Start with teaching the students to 'round up' by using a common method used to teach rounding called 'over 5'. This method takes a double-digit number, and if the number in the ones place is over 5, you round up to the next number. For example: 87 can be rounded to 90. 84 can be rounded to 80 because the number in the ones place is below 5.
