B and d letter reversal

When b and d letter reversal becomes an issue …

Writing by hand requires a child to correctly identify the sticks, curves and/or circles that make up a letter, then reproduce those shapes in a particular orientation, using a set sequence of pen strokes. Before the skill is automatized, the handwriting process can be quite mentally taxing. New writers are also struggling to develop the fine motor skills needed to grip a pen or pencil and the language encoding skills required for reading and spelling.

Add to this the challenge of writing in a straight line and creating letters of the same height and width and you’ll find that reversing letters is a common mistake for beginners to make. This is particularly the case for symbols built from the same set of shapes, including b/d, p/q, f/t, i/j, m/w and n/u. Nonetheless, most children grow out of letter reversal by age 7 and it only becomes a cause for concern when errors occur beyond first and second grade.

That’s because an older child who reverses letters despite having been taught proper letter formation may be struggling with a specific learning difficulty or a physical impairment that can also impact on reading skills. It’s important for any issues to be identified early on so the right accommodations and strategy instruction can be put in place.

Causes of letter reversals in older children

Dyslexia

Dyslexia is a language-based learning difference that primarily affects reading and spelling skills and is commonly associated with letter reversals. Not all children with dyslexia will exhibit reversals, particularly in cases where the dyslexia is mild.

However, 8 out of 10 dyslexics have trouble with directional knowledge, which can make the kind of left-right and up-down flipping seen in b/d, p/q and 6/9 reversals more likely to occur. If dyslexia is the reason for the letter reversals, teachers may also note that students struggle with letter and number sequencing – which can lead to poor and inconsistent spelling, and difficulty doing simple maths.

A word of caution: Because letter reversals are an easy way to visually represent a language difficulty, they are often used to accompany articles and blogs about dyslexia. Nonetheless, there is no evidence to suggest letter reversals are more common amongst dyslexic children, compared to same-aged peers learning how to read and write. It is more so that most children grow out of letter reversals, but dyslexic kids who are cognitively overloaded from other elements of reading and writing, including sound-letter mapping, may be slower to.

Did you know that phonological processing, the ability to split a word into its component sounds and then accurately map those sounds to letters, is the most common cause of the literacy skills difficulties experienced by people with dyslexia?

Visual processing disorders and/or visual impairments

These can also cause letter reversals. In fact, people with visual processing disorders commonly confuse letters and numbers that are of similar shapes. This is because while there is no disruption to sight, the brain struggles to interpret the information it receives during reading. A child who has a whole/part visual disorder may not recognize all of the shapes that form a letter as one unit. A child who has visual impairment, can struggle with letter formation as a result of decreased exposure to letters during reading.

In certain cases of ADHD, impulsivity can lead to letter reversals, particularly when a child rushes the pen strokes of a letter and does not proofread his or her own work. Some children with dyspraxia, a motor skills difficulty that impacts fine and gross motor skills, find handwriting so physically challenging that flipped and reversed letters occur due to exhaustion of cognitive resources. Dysgraphia is another writing specific condition that can result in incoherent text and illegible handwriting, including letter reversals.

Confidence and self-esteem

As is the case for many reading and writing based learning difficulties, a child who falls behind his or her peers is at risk for experiencing low self-esteem, embarrassment and a lack of confidence in the classroom. Letter reversals are particularly noticeable errors and fear of making them may disrupt fluency in writing and interfere with a child’s ability to express him or herself.

This can make a child more reluctant to participate in group activities, especially when writing on the board is involved, and create a negative attitude toward school and learning. In the case of reversals because of a specific learning difficulty, there can be more far-reaching consequences if reading is also disrupted and the problem goes undiagnosed.

Teaching letters, reading, and handwriting

Learning to write by hand

When children start learning how to read and write at school they usually have a pretty good idea of what letters look like. This is thanks to pre-literacy skills development from children’s songs, having been read to by parents and teachers, and playing with letter blocks and other educational toys. Some children can even write the letters in their name. Learn more about the 6 pre-literacy skills.

The goal in teaching writing is to call attention to all of the letters of the alphabet, introducing them one at a time. You can start with capital letters, lowercase, or present them both together. However you go about it, it’s important to have students practice making the lines and curves needed to create a shape. This means going over each pen stroke in a sequence.

It’s recommended to model a letter and then take a multi-sensory approach that helps reinforce the shape in memory - in addition to pen and paper workbook activities. Keep in mind that while many children have experience holding a writing instrument for drawing, figuring out how to grip a pen or pencil and apply the right amount of pressure can take some getting used to. This is especially true of kids who struggle with dysgraphia and dyspraxia.
 
