Eight numeric sequences — counting by tens, fives, and twos, both ascending and descending, such as 10, 20, 30, __, __, 60, __, __ and 45, 40, __, 30, 25, 20, 15 — ask students to fill in the missing numbers in each pattern. The worksheet presents the sequences in a simple fill-in-the-blank layout with space to write in the missing values. A lettered answer list from A through H appears on a separate second page, giving the complete run of numbers for each row so students or teachers can self-check. The mix of step sizes and directions gives practice with skip counting in both directions in a single sitting, making it suitable as morning work, homework, or a quick formative check.
