NC.2.NBT.2

Students count within 1,000, including counting on from a given number without having to go back and start at one. 

In Kindergarten, students skip counted by 10 up to 100. Students in second-grade build on this work as they skip count by 5s, 10s, and 100s. 

• Students are expected to skip count proficiently applying patterns within the counting sequence by 5s, 10s, and 100s. For example, when skip counting by 5s starting at 0 using a 100s board or number line, students learn that the ones digit alternates between 5 and 0. When students skip count by 100s, they discover that the hundreds digit is the only digit that changes and that it increases by one number each time.
