Fun with Patterns: The Secret Code Detective

Materials Needed

• Large paper or a whiteboard
• Crayons or washable markers
• Colored blocks, buttons, or toy pieces
• Picture cards or small household objects
• Paper and child-safe scissors
• Optional: a tablet or computer for a simple pattern game

Learning Objectives

By the end of the lesson, the child will be able to:

• Notice and describe a simple pattern.
• Continue an AB or AAB pattern.
• Create a pattern using objects, movements, sounds, or drawings.
• Explain what comes next and tell why.
• Understand that computer “codes” can be directions or patterns that help people and machines know what to do.

Success Criteria

Success looks like this:

• “I can find what repeats.”
• “I can tell what comes next.”
• “I can make my own pattern.”
• “I can use kind, safe directions.”

Introduction: The Pattern Detective

Hook: Say, “A friendly robot is trying to follow a pattern, but it does not know what comes next. Can you be a pattern detective and help it?”

Show a simple pattern such as:

Red, blue, red, blue, ___

Ask:

• “What do you notice?”
• “What should come next?”
• “How do you know?”

Tell the child: “Today we will look for repeating patterns, make our own patterns, and give safe directions like a helpful computer helper.”

Body: Learn and Practice

Part 1: I Do — Teacher or Parent Models

Place two objects in a repeating pattern, such as a block and a button:

Block, button, block, button

Think aloud:

“I see the block and button repeating. The pattern is block, button. After the block comes the button.”

Add another object and say:

“The next piece should be a button because the pattern repeats.”

Model a movement pattern:

Clap, tap, clap, tap

Say the pattern slowly while doing the movements. Invite the child to watch first, then copy.

Quick Check

Show or perform one pattern and pause:

• Red, yellow, red, yellow, ___
• Stomp, clap, stomp, clap, ___
• Circle, star, circle, star, ___

Ask the child to point to or say what comes next.

Part 2: We Do — Make Patterns Together

Work together to create patterns with blocks, toys, or household objects.

Begin with an AB pattern:

1. Choose two objects or colors.
2. Place the first object.
3. Place the second object.
4. Repeat the two-object rule.
5. Pause and let the child choose what comes next.

Example:

Toy car, teddy bear, toy car, teddy bear, ___

Next, try an AAB pattern:

Clap, clap, tap; clap, clap, tap; ___

Use think-pair-share adapted for homeschooling:

• Think: Let the child look quietly at the pattern.
• Tell: Ask the child to explain what repeats.
• Share: The child shows the answer to a parent, stuffed animal, sibling, or toy.

Formative Assessment

Give the child three short patterns. Notice whether the child can:

• Identify the repeating part.
• Choose the next item.
• Explain the choice using simple words.

Part 3: You Do — Create a Secret Pattern

Invite the child to choose one activity:

Choice A: Object Pattern

Make a pattern using toys, blocks, snacks, or safe household objects. The child hides the last item and asks an adult to guess what comes next.

Choice B: Movement Pattern

Create a pattern using movements, such as:

• Jump, clap, jump, clap
• Spin, touch toes, spin, touch toes
• Stomp, stomp, clap; stomp, stomp, clap

Choice C: Drawing Pattern

Draw a repeating pattern with shapes, lines, or colors. The child circles the part that repeats.

Choice D: Friendly Robot Directions

Pretend a stuffed animal is a robot. Give it three simple, safe directions:

1. “Take one step.”
2. “Clap two times.”
3. “Sit on the pillow.”

Explain: “Directions are like a little code. A code can tell someone what to do. We use safe and kind directions.”

Real-World Connection

Point out patterns in everyday life:

• Stripes on clothing
• Tiles on a floor
• Traffic lights
• Music beats
• Daily routines, such as brush teeth, put on shoes, and eat breakfast

Say, “Patterns help us know what may happen next. People, music, nature, and computers all use patterns.”

Summative Assessment: Pattern Detective Challenge

Present the child with three challenges:

1. Find it: Show an AB pattern and ask the child to point to the repeating part.
2. Finish it: Give the child an incomplete AAB pattern and ask what comes next.
3. Make it: Ask the child to create and explain a pattern of their own.

Simple Observation Checklist

• ☐ Notices a repeating pattern
• ☐ Completes an AB pattern
• ☐ Attempts an AAB pattern
• ☐ Creates a pattern independently or with help
• ☐ Explains what comes next
• ☐ Follows or gives safe, kind directions

Differentiation and Support

For a Child Who Needs More Support

• Use only two large, clearly different objects.
• Start with AB patterns before trying AAB patterns.
• Use a short pattern with four items.
• Let the child touch, move, or say each part.
• Offer two choices: “Does the red piece or blue piece come next?”
• Repeat the pattern slowly and use pointing or gestures.

For a Child Ready for More Challenge

• Create an ABC pattern, such as red, blue, yellow, red, blue, yellow.
• Ask the child to make a pattern for someone else to solve.
• Use sounds, movements, colors, and shapes in the same pattern.
• Ask the child to find patterns around the home.
• Invite the child to give a toy several directions in the correct order.

Feedback and Reflection

Give specific feedback, such as:

• “You noticed that red and blue repeat.”
• “You looked carefully before choosing the next piece.”
• “You made your own pattern and explained it clearly.”

Ask the child:

• “What was your favorite pattern?”
• “What was easy?”
• “What was tricky?”
• “Where can we find a pattern in our home?”

Conclusion: Tell What We Learned

Review together:

“Today we learned that a pattern is something that repeats. We found what comes next, made our own patterns, and used safe directions for a friendly robot.”

Finish with a cheerful call-and-response:

Adult: “Pattern!”
Child: “Repeats!”
Adult: “What comes next?”
Child: “I can find it!”
