the concepts of the book through games and exercises that become progressively more difficult, set in the world of dinosaurs. By playing with the long neck of a brontosaurus, with the different weights of the triceratops and the pterodactyls, and comparing them with modern day objects and settings, children will easily assimilate the concepts presented in the book.
