Securing understanding of place value in integers
I can state the value of any digit in a given integer.
Lesson details
Key learning points
- It is difficult to know what a digit represents if you do not know its place value.
- An integer can be written as the sum of the place value of its digits.
- Rearranging the digits in an integer can alter its overall value.
Common misconception
Pupils may think the digit card 0 has to have significant place value.
If the question doesn't specify the number of digits, leading zeros can be used (and not written) to create integers with fewer digits.
