Why do some kids write numbers backwards?

Español

  • Quick tip 1

    Gently point out mistakes.

    If you sense confusion, show how to write the number the correct way. If you need a hand, consider asking another trusted adult or an older sibling to do this instead.

  • Quick tip 2

    Make it tactile.

    Have kids trace numbers on sandpaper or write numbers with their fingers in shaving cream or pudding. 

  • Quick tip 3

    Do it over and over again.

    Repetition builds muscle memory. Some kids need to practice many times before they can consistently form numbers the right way.

  • Quick tip 4

    Praise the effort.

    When you see hard work or progress, acknowledge it. The end result doesn’t have to be perfect — it’s the work that matters. Be specific. For example, “Your 3’s are all correct today! You must be so proud. Your hard work is paying off.”

Lots of young kids write numbers backwards. (Teachers may call it reversal.) In fact, it’s developmentally appropriate for kids under 7. But when kids are still reversing numbers after age 7, they may need extra help learning to write them correctly. 

When kids have trouble writing numbers the right way, it’s not a problem with understanding math. The numbers they’re using are correct — they’re just written incorrectly. Instead, it’s an issue of how their brain processes what they see.

Writing numbers backwards can cause challenges in math class or with homework, but it doesn’t mean kids are “bad at math.” 

Keep in mind, too, that some kids have a related difficulty that can impact math. They transpose numbers. Instead of writing 32, they’ll write 23. That throws off their computation and leads to wrong answers.
