Grade 1 Counting: Counting to 100
Count all the way to 100
What You'll Learn
- Count from 1 to 100
- Recognize decade patterns (20, 30, 40...)
- Fill in missing numbers in longer sequences
📖Counting Higher
After 20, the pattern continues: 21, 22, 23... When you reach 29, the next number is 30!
💡
Each group of ten has the same pattern. 31-39 is like 21-29, just with a 3 in front!
