Introduce, model, practice, inspect

Move through the sequence vertically. Each step has a distinct classroom decision rather than a hidden swipe panel.

  1. Introduce

    Set one visible purpose

    • Read each number aloud and identify the value, not only the name, of a digit. For this teen numbers: tens and ones set, begin without a timer.
  2. Model

    Demonstrate the model-to-symbol connection

    • Name the target place, use the digit to its right when rounding, and preserve every other place correctly.
  3. Practice

    Assign the focused set

    • Use expanded form to make regrouping and rounding decisions visible. Regenerate only when the learner is ready for another arrangement of the same objective.
  4. Inspect

    Use errors to choose the next move

    • Naming a digit's position but not its value. Watch for this specifically during teen numbers: tens and ones practice.
    • Rounding from the wrong neighboring digit. Use the worked correction as the next teaching example.
