How to implement Commenting with PECS

Phase 6 of the Picture Exchange Communication System® – Commenting with PECS ® is my favourite phase. In this post I will look at how to implement phase 6 and some commenting activity ideas.

If you are new to the Picture Exchange Communication System (PECS) then start at my post on phase one. For the rest of this post I will assume readers are familiar with PECS and have mastered up to phase 5.

What is Phase 6 of PECS?

Phase six of the Picture Exchange Communication System (PECS) is commenting.  It is about identifying items and commenting on them.

Up until phase 6 the focus has been on asking for something and getting it in return.  Phase 6 is about using language to label or name things.  This is such an important skill and the intention is to end up with spontaneous (un-prompted) commenting.

How to implement PECS phase 6

To start with use words they already know and understand, the initial focus is to introduce new sentence starters such as ‘I See’, ‘It’s’ and ‘I Hear’.

PECS Sentence Starters

Avoid using favourite items (reinforcers) they have been asking for with ‘I Want’ when introducing new sentence starters.  If you hold up a biscuit and ask a child to name it they will expect to get the biscuit not to comment on it! It is important to ensure the difference between ‘I See’ and ‘I Want’ is clear, you could simply use a photo or flashcard.

Put the new sentence starter such as ‘I See’ on the front of the communication book, hold up the item and ask’ ‘What do you see?’  If the learner doesn’t go to pick up the new sentence starter then use silent physical prompting to guide them.  The learner should be able to complete the sentence strip but instead of getting the item they get social reinforcement – ‘yes a dog’.

Each time you do an exchange use delayed prompting to give them a chance.  Then as appropriate for the learner, fade out the prompts until the only prompt is the verbal question.

Use the 4-step error correction method as with the previous phases – Model, Prompt, Switch and Repeat.

We started off doing our commenting with PECS as lessons at the kitchen table.  This meant we could concentrate and there were no distractions.  To get the most out of your time try and have a couple of different commenting activities prepared that you can grab at an convenient time. 

Your child may be better at certain times of day, it’s much better to introduce something new when they are in a more receptive mood.  If they are overexcited or tired it will be a battle and not a good start so pick your moment (by the time you have got to phase six you should be pretty good at doing this).

When the learner is confident with the first sentence starter do some discrimination. Do this in the same way you did for phase three but with the sentence starters.  Use the 4-step error correction method until they are confidently using the sentence starter correctly.  Then you can introduce new sentence starters – ‘I hear’, ‘I feel’ etc.

Phase 6 tips

  • Use words they already know
  • Don’t use reinforcers when introducing new sentence starters
  • Use the front of the communication book
  • Ask the question
  • Prompt when necessary and fade out prompts as appropriate
  • Use social reinforcement
  • Use 4-step error correction method
  • Start in a sensible / quiet teaching environment – such as at the table.
  • Be Prepared

Rewards and encouragement

Let’s face it not all kids are going to come and play ball when we want! We used the PECS UK Lets’s Make A Deal token system (see picture below). You can use any reward system such as stickers on a chart.  This has really helped us when my son doesn’t want to do an activity.  Even helped him learn to put up with getting his nails cut!!

Commenting with PECS Activities

It’s & I see – Labelling with books and toys

One of my favourite commenting with PECS activities is using lift the flap books.  The best thing about lifting the flap is it is easy to understand what the learner needs to identify.  This is the same concept as having toys in a bag that you pull out. If there is only one object it is clear what needs identifying.  Starting off with lift the flap books is a great way to introduce commenting on books.

Dear Zoo

We have probably used Dear Zoo for commenting hundreds of times, my son loves it.  It is a really good one to start commenting with, particularly if they are already familiar with the book.

Dear Zoo Commenting – I see giraffe

We also use toy animals in a bag and pull them out asking What is it?

Postman Bear

Postman Bear is a lovely book from the Tales from Acorn Wood series by Julia Donaldson and Axel Scheffler.  They are lovely lift the flap books and fantastic for commenting lessons.

It’s Mole

Books give you the freedom to comment based on the learners level.  Above is a simple exchange looking at just the animal behind the flap. Whilst the sentence below is much longer and more complex.

Use the Learner’s Favourite books

My son is a big fan of Spot the Dog and these simple books are fantastic for commenting.  We really enjoyed using Spots Toys.

I see Spot and boat

Again you can mix it up by using the objects from the book. However do be careful only to do this when the learner has mastered the difference between requesting and commenting.

