Key idea

Digits move; the point stays. One place left is ten times as much, one place right is one tenth. The exponent of 10 says how many places.

Sample problems

  1. Work out 3.4 × 10
  2. Work out 3.4 × 100
  3. Work out 3.4 × 1000
  4. Work out 62 ÷ 10

Common mistakes to watch for

  • Answered 0.60 — the same amount as 0.6, so nothing was multiplied.
  • Answered 2.700 — zeros added rather than digits moved; or 27, reading the exponent as one place.
  • Answered 450 unchanged, or 0.450. Every wrong answer here is the same amount as the number started with, which is the give-away.

The answer key explains each one, so you can tell what a wrong answer means.

How to use this set

  1. Teach with the slides (about 15 minutes), or watch the video together.
  2. Practice with the worksheet. Questions climb from fluency to application to reasoning.
  3. Check understanding with the exit ticket.
  4. Mark with the answer key — each answer shows the steps and the most likely mistake.
