How to teach this
Have your child say the hidden fact first: for 60 × 7, that's 6 × 7 = 42. Then ask "forty-two whats?" Tens. So the zero comes from meaning, not a trick. Most misses here are missing or extra zeros, so have them check whether each answer looks about ten times the basic fact.
Watch for: Kids forget the zero and write 4 × 30 = 12. The answer is 12 tens, so 120. Kids add a zero to everything and turn 60 × 7 into 4,200. One factor has one zero, so the answer gets one: 420.
Common questions about multiplying by multiples of 10
- Does my child need to know times tables first?
- It helps a lot. Each problem is a basic fact wearing a zero, so shaky facts make this page frustrating. Warm up with fact practice if needed.
- Should I teach 'just add a zero'?
- Teach the why alongside the shortcut: 4 × 30 means 4 groups of 3 tens, which is 12 tens. Children who only know the trick misplace zeros later in multi-digit work.
