How to Use Visual Task Analyses for Teaching Tooth Brushing
A task analysis breaks a complex skill into discrete, teachable steps. When you add pictures to each step, you give the learner a visual reference they can check against independently. For something like tooth brushing, that typically means 8 to 12 steps depending on how detailed you want to get. I use this with kids who are nonverbal or have significant apraxia, and it works because the visual removes the need for me to stand there and prompt every single movement. Here is what a standard sequence looks like before you print anything: Step 1: Pick up the toothbrush
Step 2: Wet the brush with water
Step 3: Apply pea-sized amount of toothpaste
Step 4: Brush the outside of the upper teeth
Step 5: Brush the inside of the upper teeth
Step 6: Brush the outside of the lower teeth
Step 7: Brush the inside of the lower teeth
Step 8: Brush the chewing surfaces
Step 9: Spit out toothpaste
Step 10: Rinse mouth with water
Step 11: Rinse the toothbrush
Step 12: Put the toothbrush away
Where to Find a Printable Brushing Teeth Task Analysis With Pictures
The simplest route is Boardmaker or SymbolStix if your organization already has a license. They have pre-made dental care symbols you can string together in minutes. If you are working without a subscription, MyShapedDocs offers free downloadable task analysis templates with built-in clipart, and you can export as PDF. For a truly no-cost option, the Autism Speaks tool kit has printable visual schedules with icons you can rearrange. Any of those will give you a clean, laminatable strip you can hang on the bathroom wall. What matters more than the source is the layout. Put the pictures in a left-to-right sequence. Number them. Make sure each image shows the specific action, not just a generic toothbrush icon. A picture of a toothbrush next to a sink doesn't tell the child whether to wet the brush first or apply paste first. You have to be explicit. I ran into a specific problem last year with a seven-year-old who could complete every step independently except step three. He would put toothpaste on the brush, then immediately dip it in water, which turned the paste into a slimy mess and made him reject the whole routine. The issue wasn't sequencing. It was that he didn't understand the difference between wetting the brush before paste versus after. I took a photo of his actual toothbrush loaded with paste, and another of his actual brush sitting next to the paste tube. I swapped the generic clipart for his real photos and that resolved it. Generic symbols work for most kids. Some kids need their actual environment represented to make the connection.
What People Get Wrong About Picture-Based Task Analyses
The biggest mistake I see is assuming the visual itself teaches the skill. It does not. The pictures are a prompt, not the instruction. The child still needs to be taught each step through modeling, physical guidance, or chaining. The visual just reduces the number of verbal prompts you have to give over time. Without the teaching component, the child learns to look at the picture and then look at you waiting for more direction. That is a prompt dependency, and it defeats the whole purpose. Another common error is making the sequence too long. If you have more than twelve steps, working memory starts to break down, especially for kids with auditory processing delays. Combine steps when you can. "Apply toothpaste and put the cap back on" can be one picture if the learner is ready for that level of chunking. Fewer steps with higher accuracy beats more steps with constant errors every time.

Setting It Up So It Actually Works
Print the task analysis on cardstock and laminate it. Tape it to the wall at the learner's eye level, right next to the sink where the brushing happens. Proximity matters. If the visual is on a shelf across the room, the child will not reference it consistently. You want it in the same visual field as the materials needed for each step. Start with backward chaining. Let the child complete the last step independently while you handle everything leading up to it. They get the natural reinforcement of finishing the routine. Then gradually add the previous step, then the one before that. This is faster than forward chaining for most learners because the reward is immediate from day one. Fade your prompts systematically. If you are standing beside the child and pointing at each picture as they go, that is a physical and gestural prompt. Move to just pointing. Then move to the child checking the strip independently. Then remove the strip entirely once the skill is solid. The goal is independence from the visual, not permanent dependence on it.
When This Approach Fails
Picture-based task analyses do not work for every learner. If a child has object permanence issues or visual processing disorders that make two-dimensional images difficult to interpret, printed clipart will not help. In those cases, video modeling or live person modeling is more effective. There is also a ceiling effect. Once a child masters tooth brushing at around eight to ten steps, adding more detailed sub-steps for precision cleaning is better taught through direct instruction rather than expanding the visual strip further. The method also breaks down if the environment is inconsistent. A child who brushes teeth at home using one sequence and then goes to a group home or school where the sink layout, brush type, and routine are completely different will struggle to transfer the skill. Keep the visual consistent across settings or create separate strips for each environment and teach generalization explicitly. It takes more time upfront but prevents the regression I see constantly when kids move between environments without a planned transfer.
Building Your Own Strip Quick
If you need something custom and cannot find a ready-made set, here is a practical workflow. Take clear photos of your own materials. Same toothpaste tube. Same brush. Same sink. That consistency between the photo and the real object reduces cognitive load. Arrange them in a grid using any basic document editor. Add a number or small arrow between each one so the sequence direction is obvious. Print at actual size. Laminate. Stick it on the wall. That entire process takes about twenty minutes from start to finished product. The Printable Brushing Teeth Task Analysis With Pictures you end up using does not need to be professional grade. It needs to be clear, consistent, and positioned where the child can actually see it while they are doing the task. Anything extra is decoration, and decoration does not teach.
