Counting by 2s to 20

Learn to count by 2s up to 20! This interactive activity helps first graders master skip counting, which builds number sense and prepares kids for multiplication. Counting by 2s is a fun pattern that makes counting faster and easier.

Practice these skills:

• Count by 2s in sequence: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
• Recognize the pattern of even numbers
• Fill in missing numbers in skip counting sequences
• Start counting by 2s from any even number (not just 2)
• Build foundation for multiplication and division

How it works: Look at the skip counting sequence, find the missing numbers, and drag them into the correct spots. You’ll get instant feedback on every answer!

Tips for success: When counting by 2s, each number is 2 more than the one before it. You can also think of it as “counting only the even numbers” or “adding 2 each time”!