Ten Little Pirates is another favourite book in our house. And great for commenting using numbers. I credit this book (and Numberblocks) with teaching both my boys to count.

Commenting with PECS & Attributes

As you start to master commenting you can add in attributes. Make sure the activity is appropriate for the learner’s level.  Good ones to start with are size, numbers, colours and shape. As the learner gets more confident or able you can increase the sentence length and complexity.

Here we use a Peppa Pig Shapes book and just identify the shape.

Next we can introduce the colour:

Then we add in Peppa Pig too:

Hide and Seek

Hide and seek is a great way to encourage spontaneous commenting while having fun.  You probably need two adults to introduce this one or a child that can do the hiding.  I might hide behind the sofa and jump out and my husband will ask Who do you See? And hopefully you get I see Mummy. 

I See Mummy
It’s Mummy

It is great to encourage commenting throughout the day.  I might prompt for my son to comment ‘I see Daddy’ with his PECS when he comes home from work.  We have cats so when they come in the room we can comment that we see them. Although I think my son thinks the cat’s name is cat now!

I see cat

Use the TV or iPad

Let’s face it most kids love technology, so use that to your advantage.  My son loves the film SING which is full of different animal characters.  I made up some PECS cards for the characters and we then did an activity where my son would identify what animal each character is.  He loved this activity and enjoyed showing off that he knew what they all were.

SING commenting

We have big Gruffalo fans in our house so we needed to make up PECS cards with all the characters. When watching the film or reading the book we can comment on who we see.

Gruffalo PECS

Another favourite is Thomas the Tank Engine and we can comment when he comes on the TV. You can even try and pause the TV to comment on what the character is doing.  Do this with caution it may not be appreciated if you pause at a vital moment in the programme.

Get Out and About

We actually have two communication books, one for the house and the other lives by the door so goes with him whenever he leaves the house.

A really successful outing was Longleat Safari. I sat in the back of the car with my son whilst our youngest was up front with his Dad.  This meant as we went round the safari my son was able to comment on what he could see.  He was so happy and engaged it was great. Since the Covid lockdown we have been able to do this with the virtual safari’s on Youtube.

PECS at the zoo

Often the PECS you need for a certain outing are not in your communication book.  I have found taking a pencil case in my handbag with the cards we may need useful.  If we go to the farm I can pull them out stick them on the front of his book and he can start naming the animals as we see them.

Going on a nature walk

You can do this one in the park or garden to start off, there are so many things to see and get commenting on with PECS.

If you are out with other people it is a great time to use PECS.  The more people in your circle you expose to PECS the more likely they are to get it.  Some of our friends are now confident doing PECS exchanges and encouraging my son to do so.  Kids love PECS and really like being able to engage with my son, my nieces and friends kids are very happy when they get to do a commenting activities with my son – it’s a good turn-taking lesson and helps them understand PECS / different ways to communicate.

Other activities

Using a viewfinder was good fun, it took my son a while to grasp how to do it but he really enjoyed it when we got there.  I found this a nice way to introduce some different vocabulary such as sea creatures.


We are still struggling with some concepts such as next to, between and behind.  To start with we used objects such as Postman Pat and his van to grasp in and on.  You can also do this with dolls in a toy bed or a toy cat / dog in a basket.

I Hear

One of the best activities to comment on what you hear is the PECS I Hear Animals app.  My son really likes using the iPad so this was a good fit for us.  Another option is to record sounds on your phone such as people’s voices or vehicles.

You can also use the I Hear sentence starter more spontaneously, such as I hear bird when you are in the garden.

I hear bird

Help & PECS Resources

It is really easy to make up PECS cards yourself and I talk about this in my post on making and storing PECS cards.

I really recommend doing the official PECS training course if you haven’t already.

I love this really helpful PDF from PECS on Materials for Attributes and Commenting Lessons.

It may also be worth looking at the PECS YouTube Channel.

Personally I have found PECS a huge help for my son, his understanding and ability to engage with others has come on enormously.  I am so thankful that he has the skills to communicate when he wants to.  PECS has helped stop so much frustration when he couldn’t say what he wanted verbally.

    Wow – I never thought of doing this with PECS. We are trying to encourage commenting at the moment but the school haven’t suggested using PECS for it and we used to do PECS (stage 4) a few years ago. Thanks for sharing with #spectrumsunday

      I think my son has learnt so many words just from doing commenting with PECS. It’s well worth it. Happy to share with #spectrumsunday
