What students practise
I can tell the value of each digit in a number.
Students represent numbers with tens and ones (and hundreds), read and write them in several forms, and compare them.
Key words
- digit
- one of the symbols zero through nine
- place value
- the value of a digit from where it is in the number
- expanded form
- a number written as the sum of its place values
Common mistakes
- Gives a digit its face value instead of its place value.
- Compares the ones digits first.
- Leaves out a zero in a place with no value.
