Das Übungsheft Grössen Mathematik 3/4

Difficulties in dealing with sizes arise in children especially when they do not have mental access to reference sizes. This complicates their orientation in everyday life, which is largely determined by the aspect of measurement. The two exercise books for grades 1/2 and 3/4 introduce sizes step by step: they build on children's experiences from speaking and play situations, compare representatives directly and indirectly, and lead through measuring with standardized sizes up to converting units of measurement. The exercise book for sizes in grades 3/4 includes: - Lengths in mm, cm, m, km, decimal numbers, and conversions - Monetary values with decimals - Times with minutes, time spans with minutes and seconds - Masses in g, kg, and t, including decimal numbers - Area measurements and volumes - Suggestions for hands-on engagement with sizes.
