Lesson details
Key learning points
- Dividing by ten moves all the digits one column to the right making them one tenth times the size.
- If you divide a multiple of 10 by ten, the numbers move one place to the right and the zero in the ones disappears.
- The zero only disappears if you are dividing a multiple of 10 by ten.
Keywords
Placeholder - A placeholder is where we use the digit zero to hold a place in a number and maintain place value.
Magnitude - The magnitude of a number is its distance from zero.
Common misconception
Many pupils believe that 'subtracting zero' is dividing by 10 which can lead to difficulties later on when they are introduced to decimal numbers.
Don't dismiss it. It's a pattern that has been spotted and generalised. Do encourage the children to work with physical resources that don't involve the numbers themselves so they can see that it's not subtracting zero but changing place value.
