Teacher sequence

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

    • Ask the learner to identify known quantities, the question, and a reasonable operation. For this addition and subtraction word problems set, begin without a timer.
  2. Model

    Demonstrate the situation model

    • Underline what is known, state what is being asked, and write one equation for each required step.
  3. Practice

    Assign the focused set

    • Require an equation, labeled work, and a sentence that answers the question. Regenerate only when the learner is ready for another arrangement of the same objective.
  4. Inspect

    Use errors to choose the next move

    • Choosing an operation from a keyword without understanding the situation. Watch for this specifically during addition and subtraction word problems practice.
    • Giving an unlabeled number that does not answer the stated question. Use the worked correction as the next teaching example.