TOP TIP: Ever noticed how some children prefer to write in all caps? Capital letters are less complex than lowercase letters and are consequently easier for a child to write and process. Learn more about the difference between capital letters and lowercase.

Writing instruction is accompanied by phonics lessons to teach reading skills including sound-letter correspondence and common letter combinations. Children are thus simultaneously learning to read, write and spell, which is a cognitively demanding task.

As fine motor skills develop, forming same-size and proportionate letters that are neat and evenly spaced becomes easier and eventually§  the writing skill is automatized. This typically occurs by the end of the second grade. Students will then go on to learn the cursive script and sometimes even touch-typing in later grades.

Top tips for keeping commonly confused pairs straight 

  1. Put up posters. Before a child can correctly write a letter, he or she needs to quickly recognize it. The more you reinforce the letters of the alphabet through repeat exposure in reading, the easier this will be. If a student is struggling with particular pairs such as b and d, try creating two big posters and putting them near a classroom cue (d near the door and b by the blackboard).

  2. Make collages for problematic letters. Writing workbooks will usually include words that start with a particular letter. Go one step further and bring in family photos of relatives whose names begin with that letter. Next, cut out pictures from magazines of words that are meaningful to the child. Just the activity of looking for images that begin with a particular letter can help! On a separate piece of paper write down the name of every image in the collage and attach it to the bottom of the poster, then put it up on the wall. You may find students work on different letters depending on their individual needs.

  3. Play sorting and memory games. Get some letter cards and play sorting games where students have to make pairs of capital and lowercase or flip them over and have children remember which is where, such as in go fish.

  4. Teach letters formed with similar strokes. A lowercase c and d have the same pen stroke, which can also be found in o, q and g. Teach kids how to form this curve and then practice creating words out of these letters, while drawing images to reinforce the shape. For example, you could put the word cod on the board and have everyone draw a fish with scales made out of a c shape, or write dog with tail wags or long hairs that look like a c.

  5. Pair letters with concrete objects to create visual aids. Some people draw a baseball or cricket bat over the lowercase b. Others will turn the d into a drum with a drumstick or have back-to-back chairs that represent the d and b. The d can be a doorknob or a dinosaur – some people even use them to create a bed drawn over the word. Get creative and brainstorm a list of shapes that can help your students remember the differences between commonly reversed letters. 

  6. Develop some audio cues for writing. Putting together a script that students can say aloud to themselves before they write a letter is sometimes useful. For example, over and around the bend then up and back down for d. For b, first comes the down-stroke for the bat and then the ball.

  7. Practice visualising letters with eyes closed. Have students look at a letter then close their eyes and draw the shape in the air with their finger. You can also provide sensory materials such as sand, dirt, even shaving cream, where the shape can be traced with eyes both open and closed. This multi-sensory activity adds a kinaesthetic element to the learning. Learn more about taking a multi-sensory approach.

  8. Get out the play-doh or clay. Building letters is another dynamic activity that can help reinforce a shape in memory. Students can pack the dough down flat and cut shapes out with a plastic knife or build a 3D model of the letter. For kids who are keen, suggest they also create an animal or object whose name begins with that letter. Take pictures of these creations and put them up around the room if the dough needs to be recycled.

  9. Go for the glitter. Decorating letters with glitter or strands of yarn is another fun activity, along with coloring them in with different types of markers, pens, pencils and crayons.

  10. Use color to distinguish letter pairs. Circle the letters d and b in word searches, color them in charts and underline them on worksheets using a different color for each. Next have students switch sheets and see if they can find any their partner missed. Do one letter at a time.

In general, it helps to spend more time on one letter in a commonly reversed pair, before introducing the other. That’s because presenting them simultaneously can lead to greater confusion. Studies in applied linguistics have shown that when we have to master a group of words, it is more difficult to achieve high accuracy if they look and sound similar, or have a related meaning. There are also apps available for tablets and iPhones that turn letter reversal drills into games.

Mind your P’s and Q’s: Helping students who don’t want help

For students who are resistant to targeted reading and writing activities, sometimes it’s useful to introduce an accommodation that isn’t perceived as directly addressing the problem. One useful approach for students who are 7 and older is to offer touch-typing lessons. A multi-sensory program like Touch-type Read and Spell presents a letter, letter combinations and words on the screen, plays an audio and then directs the child as to where to type the letter.

Keyboarding uses muscle memory in the fingers to override handwriting issues and repeat drills to reinforce correct letter orientation. Learning to type is also a handy accommodation for students who struggle with dyspraxia, dysgraphia, visual processing disorders and ADHD for everything from note-taking in class to doing homework and taking exams. Learn more about the benefits of touch-typing.
