Sign in to track this

What mastery looks like

  • Draw a picture or use objects to represent a simple real-world situation involving counting or comparing
  • Write or dictate a number sentence to describe a real-world situation (e.g. 'I had 5 apples and ate 2')
  • Use the model to answer a question about the situation

Check your understanding

If you describe a simple real-life situation to Using objects to model real problems — like "there are 3 birds on a fence and 2 more land" — can they write a number sentence like 3 + 2 = 5 to represent it?
