Representation routine

Read the model before the symbols.

Treat the denominator as the number of equal parts and the numerator as the number of those parts being used.

Model focusAdd and subtract fractions and mixed numbers that share a denominator.
  1. 01

    Identify what each mark, part, or interval represents.

  2. 02

    Connect the representation to an equation or number statement.

  3. 03

    Use both forms to explain why the answer is reasonable.

01Problem

2 2/3 + 1 1/3 = ___

02 · Answer4
03 · Check

Treat the denominator as the number of equal parts and the numerator as the number of those parts being used. This example supports the page objective: Add and subtract fractions and mixed numbers that share a denominator.

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

    • Use fraction strips or number lines to connect symbols with quantities. For this add and subtract fractions with like denominators set, begin without a timer.
  2. Model

    Demonstrate the model-to-symbol connection

    • Treat the denominator as the number of equal parts and the numerator as the number of those parts being used.
  3. Practice

    Assign the focused set

    • Have the learner state what the numerator and denominator mean in each problem. Regenerate only when the learner is ready for another arrangement of the same objective.
  4. Inspect

    Use errors to choose the next move

    • Comparing denominators as if a larger denominator always means a larger fraction. Watch for this specifically during add and subtract fractions with like denominators practice.
    • Adding or multiplying numerators and denominators with the wrong operation rule. Use the worked correction as the next teaching example.
