Counting to 100 Checker
Do numbers increase by 1 each time?
Are skip counting patterns consistent?
Do multiples of 10 end in 0?
Does the sequence reach 100?
Visual memory: Use number lines to track counting progress.
Pattern recognition: Skip counting creates predictable patterns.
Practice Rules:

• Counting forward: Each number is 1 more than the previous

• Skip counting by 2s: 2, 4, 6, 8, 10...

• Skip counting by 5s: 5, 10, 15, 20...

• Skip counting by 10s: 10, 20, 30, 40...

Practice strategies:
  1. Start with smaller ranges (1-10, then 1-20)
  2. Practice skip counting patterns regularly
  3. Use visual aids like number lines
  4. Check your work by counting backwards
Memory trick: "Skip count by tens, end in zero every time!"
