As a pediatric occupational therapist, one concern I hear from parents and teachers is: “My child is still reversing letters and numbers — should I be worried?”

Let’s break down why reversals happen and what we can do to support children effectively.

What Are Letter and Number Reversals?

Reversals occur when a child writes letters or numbers backward or flipped. Common examples include:

• b / d
• p / q
• w / m
• 2 / 5
• Writing entire words backward
• Starting letters from the wrong side

When Are Reversals Developmentally Appropriate?

It is developmentally appropriate for children to reverse letters and numbers up until the end of the second grade. The brain is still developing left-right awareness, visual discrimination skills, and motor planning abilities.

Children need a cognitive age of 5.5 to 6.5 to overcome up-down/vertical reversals (e.g. n/u, m/w) and 7.5 for left-right/horizontal reversals (e.g. b/d, p/q) (Harman, 1982).

If reversals persist beyond age 8, or interfere significantly with academic performance, further assessment may be warranted.

Why Do Reversals Happen?

From an occupational therapy lens, reversals usually reflect one or more underlying skill areas that need support.

1. Incomplete Left–Right Awareness

Children must understand directionality in their own bodies before consistently applying it to paper. If a child struggles to identify left and right, they may struggle with letter orientation.

2. Visual Discrimination Difficulties

Letters like b and d are mirror images. If a child has difficulty noticing small visual differences, confusion is common.

3. Visual Memory Challenges

Some children cannot easily recall how a letter looks once they begin writing. They may reconstruct it incorrectly.

4. Weak Motor Planning (Praxis)

Forming letters requires a stored motor plan. If that motor pattern isn’t solid, children may “guess” at formation.

5. Poor Directionality Concepts

Reading and writing move left to right. If directionality is inconsistent, reversals increase.

6. Rote Memorization Without Motor Experience

Worksheets alone do not build strong neural patterns. The brain learns letter orientation best through movement and multisensory input.

How Occupational Therapy Addresses Reversals:

1. Build Body-Based Left–Right Awareness

Before fixing letters on paper, we strengthen directional awareness in the body:

• Simon Says with left/right commands
• Obstacle courses with directional cues
• Ribbon dancing emphasizing crossing midline
• Tactile cues (sticker on right hand)

When the body understands direction, the pencil follows.

2. Teach Letters Through Multisensory Learning

Children remember what they feel and do.

Try:

• Writing in shaving cream
• Tracing letters in sand
• Forming letters with playdough
• Air writing with big arm movements
• Chalk on vertical surfaces

Large motor + tactile input builds stronger neural encoding.

3. Use Verbal Motor Scripts

Pair letters with simple directional language:

• b = “Make the /b/ bat, then the /b/ ball”
• d = “Make the /d/ doorknob, then the /d/ door”

Consistent scripts reinforce motor sequencing. Use the scripts that work for you.

4. Strengthen Visual Discrimination

Games that improve visual skills:

• Spot the difference
• Hidden pictures
• Matching games
• Puzzles
• Memory card games

Improved visual processing reduces confusion between mirrored forms.

5. Practice at the Right Difficulty Level

If a child reverses 6 letters consistently, isolate those 6 instead of drilling the entire alphabet.

Repetition should be:

• Short
• Focused
• Frequent
• Success-oriented
