Ana bought a cabbage and her mother cut it into two equal halves. She used one half for a beef dish for dinner and the other half for a vegetable dish the next day. The lesson teaches that when a whole is divided into two equal parts, each part is one-half, and when divided into four equal parts, each part is one-fourth. Students are asked to name fractions such as one-half and one-fourth.
