Students will compare objects based on their size.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

(5 minutes)
  • 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.
(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.
(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.
