Students who struggle with rounding often have trouble with the abstract nature of using place value to determine rounding solutions. Number lines offer a more concrete approach that makes more sense to some students.
Being able to fluently round to tens and hundreds is a basic skill.
Students should plot where each number is located and then circle the ten or hundred to which it is closest. On the first page, 2 examples are given for rounding to tens and hundreds, 10 problems are provided with numbers given, other pages with 12 problems are given, and then a separate page which can be filled with numbers of teacher’s choice are given.
