Percentage - A percentage is a proportion of a whole.
Pupils may struggle when finding 10% or 1% of numbers that include zero.
Draw attention to zero being a placeholder within specific numbers. Some pupils may still need to use resources such as number cards and place value charts to physically move the digits to develop their confidence in dividing by 10 and 100
