This medium worksheet steps up from tracing to deeper recall and matching. Part A presents nine fill-in-the-blanks covering ideas like 'one half means there are two equal parts,' 'four fourths equal one whole shape,' that a line through the center of a circle makes two halves, and that a square can be cut into fourths using two lines. Part B finishes with a four-pair matching task that links Half, Fourth, Whole, and Equal parts to their definitions: 2 equal pieces, 4 equal pieces, all parts together, and same-size pieces. The combined format helps students lock the vocabulary to clear visual meanings.
