About missing number worksheets

A number train is missing a car. Kids look at the numbers, work out the counting rule, and circle the number that fills the gap. It's great practice for number order and skip counting. Choosing from a few answers lets kids check their own thinking as they go.

Kindergarteners count by ones. First and second graders skip count by twos, fives and tens. Older kids tackle threes, fours, 25s, 50s and 100s, and sometimes count backward, so they have to find the rule before answering. New number trains appear with every print.
