Comparing Bigger and Smaller
Students will compare objects based on their size.
- Draw circles of two different sizes on the board. Ask, “Which is bigger?”
- Have students turn and talk to a partner about which circle is bigger.
Explicit Instruction/Teacher Modeling(10 minutes)
- Explain that the bigger circle is bigger because it takes up more space. Tell the class that they compared objects by deciding which was bigger and which was smaller.
- Say, “Big and small are opposites. When you compare objects to decide which is bigger or smaller, you think about how much space the objects take up.”
- Draw two stars of different sizes. Have students share which star they think is smaller. Then draw four additional stars. Ask students which star they think is the biggest and which star they think is the smallest.
Guided Practice/Interactive Modeling(10 minutes)
- Hand out paper to students. Tell them that they should draw two objects of different sizes on the paper.
- When they are done, have students trade their papers with a partner and circle the biggest object on the page.
Independent Working Time(10 minutes)
- Tell students that they are now going to practice comparing objects.
- Hand out the Animals Big and Small and Trees Big and Small worksheets. Have students complete the worksheets independently.
Enrichment: Have students draw groups of objects and put them in order from smallest to largest.
Support: Have students work with a partner to complete the worksheet.
Assess students’ understanding by having them share their answers to the worksheets out loud. Reinforce the concepts of bigger, smaller, and comparison.
