Computation routine

Calculate, check, explain.

Read the value and relationship of each number before choosing a symbol or missing value.

  1. 01

    Name the operation and useful number relationships.

  2. 02

    Solve with an efficient written or mental strategy.

  3. 03

    Check the result with the inverse operation or an estimate.

01Problem

Complete the factor pair for 90: 10 × ___ = 90

02 · Answer9
03 · Check

Read the value and relationship of each number before choosing a symbol or missing value. This example supports the page objective: Find factor pairs, identify multiples, and classify whole numbers as prime or composite.

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 counters or a number line before moving to symbols alone. For this factors, multiples, prime, and composite numbers set, begin without a timer.
  2. Model

    Demonstrate the calculation strategy

    • Read the value and relationship of each number before choosing a symbol or missing value.
  3. Practice

    Assign the focused set

    • Ask for a short explanation of how the learner knows which number is greater. Regenerate only when the learner is ready for another arrangement of the same objective.
  4. Inspect

    Use errors to choose the next move

    • Comparing the shape of digits instead of their numerical value. Watch for this specifically during factors, multiples, prime, and composite numbers practice.
    • Treating a number sequence as memorized words without noticing its structure. Use the worked correction as the next teaching example.
