Skip counting by 5, 10, and 100

Skip count fluently by 5s, 10s, and 100s starting from any number.

Skip counting means jumping by the same amount each time instead of counting by ones. Counting by 10s from 40 goes 40, 50, 60, 70 -- much faster than counting one at a time.

You can skip count starting from ANY number, not just from zero. Skip counting by 100 from 235 goes 235, 335, 435 -- only the hundreds digit changes.

📋 For the teacher
Teach it (10–15 min):
  • Practice starting from odd, non-round numbers (like 47 or 264), not just from 0 or 10 -- that is the real second-grade skill.
  • Use a hundreds chart for 5s and 10s so they can see the pattern of columns.
  • For skip counting by 100, point out that only one digit is changing -- that is a great shortcut to notice.
  • Mix the three skip counts in one sitting so they learn to switch between them.
Talk about it:
  • What is the difference between skip counting by 10 and by 100?
  • When you skip count by 100, which digit changes and which digits stay the same?
  • Can you skip count by 5 starting from a number that is not a multiple of 5, like 22?

Mastery looks like: They skip count by 5s, 10s, and 100s starting from any given number, without counting by ones.

Common stumbles: Reverting to counting by ones when the start number is not round; changing the wrong digit when skip counting by 100.
