Counting and Comparing Sets of Paper Pumpkins

About this lesson

In this 40-minute kindergarten lesson, partners build two rows of up to 10 paper pumpkins, match them one to one, and count to decide which row has more, fewer, or the same. Children then draw one comparison in a math journal and explain their thinking, practicing counting and comparing. You'll need paper pumpkin cutouts, journals or blank paper, crayons, chart paper, and markers.

Objective

Students will count sets of up to 10 objects and compare two sets to identify which has more, fewer, or the same number.

Materials

  • Orange and green construction paper cut into small pumpkin shapes (about 20 per pair of students)
  • Paper math journals or folded sheets of blank paper
  • Crayons
  • Chart paper
  • Markers

Hook

Gather students on the carpet and quietly place 4 paper pumpkins on one side of the chart paper and 7 on the other. Invite students to look silently for a moment, then whisper to a partner which side they think has more pumpkins and how they could check. Mention that pumpkins are often seen in autumn and at Halloween, and today we will think carefully about counting them.

Main Activity

Model how to line up two rows of pumpkins one above the other, matching each pumpkin to one in the other row, and count each row aloud slowly while touching each pumpkin. Explain that the row with pumpkins left over has more, the other has fewer, and if every pumpkin has a partner the rows are the same. Give each pair a pile of paper pumpkins. One partner builds a row of up to 10 and the other builds a second row, then they match, count, and decide together which row has more, fewer, or the same. After two or three rounds, students return to their seats and quietly draw one comparison in their math journals, drawing both rows of pumpkins, writing the number under each row, and circling the row that has more (or drawing an equal sign if the rows are the same). Play soft background music during journaling and circulate to ask each child to explain their drawing.

Pumpkin comparison: a row of 7 matched to a row of 4 with lines, 3 left over; 7 is more, 4 is fewer.
Line up two rows, match each pumpkin to a partner, and count: the row with pumpkins left over has more, and the other row has fewer.

Discussion Questions

  1. How did lining up the pumpkins help you know which row had more?
  2. What did you notice when both rows had the same number of pumpkins?
  3. If one row has 6 pumpkins and you add one more, what happens to the number?
  4. How could you make two rows that are the same if one row has more?
  5. Where else might you see groups of things you could count and compare?

Exit Ticket

Show the student two small groups of paper pumpkins (for example, 5 and 8). Ask them to count each group, point to the group with fewer, and say how they know.

Differentiation

Support: Limit sets to 5 pumpkins or fewer and provide a strip of paper with drawn boxes so students can place one pumpkin in each box, making one-to-one matching easier. Work with these students in a small group and count aloud together while touching each pumpkin.

Extension: Challenge students to compare three rows of pumpkins and order them from fewest to most, or to find how many more pumpkins one row has than the other and record that number in their journal.
