Complete a Sequence - Up to 20

Learn to recognize number patterns and fill in the missing numbers!

What is a Number Sequence?

Number sequences are like number trains!
A sequence is a special order of numbers that follows a pattern. Sometimes we have to figure out what comes next or what's missing in the pattern. Let's learn how to complete number sequences up to 20!

How to Complete a Sequence

1️⃣ Look at the numbers you can see

2️⃣ Find the pattern - are the numbers going up or down? By how much?

3️⃣ Fill in the missing number that fits the pattern

Parent Tips 🌟

  • Make it a game: Create number sequence hopscotch or use toys to make patterns more engaging.
  • Start simple: Begin with sequences that increase by 1 before trying larger jumps.
  • Use real objects: Line up blocks or toys to help visualize the sequence before writing numbers.
