Teach Background Knowledge TemplateWrite Student-Facing Language Objectives Reference
  • Gather students on the rug and ask them to show you a number of fingers less than 10.
  • Ask students whether or not it is possible for just one student to show 44 fingers.
  • Work together as a class to show 44 fingers. Let students figure out that four students should stand at the front of the class, each showing 10 fingers, with a fifth student showing four fingers.
  • Think aloud, "I see four sets of 10 fingers, and four extra fingers. Four sets of 10, plus four, is 44." Point to the raised fingers as you say, "Let's count by tens first. Ten, 20, 30, 40, 41, 42, 43, 44."
  • Model showing and counting a few other two-digit numbers as a class.
