Big vs. Little and Features: Using Descriptive Words to Build Language in Children with Autism

Dr. Mary Barbera

  • Discover how teaching big vs. little with real objects—like stuffed animals—can build early language and thinking skills in kids with autism.

  • Learn simple ways to teach descriptive words like stripes, tails, and colors to help your child understand and communicate more effectively.

  • Use what you already have at home—books, toys, and stuffed animals—to turn everyday moments into powerful language-building opportunities.

When it comes to teaching children with autism or signs of autism, we often focus on language, daily routines, and reducing problem behaviors. But did you know that teaching features, sizes like “big” and “little,” and other descriptive language can dramatically expand a child’s understanding and ability to communicate?

I’m Dr. Mary Barbera, autism mom, Board Certified Behavior Analyst, and author of Turn Autism Around. In today’s blog, I want to show you how teaching descriptive language like “big” and “little”—and focusing on features—can help young children make major gains in their language and cognitive skill

Why Teach Big and Little?

Many children with autism or signs of autism struggle with understanding and using descriptors like “big” and “little.” These concepts seem simple, but they require a level of abstraction that can be challenging for early learners.

Teaching size differences helps with:

  • Vocabulary expansion

  • Generalization of concepts

  • Following instructions in real-life settings (e.g., “Get the big spoon”)

We don’t want children to just memorize labels. We want them to truly understand and use these concepts functionally across environments.

Prerequisites to Teaching Big vs. Little

Before diving into teaching size concepts like big vs. little, it’s important to make sure your child has a few foundational skills in place. Ideally, your child should already be able to match identical objects and attend to visual differences in size, shape, or color. They should also be working on or have some ability to follow simple directions and engage in short table-time or floor-based learning activities. If your child is not yet labeling basic nouns (like “ball” or “car”), focus on building that receptive and expressive vocabulary first. Once these early skills are emerging, teaching size comparisons becomes both more meaningful and more effective.

Starting Attributes with Matching and Sorting

Before diving into labeling or requesting “big” or “little,” we need to build a solid foundation. One of the best ways to start is with matching and sorting activities using real objects and photos.

  • Start with identical objects in different sizes (e.g., two balls or two animals).
  • Have your child match “big ball to big ball” and “little ball to little ball.”
  • Use the same type of object to avoid confusion due to shape or color differences.

This reduces distractions and helps kids focus on size as the defining feature.

Labeling Big Vs. Little

Once your child can match objects by size, you can begin to teach the labels “big” and “little.”

Try holding up two items—say, a big cat and a little cat—and ask, “Which one is big?”
Reward success with immediate praise or a small reinforcer (like tickles or snacks).

You can also prompt expressive language by asking, “What is this?” and encouraging responses like “big ball” or “little car.”

Teaching Features: Ears, Tails, and Stripes

Beyond size, teaching children to notice features of objects and animals helps with vocabulary growth and attention to detail. This is especially important for language development and even early reading readiness.

For example:

  • Show pictures of animals with and without stripes.

  • Ask, “Which one has stripes?”

  • Or give verbal cues like, “Find the animal with a tail.”

You can also include features like:

  • Ears

  • Spots

  • Horns

  • Beaks

  • Colors

These types of feature-based lessons increase receptive language skills and help children answer “wh” questions more easily.

Generalizing Big Vs. Little and Features Across Settings

Don’t stop at one lesson. For true understanding, children need to generalize these concepts across:

  • Different environments (home, school, therapy sessions)

  • Different types of materials (toys, flashcards, books)

  • Varying examples (a big bear vs. a big truck)

The more variety you build in, the more likely your child will retain and use these concepts spontaneously.

Use What You Already Have at Home

You don’t need fancy materials to get started. Try using:

  • Stuffed animals of different sizes

  • Toy sets with similar objects (e.g., a family of bears or a tea set)

  • Picture books with clear images of size or feature differences

Just remember to start simple, be consistent, and keep sessions short and positive.

Top 5 FAQ Big Vs. Little and Features

As soon as your child is matching objects or labeling basic nouns, you can begin introducing simple size and feature concepts. You can see a list of general language skills here.

Keep teaching sessions short—5 to 10 minutes—and make them fun and interactive. You can build teaching into daily routines too. For professionals- we can teach you how to get kids excited to learn with our new professional membership. 

No. You can use household items, toys, and picture books to teach these concepts effectively.

Focus on receptive language—like matching or pointing—before expecting spoken responses. Pair language with visuals to boost understanding. 

Look for spontaneous use in new environments, with different materials, and without prompts.
