Lessons

Study first

  • First Multiplication Patterns

    Start multiplication through repeatable groups, clear roles, and bead movement you can actually follow.

    Open lesson →
  • First Division Patterns

    Begin division through equal groups and missing-factor thinking before more formal quotient building.

    Open lesson →
  • Place Shifts in Multiplication

    Learn how multiplication changes place, so problems like 12 × 3 feel structured instead of chaotic.

    Open lesson →
  • Building Quotients in Division

    Extend exact division into stronger quotient-finding habits so the operation feels deliberate instead of lucky.

Exercises

Practice next

  • Multiply 3 by 4

    Repeated addition is a gentle way to enter multiplication structure.

    Open exercise →
  • Multiply 4 by 3

    Seeing the same total through another grouping helps flexibility.

    Open exercise →
  • Divide 12 by 3

    Exact division becomes easier when you check it with repeated addition.

    Open exercise →
  • Divide 12 by 4

    Try checking the result with 3 + 3 + 3 + 3.

    Open exercise →
  • Multiply 12 by 3

    Place-aware multiplication becomes easier when tens and ones are treated as separate partial products.

    Open exercise →
  • Multiply 14 by 4

    This drill reinforces that the tens product and ones product must stay aligned before they are combined.

    Open exercise →
  • Divide 24 by 6

    Exact division stays stable when you search for the missing factor and check it immediately with multiplication.

    Open exercise →
  • Divide 36 by 9

    This drill strengthens exact quotient recognition and checks whether you can trust multiplication facts during division.

    Open exercise →
  • Six-times table ladder

    This exercise reinforces one multiplication family so repeated structure starts to feel familiar instead of random.

    Open exercise →
  • Multiply 23 by 4

    This is a stronger place-shift drill because the tens product and ones product both matter and must stay aligned.

    Open exercise →
  • Divide 48 by 6

    This is a clean division-facts exercise that keeps the factor family visible and exact.

    Open exercise →
  • Divide 63 by 7

    This quotient-building exercise is useful because it stretches the exact fact family a little further without introducing remainders.
