Handling Behavior Changes: A Teacher's Starter Guide

If you're reading this, you might be exhausted. You're watching a 3, 4, or 5 year old child in your classroom go through behavioral changes that you didn't expect, and you're not sure where to start. You want to help, but the tantrums, the refusals, the sudden outbursts feel overwhelming. You're probably wondering what you're missing, what you should try next, and whether what you're doing is even working.

You asked for a step-by-step guide to help your children encounter behavioral changes. That is exactly what this guide is about. For preschoolers with autism, learning disabilities, developmental delays, and behavioral challenges, behavior is communication. When a child's behavior changes, they are telling you something, even if they don't have the words yet. Your job is not to stop the behavior by force. Your job is to figure out what the behavior is saying, teach a better way to say it, and make that better way more successful than the old way.

Behavior is anything a person does. It is not just the things we don't want to see. Running, sitting, asking for help, crying, throwing a toy, saying please, all of these are behaviors. When we talk about behavior change, we are talking about increasing the behaviors we want to see and decreasing the ones that get in the way of learning and connection. Children do not manipulate. They learn. If a behavior keeps happening, it is because that behavior works for the child in some way. If we want to change it, we have to teach them a better way that works even more reliably.

1. Describe the behavior in clear, observable terms so anyone could recognize it.

When a behavior concerns you, write down exactly what it looks like. Use action words (kicks, screams, throws, hits) instead of feeling words (angry, frustrated, defiant). If you say "the child has tantrums," that is a start, but what does that tantrum look like? Does the child cry and drop to the floor? Do they throw materials? Do they hit themselves or others? Not all tantrums look the same. If you cannot describe the behavior so that another teacher could recognize it immediately, you do not have a clear enough picture yet.

For a 3 to 5 year old, behaviors often look like crying when asked to clean up, running away during circle time, grabbing toys from peers, or refusing to follow a direction. Describe what the child does, not what you think they feel. This keeps you from getting frustrated and helps you see the behavior as something you can teach, not something the child is doing to you.

2. Watch for what happens right before the behavior (the antecedent) and right after (the consequence).

Behaviors do not happen in a vacuum. Something triggers them, and something keeps them going. The antecedent is anything that happens right before the behavior. It could be a transition, a demand, losing access to a toy, or even just being tired or hungry. The consequence is what happens right after. Does the child get attention? Do they escape the task? Do they get the toy back?

In your preschool classroom, watch 1 specific behavior for 3 days. Write down what happened right before it each time. You might notice a pattern: the child throws materials every time you ask them to sit at the table, or they cry every time another child takes a toy. Once you see the pattern, you can change what happens before (give a visual warning before transitions) or after (do not let the behavior work by giving the toy back or removing the demand). Children learn from consequences. If the behavior keeps working, it will keep happening.

3. Teach the child what to do instead, and make that new behavior easier and more rewarding than the old one.

If a child screams to get your attention, teach them to tap your shoulder or say your name. If they throw toys when frustrated, teach them to ask for a break or point to a "help" card. The replacement behavior has to be something the child can already do or can learn quickly. Then, make it work every single time at first. If the child taps your shoulder, respond immediately. If they ask for a break, give it. The new behavior has to be more successful than the old one, or the child will go back to what they know works.

For young children with autism or developmental delays, this often looks like teaching them to use a picture to request instead of grabbing, or teaching them to wait by giving them something to hold while they wait. Prompt the new behavior before the old one starts. If you know the child usually screams when you ask them to clean up, show them the "all done" card before they scream and praise them immediately when they use it. That is how you replace the behavior, one moment at a time.

4. Use short, clear instructions and model what you want the child to do.

Young children, especially those with learning and developmental challenges, need instructions that are concrete and simple. Instead of saying "be nice," say "give the toy to Sarah." Instead of "stop that," say "sit down." Show them what it looks like. If you want the child to clean up, pick up 1 toy yourself and say "clean up" as you do it, then hand them a toy and guide their hand to the bin if needed. This is called modeling, and it is one of the most powerful ways to teach.

In a preschool classroom with 3 to 5 year olds, you can model during group time, during play, and during transitions. If a child does not know how to ask to join play, you can role-play it with another adult or peer first, then prompt the child to try. Pair your words with actions so the child sees exactly what you mean. The clearer your instruction and model, the faster the child will learn what you expect.

Your 5-Day Starter Plan

Day 1: Pick 1 behavior you want to decrease and 1 you want to increase. Write them down using action words only.

Day 2: Watch for the antecedent. What happens right before the behavior starts? Write it down every time you see it.

Day 3: Teach the replacement behavior. Show the child what to do instead, and prompt it before the problem behavior starts.

Day 4: Make the replacement behavior work every single time. Respond immediately and give the child what they need when they use the new behavior.

Day 5: Celebrate small wins. If the child used the new behavior even once, that is progress. Keep going.
