Happy Mathematics – Year Four

Like in previous volumes in the series, Happy Mathematics- Fourth Grade teaches mathematics in a fun and narrative way, which helps children approach the topic with calmness and curiosity.

Along with Cloud, Mistral, Mitzy, Mizar and Balù, the students participate in activities which require them to classify, compose and decompose numbers, compare them, order them, use different calculation strategies, recognize the properties of operations, solve riddles and word problems in everyday contexts, work with fractions, decimal numbers, units of measurement, and geometric shapes.  Each situation presented favours the acquisition of the skills necessary to analyze, understand and make the correct choices, as well as the translation of skills into mathematical skills.

Aimed at primary school teachers, this volume can also be used at home to practice
