Skip Counting by 9s Practice
Build fluency with counting by 9s and track your progress with accuracy and streaks.
Student Tips:
- Count by 9s: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90…
- Cool pattern: the digits always add up to 9! (1+8=9, 2+7=9, 3+6=9)
- First digit goes up, second digit goes down: 09, 18, 27, 36…
- Think “nine, eighteen, twenty-seven…”
Teaching Instruction: Highlight the amazing digit pattern (digits sum to 9). Use finger tricks for 9s. This pattern is very visual on a hundreds chart – show the diagonal pattern.
