Multiply the standard way: 5th grade math

Standard multiplication algorithm. A free 5th grade lesson plan, a question set with answers and a printable sheet with its key. Copy it and make it yours.

Lesson plan

Goal

  • Students can do this: standard multiplication algorithm.

Teach (10 min)

  • Multiply by the ones, then by the tens.
  • Add the two rows. A zero holds the ones place in the second row.
  • Work one example on the board while students say each step aloud, then do one together.

Practise (15 min)

  • Students work the printable sheet in pairs, then alone.
  • Or practise it as a game with no sign-up: https://peabody.kids/math/numsense.g5_mul3x2?lesson=5-numsense-mul-1&at=5

Exit ticket (5 min)

  • Three questions on a slip:
  • 1. Use the standard algorithm: 284 × 11 = ?
  • 2. Use the standard algorithm: 169 × 12 = ?
  • 3. Use the standard algorithm: 166 × 15 = ?
