Quantity Comparison

The ability to compare quantities and numbers using language like 'more than', 'fewer than', 'less than', 'equal to', and eventually mathematical symbols (>, <, =). Includes comparing both concrete sets of objects and abstract numbers.

How it's taught

japan_elementary

Hands-on exploration with compasses and circular objects, progressing to formal properties and calculations. Students draw circles, measure radii and diameters, discover the relationship between circumference and diameter empirically, then formalize understanding of pi.

Materials: Compasses, rulers, circular objects for measuring, string for measuring circumference, grid paper, protractors
