# Counting by 10s

This packet helps students practice a core number sense skill: counting by 10s. This packet focuses on the more difficult type of counting by 10s: starting with any number. Each set asks students to count the by 10, for the next ten numbers. This packet helps students understand how to count by 10s, how to add 10s, and how to figure out "ten more than." So, the packet is good for first grade students learning to count by 10s, learning to add 10s, and learning the patterns involved in numbers (that when you add 10, you just change the tens place), and learning to find "ten more than" and "ten less than."
