Students will be able to develop an understanding of the fractions 1/2, 1/3, and 1/4 compared to a whole.
Introduction (5 minutes)
- Tell students that they will be reviewing the fractions of 1/2, 1/3, and 1/4 through physical representation.
- Ask students what they think of when asked to describe 1/2, 1/3, and 1/4 in their own words.
Explicit Instruction/Teacher Modeling (10 minutes)
- Take out your four differently colored pieces of construction paper.
- Label the first piece of construction paper "1."
- Fold the second paper in half, and cut on the folded line. Label each of these halves "1/2."
- Fold your third paper into thirds, cut along the folded lines, and label each third "1/3."
- Take your last piece of paper and fold it into fourths. Cut along the folded lines and label each quarter "1/4."
Guided Practice/Interactive Modeling (5 minutes)
- Display these papers somewhere all your students will be able to see them.
- Ask students if they have any questions.
Independent Working Time (20 minutes)
- Pass out four pieces of construction paper to each student.
- Have students repeat your steps to create a whole, two halves, three thirds, and four fourths.
- Students will be able see that two halves, three thirds, and four fourths all make up a whole by placing the different fraction pieces on top of the base paper (the whole).
- Have students play around with the paper pieces to see what makes up a whole. For example: 1/2, 1/4 and 1/4 all make one whole.
- Give students the Fractions worksheet to complete.
- Enrichment: Have students use another color of construction paper to make up another fraction (such as 1/6) for this activity.
- Support: Help students with paper folding to make accurate fractions for this activity.
Assessment (5 minutes)
- Students will be assessed by the correctness of their worksheet.
Review and Closing (5 minutes)
- Have students share what different fractions can make up a whole and have them physically show it with their paper fraction pieces.
